Keunggulan IS-IS dibandingkan dengan OSPF adalah pada IS-IS dapat menjalankan IPv4 dan IPv6 dalam interface yg sama secara bersamaan.
Petunjuk Lab :
- Menjalankan Ipv4 dan Ipv6 pada routing IS-IS dalam satu interface yang sama.
Topologi Lab :
Metode Lab :
- Gunakan topologi dan konfigurasi pada Lab 1 atau download file gns3nya disini
- Aktifkan fungsi routing Ipv6 pada semua router
- Tambahkan Ipv6 pada semua interface router yang saling terhubung
- Tambahkan loopback Ipv6 pada semua router
- Aktifkan routing IS-IS untuk Ipv6
Verifikasi Lab :
- Pastikan semua loopback router Ipv4 dan Ipv6 dapat di ping.
- Cek routing tabel Ipv4 dan Ipv6.
- Lakukan traceroute ke loopback Ipv4 dan Ipv6 pada R3.
- Cek IS-IS databasenya.
Konfigurasi
Gunakan konfigurasi pada Lab 1, kemudian tambahkan konfigurasi sebagai berikut.
Router R1
R1#conf t
R1(config)#int lo0
R1(config-if)#ipv6 add 1::1/128 (menambahkan IPv6 pada interface)
R1(config-if)#int fa0/0
R1(config-if)#ipv6 add 12::1/120
R1(config-if)#ipv6 router isis (menambahkan routing ISIS untuk IPv6)
R1(config-if)#int lo0
R1(config-if)#ipv6 router isis
R1(config-if)#ex
R1(config)#ipv6 unicast-routing (mengaktifkan fitur IPv6 pada router)
Router R2
R2#conf t
R2(config)#int lo0
R2(config-if)#ipv6 add 2::2/128
R2(config-if)#ipv6 router isis
R2(config-if)#int fa0/0
R2(config-if)#ipv6 add 12::2/120
R2(config-if)#ipv6 router isis
R2(config-if)#int fa0/1
R2(config-if)#ipv6 add 23::2/120
R2(config-if)#ipv6 router isis
R2(config-if)#ex
R2(config)#ipv6 unicast-routing
Router R3
R3(config)#int lo0
R3(config-if)#ipv6 add 3::3/128
R3(config-if)#ipv6 router isis
R3(config-if)#int fa0/0
R3(config-if)#ipv6 add 23::3/120
R3(config-if)#ipv6 router isis
R3(config-if)#ex
R3(config)#ipv6 unicast-routing
Verifikasi
Lakukan ping ke semua IP loopback router, baik IPv4 maupun IPv6. Pastikan reply.

Cek routing tabelnya, baik Ipv4 dan Ipv6

Terlihat IPv4 dan IPv6 keduanya bisa berjalan secara bersamaan.
Lihat database routing ISISnya untuk lebih memastikan IPv4 dan IPv6 telah berjalan secara bersamaan.
