Inspecting VCs
On a MPLS L2VPN network, you can use the MPLS LSP ping function to test the VC connectivity and get
necessary information for troubleshooting VC failures.
On the local PE, the MPLS LSP ping function adds the label of the VC to be tested into MPLS Echo Request
messages so the messages will travel along the VC. The local PE determines whether the VC is valid and
reachable according to the replies received from the peer PE.
To test the VC connectivity, perform the following task in any view:
Task Command Remarks
Use MPLS LSP ping to check VC
connectivity.
ping lsp [ -a source-ip | -c count |
-exp exp-value | -h ttl-value | -m
wait-time | -r reply-mode | -s
packet-size | -t time-out | -v ] * pw
ip-address pw-id pw-id
Applicable only to Martini VCs.
