Enable IPv6 BGP Peer inter ASN on CISCO 7606


Ceritanya hari ini adalah hari yang cukup melelahkan, sejak dari siang  saya dan Pak Agus Awaludin dari  Universitas Indonesia mencoba melanjutkan perjuangan menyambungkan Jaringan INHERENT area Sumatera ke Ring INHERENT area Jawa. Layer 1 sudah terlebih dahulu terhubung kemarin malam.

Setelah menunggu beberapa saat akhirnya kita dapatkan  alokasi IP WAN Point-to-Point UNILA-UI  dari wakgeng Bos nya INHERENT yakni ITB, langsung deh kita eksekusi . modifikasi sedikit pada prefix peer BGP IPv4 nya sesuaikan dengan kepunyaan UI, kira kira penampakannya adalah sebagai berikut;

!
router bgp 65009
bgp log-neighbor-changes
 neighbor 2403:DA00:1:A::9 remote-as 18007
neighbor 2403:DA00:1:A::9 description UNILA-UI
 neighbor 167.205.188.197 remote-as 18007
 neighbor 167.205.188.197 description UNILA-UI

!
 address-family ipv4
redistribute connected
redistribute ospf 100 route-map DENY_PRIVATE_ADDRESS
neighbor 167.205.188.197 activate

!
 address-family ipv6
neighbor 2403:DA00:1:A::9 activate
neighbor 2403:DA00:1:A::9 soft-reconfiguration inbound

Untuk IPv6 terlebih dahulu diaktifkan fungsing IPv6 routing dengan perintah sebagai berikut;

IBRUNILA01(config)#ipv6 unicast-routing
IBRUNILA01(config)#ipv6 multicast-routing

terakhir dicek apakah AS Peer sudah berjalan dengan baik.
