Lab 146 - IOS XR IBGP Confederation

Pada lab sebelumnya kita telah belajar tentang IBGP Route Reflcetor pada IOS XR.. selanjutnya pada lab ini kita akan belajar tentang IBGP Confederation..

Berikut topologi yang akan kita gunakan
Pertama kita harus konfigurasi IP Address dan routing protocol IGP pada jaringan diatas.. pada lab ini kita akan menggunakan EIGRP yaaa.. jika ada yg belum bisa konfigurasi EIGRP di IOS XR bisa merujuk ke artikel berikut : Konfigurasi EIGRP di IOS XR..

Setelah konfigurasi EIGRP, hasilnya adalah sebagai berikut
RP/0/0/CPU0:IOS-XR1(config-eigrp-af-if)#do sh route eigrp Wed Jun 7 06:47:34.279 UTC D 2.2.2.2/32 [90/10752] via 12.12.12.2, 00:03:03, GigabitEthernet0/0/0/0 D 3.3.3.3/32 [90/15872] via 12.12.12.2, 00:01:12, GigabitEthernet0/0/0/0 D 4.4.4.4/32 [90/20992] via 12.12.12.2, 00:00:32, GigabitEthernet0/0/0/0 D 23.23.23.0/24 [90/15360] via 12.12.12.2, 00:03:03, GigabitEthernet0/0/0/0 D 34.34.34.0/24 [90/20480] via 12.12.12.2, 00:01:12, GigabitEthernet0/0/0/0
RP/0/0/CPU0:IOS-XR2(config-eigrp-af-if)#do sh route eigrp Wed Jun 7 06:48:06.896 UTC D 1.1.1.1/32 [90/10752] via 12.12.12.1, 00:03:17, GigabitEthernet0/0/0/0 D 3.3.3.3/32 [90/10752] via 23.23.23.3, 00:01:45, GigabitEthernet0/0/0/1 D 4.4.4.4/32 [90/15872] via 23.23.23.3, 00:01:05, GigabitEthernet0/0/0/1 D 34.34.34.0/24 [90/15360] via 23.23.23.3, 00:01:45, GigabitEthernet0/0/0/1

Oke.. pastikan hasilnya sudah seperti itu ya.. pastikan juga masing-masing router sudah bisa ping ke loopback0 router lainnya.. berikut contoh ping dari IOS-XR1 ke loopback0 router lainnya
RP/0/0/CPU0:IOS-XR1(config-eigrp-af-if)#do ping ipv4 2.2.2.2 Wed Jun 7 06:51:23.093 UTC Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 2.2.2.2, timeout is 2 seconds: !!!!!

Sending 5, 100-byte ICMP Echos to 3.3.3.3, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/6/19 ms RP/0/0/CPU0:IOS-XR1(config-eigrp-af-if)#do ping ipv4 4.4.4.4 Wed Jun 7 06:51:30.342 UTC Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 4.4.4.4, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/5/9 ms
Oke kalu sudah berhasil seperti diatas, selanjutnya kita akan konfigurasi IBGP dengan confederation..

Perhatikan topologi diatas, IOS-XR1 dan IOS-XR2 menggunaakn AS confederation 12 sedangkan IOS-XR3 dan IOS-XR4 menggunakan AS confederation 34..

Berikut konfigurasi pada IOS-XR1
RP/0/0/CPU0:IOS-XR1(config)#router bgp 12 RP/0/0/CPU0:IOS-XR1(config-bgp)#bgp confederation identifier 12 RP/0/0/CPU0:IOS-XR1(config-bgp)#address-family ipv4 unicast RP/0/0/CPU0:IOS-XR1(config-bgp-af)#network 11.11.11.11/32 RP/0/0/CPU0:IOS-XR1(config-bgp-af)#exit RP/0/0/CPU0:IOS-XR1(config-bgp)#neighbor 2.2.2.2 RP/0/0/CPU0:IOS-XR1(config-bgp-nbr)#remote-as 12 RP/0/0/CPU0:IOS-XR1(config-bgp-nbr)#update-source lo0 RP/0/0/CPU0:IOS-XR1(config-bgp-nbr)#address-family ipv4 unicast RP/0/0/CPU0:IOS-XR1(config-bgp-nbr-af)#commit
Selanjutnya berikut konfigurasi pada IOS-XR2
RP/0/0/CPU0:IOS-XR2(config)#router bgp 12 RP/0/0/CPU0:IOS-XR2(config-bgp)#bgp confederation identifier 12 RP/0/0/CPU0:IOS-XR2(config-bgp)#bgp confederation peers 34 RP/0/0/CPU0:IOS-XR2(config-bgp)#address-family ipv4 unicast RP/0/0/CPU0:IOS-XR2(config-bgp-af)#network 22.22.22.22/32 RP/0/0/CPU0:IOS-XR2(config-bgp-af)#exit RP/0/0/CPU0:IOS-XR2(config-bgp)#neighbor 1.1.1.1 RP/0/0/CPU0:IOS-XR2(config-bgp-nbr)#remote-as 12 RP/0/0/CPU0:IOS-XR2(config-bgp-nbr)#update-source lo0 RP/0/0/CPU0:IOS-XR2(config-bgp-nbr)#address-family ipv4 unicast RP/0/0/CPU0:IOS-XR2(config-bgp-nbr-af)#neighbor 3.3.3.3 RP/0/0/CPU0:IOS-XR2(config-bgp-nbr)#remote-as 34 RP/0/0/CPU0:IOS-XR2(config-bgp-nbr)#update-source lo0 RP/0/0/CPU0:IOS-XR2(config-bgp-nbr)#address-family ipv4 unicast RP/0/0/CPU0:IOS-XR2(config-bgp-nbr-af)#commit
Perhatikan bahwa pada IOS-XR2 kita perlu mengkonfigurisakan ebgp-multihop saat neighbor 3.3.3.3.. ini dikarenakan IOS-XR2 menganggap IOS-XR3 seolah-olah adalah external AS.. sedangkan untuk peering EBGP nilai ttl nya adalah 1.. jadi kita harus memperbesar nilai ttl menggunakan perintah ebgp-multihop ini..

Selanjutnya berikut konfigurasi di IOS-XR3
RP/0/0/CPU0:IOS-XR3(config)#router bgp 34 RP/0/0/CPU0:IOS-XR3(config-bgp)#bgp confederation identifier 1234 RP/0/0/CPU0:IOS-XR3(config-bgp)#bgp confederation peers 12 RP/0/0/CPU0:IOS-XR3(config-bgp)#address-family ipv4 unicast RP/0/0/CPU0:IOS-XR3(config-bgp-af)#network 33.33.33.33/32 RP/0/0/CPU0:IOS-XR3(config-bgp-af)#exit RP/0/0/CPU0:IOS-XR3(config-bgp)#neighbor 2.2.2.2 RP/0/0/CPU0:IOS-XR3(config-bgp-nbr)#remote-as 12 RP/0/0/CPU0:IOS-XR3(config-bgp-nbr)#update-source lo0 RP/0/0/CPU0:IOS-XR3(config-bgp-nbr)#address-family ipv4 unicast RP/0/0/CPU0:IOS-XR3(config-bgp-nbr-af)#neighbor 4.4.4.4 RP/0/0/CPU0:IOS-XR3(config-bgp-nbr)#remote-as 34 RP/0/0/CPU0:IOS-XR3(config-bgp-nbr)#update-source lo0 RP/0/0/CPU0:IOS-XR3(config-bgp-nbr)#address-family ipv4 unicast RP/0/0/CPU0:IOS-XR3(config-bgp-nbr-af)#commit
Perhatikan bahwa kita juga perlu mengkonfigurasikan ebgp-multihop pada IOS-XR3

Yang terahir, berikut konfigurasi pada IOS-XR4
RP/0/0/CPU0:IOS-XR4(config)#router bgp 34 RP/0/0/CPU0:IOS-XR4(config-bgp)#bgp confederation identifier 1234 RP/0/0/CPU0:IOS-XR4(config-bgp)#address-family ipv4 unicast RP/0/0/CPU0:IOS-XR4(config-bgp-af)#network 44.44.44.44/32 RP/0/0/CPU0:IOS-XR4(config-bgp-af)#exit RP/0/0/CPU0:IOS-XR4(config-bgp)#neighbor 3.3.3.3 RP/0/0/CPU0:IOS-XR4(config-bgp-nbr)#remote-as 34 RP/0/0/CPU0:IOS-XR4(config-bgp-nbr)#update-source lo0 RP/0/0/CPU0:IOS-XR4(config-bgp-nbr)#address-family ipv4 unicast RP/0/0/CPU0:IOS-XR4(config-bgp-nbr-af)#commit
Oke.. konfigurasi sudah selesai.. Untuk pengujian,, pastikan IOS-XR1 menerima network dari IOS-XR2, IOS-XR3, dan IOS-XR4
RP/0/0/CPU0:IOS-XR1(config-bgp-nbr-af)#do sh bgp Wed Jun 7 07:31:04.430 UTC BGP router identifier 1.1.1.1, local AS number 12 BGP generic scan interval 60 secs Non-stop routing is enabled BGP table state: Active Table ID: 0xe0000000 RD version: 6 BGP main routing table version 6 BGP NSR Initial initsync version 2 (Reached) BGP NSR/ISSU Sync-Group versions 0/0 BGP scan interval 60 secs Status codes: s suppressed, d damped, h history, * valid, > best i - internal, r RIB-failure, S stale, N Nexthop-discard Origin codes: i - IGP, e - EGP, ? - incomplete Network Next Hop Metric LocPrf Weight Path *> 11.11.11.11/32 0.0.0.0 0 32768 i *>i22.22.22.22/32 2.2.2.2 0 100 0 i *>i33.33.33.33/32 3.3.3.3 0 100 0 (34) i *>i44.44.44.44/32 4.4.4.4 0 100 0 (34) i Processed 4 prefixes, 4 paths
Oke sudah berhasil ya.. untuk lebih memastikan, kita coba lihat tabel routing di IOS-XR1
RP/0/0/CPU0:IOS-XR1(config-bgp-nbr-af)#do sh route bgp Wed Jun 7 07:31:43.497 UTC B 22.22.22.22/32 [200/0] via 2.2.2.2, 00:11:32 B 33.33.33.33/32 [200/0] via 3.3.3.3, 00:09:05 B 44.44.44.44/32 [200/0] via 4.4.4.4, 00:08:35
Oke sudah lengkap... sekarang kita coba lakukan ping yaa
RP/0/0/CPU0:IOS-XR1(config-bgp-nbr-af)#do ping 22.22.22.22 sou l1 Wed Jun 7 07:32:10.695 UTC Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 22.22.22.22, timeout is 2 seconds: !!!!!

Lab 145 - IOS XR IBGP Route Reflector

Sebelumnya kita telah belajar tentang IGP di IOS XR,,. yaitu OSPF dan EIGRP.. selanjutnya pada lab ini kita akan belajar tentang EGP,, yaitu BGP..

Kita akan ngelab IBGP dengan menggunakan Route Reflector.. berikut topologi yang akan kita gunakan
Perhatikan masing-masing router mempunyai dua IP Loopback.. nantinya interface loopback0 pada masing-masing router akan kita advertise ke OSPF.. selanjutnya interface loopback1 pada masing-masing router akan kita advertise ke IBGP..

Oke langsung saja, Diasumsikan kita sudah konfigurasi OSPF ya.. nanti hasilnya harus nya seperti ini..

Kalau masih ada yang belum bisa konfigurasi OSPF di IOS XR, bisa merujuk ke artikel berikut ya : Konfigurasi OSPF di IOS XR

Oke.. setelah konfigurasi OSPF selesai.. pastikan masing-masing router bisa ping ke loopback0 dari router lain ya.. kita coba ping dari IOS-XR1 ke loopback0 IOS-XR2-4
RP/0/0/CPU0:IOS-XR1(config-ospf-ar-if)#do ping 2.2.2.2 Mon Jun 5 01:26:51.382 UTC Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 2.2.2.2, timeout is 2 seconds: !!!!!

Oke sudah jalan semua ya.. sekarang saatnya kita mengkonfigurasi IBGP... pada topologi ini IOS-XR4 akan menjadi Route Reflector ya.. jadi nanti IOS-XR1, 2, dan 3 hanya perlua peering ke IOS-XR4..

Oke langsung saja.. berikut konfigurasi di IOS-XR1

Berikut konfigurasi di IOS-XR4.. pada IOS-XR4 ini kita akan konfiguruasi peering group ya.. karena IOS-XR4 harus peering ke 3 router.. kalau peering satu-satu kelamaan.. jadi lebih baik pake group aja
RP/0/0/CPU0:IOS-XR4(config)#router bgp 1234 RP/0/0/CPU0:IOS-XR4(config-bgp)#address-family ipv4 unicast RP/0/0/CPU0:IOS-XR4(config-bgp-af)#net 44.44.44.44/32 RP/0/0/CPU0:IOS-XR4(config-bgp-af)#exit RP/0/0/CPU0:IOS-XR4(config-bgp)#neighbor-group IBGP RP/0/0/CPU0:IOS-XR4(config-bgp-nbrgrp)#remote-as 1234 RP/0/0/CPU0:IOS-XR4(config-bgp-nbrgrp)#update-source lo0 RP/0/0/CPU0:IOS-XR4(config-bgp-nbrgrp)#address-family ipv4 unicast RP/0/0/CPU0:IOS-XR4(config-bgp-nbrgrp-af)#route-reflector-client RP/0/0/CPU0:IOS-XR4(config-bgp-nbrgrp-af)#exit RP/0/0/CPU0:IOS-XR4(config-bgp-nbrgrp)#exit RP/0/0/CPU0:IOS-XR4(config-bgp)#neigh 1.1.1.1 RP/0/0/CPU0:IOS-XR4(config-bgp-nbr)#use neighbor-group IBGP RP/0/0/CPU0:IOS-XR4(config-bgp-nbr)#nei 2.2.2.2 RP/0/0/CPU0:IOS-XR4(config-bgp-nbr)#use neighbor-group IBGP RP/0/0/CPU0:IOS-XR4(config-bgp-nbr)#nei 3.3.3.3 RP/0/0/CPU0:IOS-XR4(config-bgp-nbr)#use neighbor-group IBGP RP/0/0/CPU0:IOS-XR4(config-bgp-nbr)#commit
Oke untuk pengujian, kita bisa menggunakan perintah berikut
RP/0/0/CPU0:IOS-XR1(config-if)#do sh bgp sum Mon Jun 5 01:50:04.631 UTC BGP router identifier 1.1.1.1, local AS number 1234 BGP generic scan interval 60 secs Non-stop routing is enabled BGP table state: Active Table ID: 0xe0000000 RD version: 6 BGP main routing table version 6 BGP NSR Initial initsync version 2 (Not Reached) BGP NSR/ISSU Sync-Group versions 0/0 BGP scan interval 60 secs BGP is operating in STANDALONE mode.

Lab 144 - IOS XR EIGRP Routing

Oke sesuai janji, kita masih lanjut belajar IOS XR yaa.. setelah sebelumnya kita belajar tentang konfigurasi OSPF di IOS XR, selanjutnya pada lab ini kita akan belajar konfigurasi routing protocol EIGRP pada IOS XR..

Untuk topologinya kita akan menggunakan topologi seperti berikut yaa
Pertama kita konfigurasi addressingnya dulu yaa..
RP/0/0/CPU0:IOS-XR1(config)#int g0/0/0/0 RP/0/0/CPU0:IOS-XR1(config-if)#no sh RP/0/0/CPU0:IOS-XR1(config-if)#ipv4 add 12.12.12.1/24 RP/0/0/CPU0:IOS-XR1(config-if)#int l0 RP/0/0/CPU0:IOS-XR1(config-if)#ipv4 add 1.1.1.1/32 RP/0/0/CPU0:IOS-XR1(config-if)#int l1 RP/0/0/CPU0:IOS-XR1(config-if)#ipv4 add 11.11.11.11/32 RP/0/0/CPU0:IOS-XR1(config-if)#commit Sat Jun 3 15:06:51.991 UTC

Oke.. lanjut sekarang kita konfigurasikan EIGRP pada ketiga router tersebut... Berikut konfigurasi di IOS-XR1
RP/0/0/CPU0:IOS-XR1(config)#router eigrp 1 RP/0/0/CPU0:IOS-XR1(config-eigrp)#address-family ipv4 RP/0/0/CPU0:IOS-XR1(config-eigrp-af)#interface g0/0/0/0 RP/0/0/CPU0:IOS-XR1(config-eigrp-af-if)#int l0 RP/0/0/CPU0:IOS-XR1(config-eigrp-af-if)#int l1 RP/0/0/CPU0:IOS-XR1(config-eigrp-af-if)#commit
Berikut konfigurasi di IOS-XR2
RP/0/0/CPU0:IOS-XR2(config)#router eigrp AS1 RP/0/0/CPU0:IOS-XR2(config-eigrp)#address-family ipv4 RP/0/0/CPU0:IOS-XR2(config-eigrp-af)#autonomous-system 1 RP/0/0/CPU0:IOS-XR2(config-eigrp-af)#int g0/0/0/0 RP/0/0/CPU0:IOS-XR2(config-eigrp-af-if)#int g0/0/0/1 RP/0/0/CPU0:IOS-XR2(config-eigrp-af-if)#int l0 RP/0/0/CPU0:IOS-XR2(config-eigrp-af-if)#int l1 RP/0/0/CPU0:IOS-XR2(config-eigrp-af-if)#commit
Berikut konfigurasi di IOS-XR3
RP/0/0/CPU0:IOS-XR3(config)#router eigrp 1 RP/0/0/CPU0:IOS-XR3(config-eigrp)#address-family ipv4 RP/0/0/CPU0:IOS-XR3(config-eigrp-af)#int g0/0/0/0 RP/0/0/CPU0:IOS-XR3(config-eigrp-af-if)#int l0 RP/0/0/CPU0:IOS-XR3(config-eigrp-af-if)#int l1 RP/0/0/CPU0:IOS-XR3(config-eigrp-af-if)#commit
Untuk pengujian, pertama kita coba lihat apakah masing-masing router sudah menjalankan routing protocol eigrp dengan perintah berikut
RP/0/0/CPU0:IOS-XR1(config-eigrp-af-if)#do sh protocol eigrp Sat Jun 3 16:43:22.814 UTC Routing Protocol: EIGRP, instance 1 Default context AS: 1, Router ID: 1.1.1.1 Address Family: IPv4 Default networks not flagged in outgoing updates Default networks not accepted from incoming updates Distance: internal 90, external 170 Maximum paths: 4 EIGRP metric weight K1=1, K2=0, K3=1, K4=0, K5=0, K6=0 EIGRP metric rib scale 128 EIGRP metric version 64-bit EIGRP maximum hopcount 100 EIGRP maximum metric variance 1 EIGRP NSF: enabled NSF-aware route hold timer is 480s NSF signal timer is 20s NSF converge timer is 300s Time since last restart is 00:13:09 SIA Active timer is 180s Interfaces: Loopback0 Loopback1 GigabitEthernet0/0/0/0
Perhatikan bahwa IOS-XR1 sudah menjalankan routing protocol EIGRP dengan AS 1, router-id 1.1.1.1, metric version 64 bit, dll. kita bisa melihat informasi tentang routing protocol EIGRP yang sedang berjalan dengan perintah diatas..

Selanjutnya, kita juga bisa melihat neighbor untuk melakukan pengujian, kita akan coba lihat neighbor di IOS-XR2
RP/0/0/CPU0:IOS-XR2#show eigrp neighbors Sat Jun 3 16:46:44.920 UTC IPv4-EIGRP VR(AS1) Neighbors for AS(1) VRF default H Address Interface Hold Uptime SRTT RTO Q Seq (sec) (ms) Cnt Num 1 23.23.23.3 Gi0/0/0/1 13 00:00:15 25 200 0 3 0 12.12.12.1 Gi0/0/0/0 11 00:09:35 7 200 0 7
Perhatikan bahwa IOS-XR2 sudah adjacency dengan IOS-XR1 dan IOS-XR3.. Selanjutnya kita juga bisa melihat tabel routing untuk melakukan pengujian.. Berikut tabel routing pada IOS-XR1
RP/0/0/CPU0:IOS-XR1(config-eigrp-af-if)#do sh route eigrp Sat Jun 3 16:47:45.816 UTC D 2.2.2.2/32 [90/10752] via 12.12.12.2, 00:10:36, GigabitEthernet0/0/0/0 D 3.3.3.3/32 [90/15872] via 12.12.12.2, 00:01:16, GigabitEthernet0/0/0/0 D 22.22.22.22/32 [90/10752] via 12.12.12.2, 00:10:36, GigabitEthernet0/0/0/0 D 23.23.23.0/24 [90/15360] via 12.12.12.2, 00:01:18, GigabitEthernet0/0/0/0 D 33.33.33.33/32 [90/15872] via 12.12.12.2, 00:01:16, GigabitEthernet0/0/0/0
Perhatikan bahwa IOS-XR1 sudah memiliki tabel routing yang lengkap.. selanjutnya pengujian terahir yang dapat kita lakukan adalah dengan melakukan ping.. berikut percobaan ping dari IOS-XR1 ke loopback XR2 dan XR3
RP/0/0/CPU0:IOS-XR1(config-eigrp-af-if)#do ping 2.2.2.2 Sat Jun 3 16:48:44.142 UTC Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 2.2.2.2, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/9 ms RP/0/0/CPU0:IOS-XR1(config-eigrp-af-if)#do ping 3.3.3.3 Sat Jun 3 16:48:49.172 UTC Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 3.3.3.3, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/9 ms
Oke.. sudah work semua yaaaa...

Alhamdulillah lab ke tiga kita tentang IOS XR sudah selesai.. semoga bermanfaat ya.. In Syaa Allah besok kita masih akan belajar tentang IOS XR... keep spirit yaa!!!

Lab 143 - IOS XR OSPF Routing

Pada lab sebelumnya kita sudah belajar tentang konfigurasi static routing di IOS XR.. Selanjutnya pada lab ini kita akan belajar konfigurasi routing OSPF pada IOS XR. Berikut topologi yang akan kita gunakan pada lab ini
Pada topologi diatas kita juga harus konfigurasi virtual link ya.. karena Area 2 tidak terhubung langsung dengan Area 0..

Oke pertama kita konfigurasikan ip address pada ketiga IOS XR sesuai topologi diatas
RP/0/0/CPU0:IOS-XR1(config)#int g0/0/0/0 RP/0/0/CPU0:IOS-XR1(config-if)#no sh RP/0/0/CPU0:IOS-XR1(config-if)#ipv4 add 12.12.12.1/24 RP/0/0/CPU0:IOS-XR1(config-if)#int l0 RP/0/0/CPU0:IOS-XR1(config-if)#ipv4 add 1.1.1.1/32 RP/0/0/CPU0:IOS-XR1(config-if)#int l1 RP/0/0/CPU0:IOS-XR1(config-if)#ipv4 add 11.11.11.11/32 RP/0/0/CPU0:IOS-XR1(config-if)#commit Sat Jun 3 15:06:51.991 UTC

RP/0/0/CPU0:IOS-XR3(config)#int g0/0/0/0 RP/0/0/CPU0:IOS-XR3(config-if)#no sh RP/0/0/CPU0:IOS-XR3(config-if)#ipv4 add 23.23.23.3/24 RP/0/0/CPU0:IOS-XR3(config-if)#int l0 RP/0/0/CPU0:IOS-XR3(config-if)#ipv4 add 3.3.3.3/32 RP/0/0/CPU0:IOS-XR3(config-if)#int l1 RP/0/0/CPU0:IOS-XR3(config-if)#ipv4 add 33.33.33.33/32 RP/0/0/CPU0:IOS-XR3(config-if)#commit
Oke.. konfigurasi ip address sudah selesai ya.. untuk pengujian, kita coba lakukan uji ping ke directly connected network masing2 router.. Berikut pengujian ping dari IOS-XR1 ke IOS-XR2
RP/0/0/CPU0:IOS-XR1(config-if)#do ping ipv4 12.12.12.2 Sat Jun 3 15:10:34.386 UTC Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 12.12.12.2, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/14/59 ms
Oke dari IOS-XR1 ke IOS-XR2 berhasil.. sekarang kita coba dari IOS-XR2 ke IOS-XR3
RP/0/0/CPU0:IOS-XR2(config-if)#do ping ipv4 23.23.23.3 Sat Jun 3 15:11:08.853 UTC Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 23.23.23.3, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/10/39 ms
Oke.. sudah berhasil juga ya..

Lanjut kita konfigurasi OSPF pada ketiga router tersebut.. perhatikan konfigurasinya harus sesuai topologi ya.. pada topologi kita diminta untuk mengkonfigurasi OSPF dengan 3 area..

Oke langsung saja, berikut konfigurasi OSPF pada IOS-XR1
RP/0/0/CPU0:IOS-XR1(config)#router ospf 1 RP/0/0/CPU0:IOS-XR1(config-ospf)#router-id 1.1.1.1 RP/0/0/CPU0:IOS-XR1(config-ospf)#area 0 RP/0/0/CPU0:IOS-XR1(config-ospf-ar)#interface lo0 RP/0/0/CPU0:IOS-XR1(config-ospf-ar-if)#int l1 RP/0/0/CPU0:IOS-XR1(config-ospf-ar-if)#area 1 RP/0/0/CPU0:IOS-XR1(config-ospf-ar)#int g0/0/0/0 RP/0/0/CPU0:IOS-XR1(config-ospf-ar-if)#commit
Perhatikan bahwa kita tidak menggunakan perintah network pada IOS XR, kita menggunakan perintah interface seperti diatas, untuk pengujian kita coba lihat running-config nya ya
RP/0/0/CPU0:IOS-XR1(config-ospf)#do sh run router ospf Sat Jun 3 15:21:25.241 UTC router ospf 1 router-id 1.1.1.1 area 0 interface Loopback0 interface Loopback1 ! ! area 1 interface GigabitEthernet0/0/0/0 ! !
Oke.. sekarang lanjut konfigurasi di IOS-XR2 yaa

Lab 142 - IOS XR Static Routing

Sejauh ini kita sudah belajar tentang Cisco IOS.. sekarang sudah saatnya untuk berkembang nih.. sekarang kita akan belajar tentang Cisco IOS XR..

apa sih bedanya antara Cisco IOS dengan Cisco IOS XR? Secara umum Cisco IOS XR lebih stabil dan memiliki fitur yang lebih advanced.. biasanya sih IOS XR digunakan di service provider.. sejauh ini itu sih yang saya tau tentang IOS XR,.. belum pernah implement juga sih.. hehehe

Oke langsung saja pada lab ini kita akan belajar konfigurasi static routing di IOS XR. berikut topologi yang akan kita gunakan pada lab ini
Nantinya kita akan menggunakan static routing di IOS XR-1 dan default route di IOS XR-2.

Pertama kita konfigurasikan IP Address pada IOS XR-1 dan 2 sesuai topologi diatas. Berikut konfigurasi di IOS-XR1
RP/0/0/CPU0:ios#conf t Sat Jun 3 14:32:33.568 UTC RP/0/0/CPU0:ios(config)#hostname IOS-XR1
Konfigurasi diatas belum masuk ke konfig IP sih.. tapi nyadar nda kalau ada yang beda? perhatikan bahwa setelah konfig hostname, tidak langsung berubah.. hal ini karena kita harus menggunakan perintah commit terlebih dahulu
RP/0/0/CPU0:ios(config)#commit Sat Jun 3 14:34:34.429 UTC RP/0/0/CPU0:IOS-XR1(config)#
Perhatikan bahwa saat ini hostname sudah berubah. intinya kita harus mengetikkan perintah commit agar konfigurasi yg kita lakukan bisa dijalankan.

Oke sekarang kita konfigurasikan IP Address nya ya.. tapi sebelumnya kita coba lihat status interfacenya dulu
RP/0/0/CPU0:IOS-XR1(config)#do show ipv4 interface brief Sat Jun 3 14:36:41.571 UTC Interface IP-Address Status Protocol GigabitEthernet0/0/0/0 unassigned Shutdown Down GigabitEthernet0/0/0/1 unassigned Shutdown Down GigabitEthernet0/0/0/2 unassigned Shutdown Down
Perhatikan bahwa perintah untuk melihat status interface pun sedikit berbeda dengan Cisco IOS. Selanjutnya berikut perintah untuk konfigurasi ip address di IOS XR
RP/0/0/CPU0:IOS-XR1(config)#int gi0/0/0/0 RP/0/0/CPU0:IOS-XR1(config-if)#no shutdown RP/0/0/CPU0:IOS-XR1(config-if)#ipv4 address 12.12.12.1/24
Sekarang kita coba lihat status interface nya
RP/0/0/CPU0:IOS-XR1(config)#do show ipv4 interface brief Sat Jun 3 14:36:41.571 UTC Interface IP-Address Status Protocol GigabitEthernet0/0/0/0 unassigned Shutdown Down GigabitEthernet0/0/0/1 unassigned Shutdown Down GigabitEthernet0/0/0/2 unassigned Shutdown Down
Nah lho.. kog masih belum ada konfignya? padahal kan kita sudah konfig...???

Hayoo.. sudah lupa kah? kan sudah saya bilang harus commit dulu... kita coba commit dulu yaa
RP/0/0/CPU0:IOS-XR1(config-if)#commit RP/0/0/CPU0:IOS-XR1(config-if)#do sho ipv4 int br Sat Jun 3 14:41:06.273 UTC Interface IP-Address Status Protocol GigabitEthernet0/0/0/0 12.12.12.1 Up Up GigabitEthernet0/0/0/1 unassigned Shutdown Down GigabitEthernet0/0/0/2 unassigned Shutdown Down
Nah.. setelah commit baru deh konfig IP nya jalan.. Lanjut kita konfigurasi interface loopback nya ya
RP/0/0/CPU0:IOS-XR1(config-if)#int lo0 RP/0/0/CPU0:IOS-XR1(config-if)#ipv4 add 1.1.1.1/32 RP/0/0/CPU0:IOS-XR1(config-if)#int l1 RP/0/0/CPU0:IOS-XR1(config-if)#ipv4 add 11.11.11.11/32 RP/0/0/CPU0:IOS-XR1(config-if)#commit Sat Jun 3 14:42:09.338 UTC
Kita coba lihat status interfacenya lagi
RP/0/0/CPU0:IOS-XR1(config-if)#do sh ipv4 int br Sat Jun 3 14:42:30.357 UTC Interface IP-Address Status Protocol Loopback0 1.1.1.1 Up Up Loopback1 11.11.11.11 Up Up GigabitEthernet0/0/0/0 12.12.12.1 Up Up GigabitEthernet0/0/0/1 unassigned Shutdown Down GigabitEthernet0/0/0/2 unassigned Shutdown Down
Oke sudah sesuai ya.. sekarang lanjut kita konfigurasi di IOS XR-2
RP/0/0/CPU0:ios(config)#host IOS-XR2 RP/0/0/CPU0:ios(config)#int g0/0/0/0 RP/0/0/CPU0:ios(config-if)#no sh RP/0/0/CPU0:ios(config-if)#ipv4 add 12.12.12.2/24 RP/0/0/CPU0:ios(config-if)#int l0 RP/0/0/CPU0:ios(config-if)#ipv4 add 2.2.2.2/32 RP/0/0/CPU0:ios(config-if)#int l1 RP/0/0/CPU0:ios(config-if)#ipv4 add 22.22.22.22/32 RP/0/0/CPU0:ios(config-if)#commit RP/0/0/CPU0:IOS-XR2(config-if)#do sh ipv4 int br Sat Jun 3 14:43:42.482 UTC Interface IP-Address Status Protocol Loopback0 2.2.2.2 Up Up Loopback1 22.22.22.22 Up Up GigabitEthernet0/0/0/0 12.12.12.2 Up Up GigabitEthernet0/0/0/1 unassigned Shutdown Down GigabitEthernet0/0/0/2 unassigned Shutdown Down
Oke.. konfigurasi IP Address sudah selesai, sekarang lanjut kita konfigurasikan routing static nya..

Disini kita akan konfigurasi routing static di IOS XR1 dan static default route di IOS XR2. Berikut konfigurasi static routing di IOS XR1
RP/0/0/CPU0:IOS-XR1(config)#router static address-family ipv4 unicast 2.2.2.2/32 12.12.12.2 RP/0/0/CPU0:IOS-XR1(config)#router static address-family ipv4 unicast 22.22.22.22/32 12.12.12.2 RP/0/0/CPU0:IOS-XR1(config)#commit
Untuk pengujian, kita bisa menggunakan perintah show run ataupun melihat tabel routing seperti berikut
RP/0/0/CPU0:IOS-XR1(config)#do sh run router static Sat Jun 3 14:47:37.936 UTC router static address-family ipv4 unicast 2.2.2.2/32 12.12.12.2 22.22.22.22/32 12.12.12.2 ! ! RP/0/0/CPU0:IOS-XR1(config)#do sh route Gateway of last resort is not set L 1.1.1.1/32 is directly connected, 00:05:46, Loopback0 S 2.2.2.2/32 [1/0] via 12.12.12.2, 00:00:42 L 11.11.11.11/32 is directly connected, 00:05:46, Loopback1 C 12.12.12.0/24 is directly connected, 00:06:57, GigabitEthernet0/0/0/0 L 12.12.12.1/32 is directly connected, 00:06:57, GigabitEthernet0/0/0/0 S 22.22.22.22/32 [1/0] via 12.12.12.2, 00:00:42
Oke.. saya rasa konfigurasi di IOS XR1 sudah selesai.. bisa difahami kan ya? meski perintahnya aga berbeda tapi konsepnya sama aja kog dengan IOS biasa..

Sekarang kita lanjut konfigurasi default route di IOS XR2
RP/0/0/CPU0:IOS-XR2(config)#router static address-family ipv4 unicast
0.0.0.0/0 12.12.12.1 RP/0/0/CPU0:IOS-XR2(config)#commit RP/0/0/CPU0:IOS-XR2(config)#do sh route Gateway of last resort is 12.12.12.1 to network 0.0.0.0 S* 0.0.0.0/0 [1/0] via 12.12.12.1, 00:00:17 L 2.2.2.2/32 is directly connected, 00:06:28, Loopback0 C 12.12.12.0/24 is directly connected, 00:06:28, GigabitEthernet0/0/0/0 L 12.12.12.2/32 is directly connected, 00:06:28, GigabitEthernet0/0/0/0 L 22.22.22.22/32 is directly connected, 00:06:28, Loopback1
Oke.. saya rasa konfigurasi sudah selesai.. sekarang kita lakukan pengujian ping yaa..Berikut pengujian ping dari IOS XR1 ke loopback XR2
RP/0/0/CPU0:IOS-XR1(config)#do ping ipv4 2.2.2.2 Sat Jun 3 14:50:49.653 UTC Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 2.2.2.2, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/16/69 ms RP/0/0/CPU0:IOS-XR1(config)#do ping ipv4 22.22.22.22 Sat Jun 3 14:50:55.222 UTC Type escape sequence to abort.

Oke berhasil semua ya... sekarang kita coba ping dari IOS XR2 ke loopback XR1
RP/0/0/CPU0:IOS-XR2(config)#do ping ipv4 1.1.1.1 Sat Jun 3 14:51:41.599 UTC Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 1.1.1.1, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms RP/0/0/CPU0:IOS-XR2(config)#do ping ipv4 11.11.11.11 Sat Jun 3 14:51:45.579 UTC Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 11.11.11.11, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms
Oke jalan semua ya.....

Alhamdulillah lab pertama kita tentang IOS XR sudah jalan.. sampai disini dulu ya.. sampai jumpa di artikel selanjutnya, In Syaa Allah masih akan tentang IOS XR..

Lab 141 - DMVPN Phase II Dynamic Mapping EIGRP

Pada lab sebelumnya kita sudah melakukan konfigurasi DMPVN Phase II menggunakan OSPF. Selanjunya pada lab ini kita juga akan konfigurasi DMVPN Phase II.. namun kali ini kita akan menggunakan EIGRP sebagai routing protocol nya.

Kita akan menggunakan konfigurasi dari lab sebelumnya ya.. kita hanya akan mengubah routing protocol nya saja.. pertama hapus konfigurasi OSPF di seluruh router
R1(config-if)#no router ospf 1
R2(config-if)#no router ospf 1
R3(config-if)#no router ospf 1
Sekarang kita konfigurasikan EIGRP
R1(config)#router ei 1 R1(config-router)#net 10.10.10.0 R1(config-router)#net 1.1.1.1 R1(config-router)#int tun0 R1(config-if)#no ip split-horizon eigrp 1
R2(config)#router ei 1 R2(config-router)#net 10.10.10.0 R2(config-router)#net 2.2.2.2
R3(config)#router ei 1 R3(config-router)#net 10.10.10.0 R3(config-router)#net 3.3.3.3
Kita perlu menon-aktifkan split horizon di sisi hub. tujuannya adalah agar spoke menerima tabel routing dari spoke yang lain..

Oke sekarang kita coba lihat tabel routing di R2 (spoke)
R2(config-router)#do sh ip route ei Gateway of last resort is 24.24.24.4 to network 0.0.0.0 1.0.0.0/32 is subnetted, 1 subnets D 1.1.1.1 [90/27008000] via 10.10.10.1, 00:00:08, Tunnel0 3.0.0.0/32 is subnetted, 1 subnets D 3.3.3.3 [90/28288000] via 10.10.10.1, 00:01:36, Tunnel0
Perhatikan bahwa untuk menuju 3.3.3.3 (spoke yang lain), R2 masih harus melewati hub. Untuk lebih memastikan kita coba trace,
R2(config-router)#do trace 3.3.3.3 Type escape sequence to abort. Tracing the route to 3.3.3.3 VRF info: (vrf in name/id, vrf out name/id) 1 10.10.10.1 1 msec 1 msec 1 msec 2 10.10.10.3 0 msec 0 msec 0 msec
berarti masih phase 1 dong? Iya!

Untuk mengubah agar menjadi Phase 2, kita perlu melakukan konfigurasi tambahan pada EIGRP seperti berikut
R1(config-router)#int tun0 R1(config-if)#no ip next-hop-self eigrp 1
Sekarang kita coba lihat tabel routing di R2 lagi.
R2(config-router)#do sh ip route eigrp Gateway of last resort is 24.24.24.4 to network 0.0.0.0 1.0.0.0/32 is subnetted, 1 subnets D 1.1.1.1 [90/27008000] via 10.10.10.1, 00:00:03, Tunnel0 3.0.0.0/32 is subnetted, 1 subnets D 3.3.3.3 [90/28288000] via 10.10.10.3, 00:00:01, Tunnel0
Perhatikan sekarang kalau R2 mau ke 3.3.3.3, sudah langsung via R3. tidak perlu via R1 (hub) lagi.. kita coba trace
R2(config-router)#do trace 3.3.3.3 Type escape sequence to abort. Tracing the route to 3.3.3.3 VRF info: (vrf in name/id, vrf out name/id) 1 10.10.10.3 1 msec 0 msec 0 msec
Oke DMVPN Phase 2 nya sudah jalan.
