CSC topology using IGP+LDP on PE running XR
I am trying to setup CSC topology using IGP+LDP between PE and CE. Where PE is XR. I used eigrp as a routing protocol. I could not form mpls ldp nei between PE and CE.
I don't know exactly what is the correct configuration at PE(XR) side. My configuration of PE is as follow:
#PE
mpls ldp
router-id 9.9.0.11
interface GigabitEthernet0/1/0/0.112
!
interface GigabitEthernet0/1/0/1
no shutdown
!
router eigrp 65535
address-family ipv4
!
vrf ABC
address-family ipv4
default-metric 10000 1 255 255 1500
autonomous-system 10
redistribute bgp 111
interface Loopback1
!
interface GigabitEthernet0/1/0/1
!
At CE site, it is very simple, activating ldp at the interface using 'mpls ip'.
I could not find the command how to check mpls interface of vrf in XR. I can type only
> show mpls interface
This is not showing interface of vrf ABC, interface GigabitEthernet0/1/0/1. It is showing interfaces of global routing table (MPLS Core)
I also could not find vrf specific mpls ldp activation under 'mpls ldp'. I have to activate adding the interface directly.
Finally, it doesn't work. CE could not get ldp neighbor.
Anyone help me how to solve this issue. If I use BGP + label, XR is fine and working well. But, i am trying to setup IGP+LDP.
Comments
Only BGP is supported for label distribution for CSC.

Arr... Thank you so much for this information. So, I will judge, this will not be exam question. [:)]
