EoMPLS between Cisco 7604 and ASR 9000

Dear collegues

We have Cisco  7604 and ASR 9000 connected together via 10GE interface. Our 7604 has  ES+ core-facing module and not ES+ on AC side. 

We are implementing EoMPLS between them but VC doesn't come up.

Does anyone have some consideration about what the problem is?

We have following connections:

Catalyst 3750 <---->  Ge 1/2 Cisco 7604 TE 4/4 <----> Te0/0/0/0 ASR9000 Te0/0/0/1 <----> ME 3600

Here is the output os show ... command

EoMPLS between Cisco 7604 and ASR 9000


In addition to these commands, you should review the MPLS Label (Outer Label) assigned by the MPLS network to the Xconnect  to determine if it is using LDP or if is using a TE-Tunnel,  MLS CEF (on the 7600) and the output of debug commands for the xconnect.

Note: Depending on the amount of Xconnects in your network, it's recommended to perform conditional debugging to limit the amount of debug data (i.e. debug interface Te4/4, followed by specific debug commands).

On the 7600:

- show mpls forwarding table | i 16002

- show mls cef mpls labels 16002

- show mls cef adjacency entry 16002 detail

- debug interface Te4/4

- debug mpls l2transport vc status event

- debug mpls l2transport vc status fm

EoMPLS between Cisco 7604 and ASR 9000

Rurick, thank you for your answer!

We solved the problem.

I used static routing to reach loopbacks, and when I configured OSPF between 7604 and asr9k VC came up.
