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

RP/0/0/CPU0:IOS-XR2(config)#int g0/0/0/0
RP/0/0/CPU0:IOS-XR2(config-if)#no sh
RP/0/0/CPU0:IOS-XR2(config-if)#ipv4 add 12.12.12.2/24    

RP/0/0/CPU0:IOS-XR2(config-if)#int l0
RP/0/0/CPU0:IOS-XR2(config-if)#ipv4 add 2.2.2.2/32

RP/0/0/CPU0:IOS-XR2(config-if)#int l1
RP/0/0/CPU0:IOS-XR2(config-if)#ipv4 add 22.22.22.22/32

RP/0/0/CPU0:IOS-XR2(config-if)#int g0/0/0/1
RP/0/0/CPU0:IOS-XR2(config-if)#no sh
RP/0/0/CPU0:IOS-XR2(config-if)#ipv4 add 23.23.23.2/24

RP/0/0/CPU0:IOS-XR2(config-if)#commit

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.. 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!!!
