Additional Information
If the LSP changes, the label and interface information displayed when you issued the
ping
command continues to be used. You must configure MPLS at the
[edit protocols
mpls]
hierarchy level on the remote router or switch to ping an LSP terminating there.
You must configure MPLS even if you intend to ping only LDP forwarding equivalence
classes (FECs).
In asymmetric MTU scenarios, the echo response may be dropped. For example, if the
MTU from System A to System B is 1000 bytes, the MTU from System B to System A is
500 bytes, and the ping request packet size is 1000 bytes, the echo response is dropped
because the PAD TLV is included in the echo response, making it too large.
