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: Figure 11-25 Traceroute MPLS IPv4 Window 574
