Traceroute MPLS IPv4
This window is used for hop-by-hop fault localization as well as path tracing the LSP of the specified FEC. If there is
no LSP for the specified FEC, the “Destination unreachable” message will be displayed. Otherwise, MPLS echo
request messages will be sent out to along the LSP of the specified FEC. The TTL in the outmost label of the MPLS
echo requests is set successively to 1, 2, 3, and so on. It forces the echo request expired at each successive LSR
along the LSP. The LSR returns an MPLS echo reply. If the sender cannot receive a reply before the timeout, the
trace route will stop.
To view the following window, click MPLS > Traceroute MPLS IPv4, as shown below:
