FRR version 7.3
commit Id: c0038fc
We have been trying to use FRR as BGP for 6VPE. The BGP sessions were up and also received 6VPE routes from PE routers (Cisco router), however the FRR didn't show these received routes as valid and best path.
The topology diagram :-
On the PE routers, we configured MP-BGP to exchange IPv6 prefixes and the LSP (Label Switched Path) is based on IPv4.
The BGP configuration used in FRR router (PE 2) is :-
router bgp 234
no bgp default ipv4-unicast
neighbor 2.2.2.2 remote-as 234
neighbor 2.2.2.2 update-source 4.4.4.4
!
address-family ipv6 vpn
neighbor 2.2.2.2 activate
exit-address-family
!
router bgp 234 vrf vrfipv6
no bgp default ipv4-unicast
neighbor 3333::5 remote-as 5
!
address-family ipv6 unicast
redistribute connected
neighbor 3333::5 activate
label vpn export 107
rd vpn export 234:1
rt vpn both 1:1
export vpn
import vpn
exit-address-family
!
Expected behavior
The routes received from PE router should be installed on the bgp table and rib table.
The BGP update sent from FRR router (PE 2) must have nexthop as IPv4 mapped IPv6 address.
