Verifying Label Distribution - Cisco 10000-2P2-2DC Software Configuration Manual

Chapter 3 Configuring Remote Access to MPLS VPN
To verify the connections between neighbors, enter any of the following commands in privileged EXEC
mode:
Command
Router# ping [protocol | tag] {host-name |
system-address}
Router# ping vrf vrf-name system-address
Router# debug mpls packet
Because debugging output is assigned high priority in the CPU process, it can render the system
Caution
unusable. For this reason, use debug commands only to troubleshoot specific problems or during
troubleshooting sessions with Cisco Systems technical support personnel. Moreover, it is best to use
debug commands during periods of lower network traffic and fewer users. Debugging during these
periods decreases the likelihood that increased debug command processing overhead will affect system
use.
Example 3-16 ping
Router# ping 10.10.10.6
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.10.10.6, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 56/56/60 ms
Example 3-17 ping vrf
Router# ping vrf vrf-1 192.168.1.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4/ ms

Verifying Label Distribution

To verify label distribution, enter any of the following commands in privileged EXEC mode:
Command
Router# show mpls forwarding-table
Router# show tag-switching tdp discovery
