Hello All,
I'm trying to configure a Backbone running MPLS and BGP .. I've been able to establish MPLS between the routers. The PELeft and PERight will be connected to end routers where the end routers will be in separate VRFs (2 to be exact).
I have reachability between all the routers. I'm running OSPF in the Backbone between the 3 Routers, and BGP between PELeft and PERight.
Here are the configuration of the 3 Routers:
PELeft:
interface Loopback0
ip address 1.1.1.1 255.255.255.255
!
interface Serial0/0
ip address 10.10.10.2 255.255.255.0
mpls ip
clock rate 2000000
!
router ospf 1
log-adjacency-changes
network 1.1.1.1 0.0.0.0 area 0
network 10.10.10.0 0.0.0.255 area 0
!
router bgp 13879
bgp log-neighbor-changes
neighbor 2.2.2.2 remote-as 13879
!
address-family ipv4
neighbor 2.2.2.2 activate
no auto-summary
no synchronization
exit-address-family
CorePRouter:
interface Serial0/0
ip address 10.10.10.1 255.255.255.0
mpls ip
clock rate 2000000
!
router ospf 1
log-adjacency-changes
network 10.10.10.0 0.0.0.255 area 0
network 10.10.20.0 0.0.0.255 area 0
PERight:
interface Loopback0
ip address 2.2.2.2 255.255.255.255
!
interface Serial0/0
ip address 10.10.20.2 255.255.255.0
mpls ip
clock rate 2000000
!
router ospf 1
log-adjacency-changes
network 2.2.2.2 0.0.0.0 area 0
network 10.10.20.0 0.0.0.255 area 0
!
router bgp 13879
bgp log-neighbor-changes
neighbor 1.1.1.1 remote-as 13879
!
address-family ipv4
neighbor 1.1.1.1 activate
no auto-summary
no synchronization
exit-address-family
And for the reachability:
PERight#ping 1.1.1.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 1.1.1.1, timeout is 2 seconds:

But the BGP between the PERight and PELeft is not coming up
PERight#sh ip bgp summ | b N
Neighbor V AS MsgRcvd MsgSent TblVer InQ OutQ Up/Down State/PfxRcd

PELeft#sh ip bgp summ | b N
Neighbor V AS MsgRcvd MsgSent TblVer InQ OutQ Up/Down State/PfxRcd
2.2.2.2 4 13879 0 0 0 0 0 never Active
What am I missing here?
