Verifying that the RSVP-Signaled LSP Is Carrying Traffic

Table of contents:

Problem

You want to know that traffic is actually using an RSVP-signaled LSP that youve configured.

Solution

Look at the LSP traffic statistics:

	aviva@R3> show 
mpls lsp statistics transit
	Transit LSP: 2 sessions
	To From State Packets Bytes LSPname
	10.0.0.1 10.0.0.6 Up 0 0 R6-to-R1
	10.0.0.6 10.0.0.1 Up 25 2400 R1-to-R6
	Total 2 displayed, Up 2, Down 0

Discussion

To make sure that traffic is using the LSP, look at the traffic statistics. This recipe shows the show mpls lsp statistics commands. You can also use the show rsvp session statistics command to get the same output.

The Packets column shows the number of packets that have followed a particular LSP, and the Bytes column gives the total byte count of all the packets. In this recipe, LSP R1-to-R6 has carried 25 packets, for a total of 2,400 bytes.
