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

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

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

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

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

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-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-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

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

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:

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-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 ping sudah jalan semua ya...

Alhamdulillah lab kedua kita tentang IOS XR sudah berhasil.. sampai ketemu di artikel selanjutnya yaa.. In Syaa Allah masih akan tetap tentang IOS XR

{ Read More }

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

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

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 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

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

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
