BGP Label Unicast Cisco & Juniper

Beberapa hari kemarin, ada inter0perability antara Cisco dan Juniper dalam implementasi unified mpls (BGP carrying label) atau orang Juniper sering nyebut BGP Label Unicast (LU).

Saat itu, Cisco 7600 jadi client bagi RR domestiknya Juniper. Permasalahan yang terjadi adalah session bgp establish namun si Juniper tidak menerima community yang dilempar cisco. Sedangkan client-client yang Juniper nampak baik-baik saja.

Cisco –Juniper RR

Di cisco 7600 saya create ACL, route-map dan enable bgp send-label.

access-list 10 permit 1.1.1.1

route-map LOOPBACK

match ip address 10

set community 1001:1337

router bgp 1

neighbor 2.2.2.2 remote-as 1

neighbor 2.2.2.2 update-s loo0

address-family ipv4

neighbor 2.2.2.2 send-community both

neighbor 2.2.2.2 send-label

neighbor 2.2.2.2 route-map LOOPBACK out

#show ip bgp summ

#show ip bgp nei 2.2.2.2 advertise-route

….prefix 1

#show bgp 2.2.2.2

Nah, si Junos tetep gak terima. Ane bingung, kenapa ya? ada yang salah dengan konfignya?
