Verifying and Troubleshooting MPLS Connectivity
In IP networks, you can use the ping and traceroute commands to verify network
connectivity and find broken links or loops . In an MPLS-enabled network, you can
use the mpls ping and trace mpls commands to detect plane failures in different
types of MPLS applications and network topologies.
Tasks to verify and troubleshoot connectivity in IP and MPLS-enabled networks are:
â– Sending an MPLS Echo Request Packet to an IP or IPv6 Address on page 368
â– Tracing the Path of an MPLS Echo Request Packet to an IP or IPv6
Address on page 368
â– Sending an MPLS Echo Request Packet to a Martini Circuit on page 368
â– Tracing the Path of an MPLS Echo Request Packet to a Martini Circuit on page 368
