Using Ping/Tracert on an MPLS Network

Using Ping to Monitor Link Connectivity on an MPLS Network

Ping operations can be used to check the connectivity of label distribution protocol (LDP) label switched path (LSPs) that carry IPv4 or IPv6 packets and TE tunnels that carry IPv4 packets.

Using Tracert to Test the Forwarding Path on an MPLS Network

A tracert operation tests the path over which a label distribution protocol (LDP) label switched path (LSP) or a TE tunnel that carries IPv4 packets is established or locate the failure point on the path.

Using Ping to Check Link Connectivity on a P2MP MPLS Network

Run the ping commands to check the connectivity between nodes on a Point-to-Multipoint (P2MP) MPLS network.

Using Tracert to Check the Forwarding Path on a P2MP MPLS Network

Run the tracert commands to check path information on a Point-to-Multipoint (P2MP) MPLS network so that faults can be located.
