Greetings
I am trying to configure C2C with BGP as the PE-CE routing protocol and Static as the C to CE routing protocol.
The main issue am running now is the eBGP session (VPNv4) between the CEs , routes are delivered but there is no connectivity and hence the eBGP session is not coming up.
Per my understanding , the BGP should be labelled unicast between the PE (XRV 6.6.2) and the respective CE. Before i changed the BGP session from IPv4 unicast to labeled unicast it was working (CE to CE traffic) , when I moved to the C traffic , I had to change the BGP to labeled unicast.
C1 ? CE2 ? PE3 ? P4 ? P5 ? PE6 ? CE7 ? C8
PE3:
router bgp 100
address-family ipv4 unicast
!
address-family vpnv4 unicast
!
neighbor 10.1.100.6
remote-as 100
update-source Loopback0
address-family vpnv4 unicast
vrf CORE
rd 100:1
address-family ipv4 unicast
allocate-label all
!
neighbor 172.16.23.2
remote-as 10
address-family ipv4 labeled-unicast
route-policy ALLOW in
route-policy ALLOW out
CE2:
router bgp 10
bgp log-neighbor-changes
no bgp default ipv4-unicast
neighbor 10.1.100.7 remote-as 7
neighbor 10.1.100.7 ebgp-multihop 5
neighbor 172.16.23.3 remote-as 100
!
address-family ipv4
network 10.1.100.2 mask 255.255.255.255
neighbor 172.16.23.3 activate
neighbor 172.16.23.3 send-label
exit-address-family
!
address-family vpnv4
neighbor 10.1.100.7 activate
neighbor 10.1.100.7 send-community extended
exit-address-family
!
address-family ipv4 vrf CUST
redistribute static
exit-address-family
Nothing on the C except for a default route , is there anything I am missing? LDP is functioning well along the path.
Appreciated.
