Verifying the Configuration of the Tailend Routers

At the tailend router, use the following steps to verify that:
• MPLS forwarding occurs.
• IP multicast forwarding occurs.
You can also use the show ip mfib, showmpls traffic-eng destination list, and show mpls traffic-eng tunnels
dest-mode p2mp commands for verification.
SUMMARY STEPS
1. enable
2. show mpls forwarding-table
3. show ip mroute
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 labeled packets are forwarded from the tailend
router without any label.
Example:
Router# show mpls forwarding-table
Local Outgoing
Label Label
