Verifying The Configuration Of The Midpoint Routers - Cisco ASR 920 Series Configuration

Verifying the Configuration of MPLS Point-to-Multipoint Traffic Engineering
Use the show ip mroute command to verify that IP multicast traffic is being forwarded to the P2MP TE tunnel. In the
following example, the output shown in bold shows that Tunnel 1 is part of the outgoing interface list for multicast group
232.0.1.4 with a source address of 10.10.10.10:
Example:
Router# show ip mroute

Verifying the Configuration of the Midpoint Routers

At the midpoint router, use the following commands to verify that MPLS forwarding occurs. If the midpoint
router is branch router, you can also use show mpls forwarding-table labels command to display show
specific labels.
SUMMARY STEPS
1. enable
2. show mpls forwarding-table
DETAILED STEPS
Step 1 enable
Issue the enable command to enter privileged EXEC mode.
Step 2 show mpls forwarding-table
Use the show mpls forwarding-table command to show that MPLS packets are switched at the midpoint routers. For
example:
Example:
Router# show mpls forwarding-table
