[M/MX/T-series] Command to check the number of routes that are associated with each RSVP LSP

Article ID: KB25119 KB Last Updated: 26 Jun 2012Version: 1.0
Summary:
This article provides information about the CLI command to check the number of active routes that are associated with each RSVP LSP.
Symptoms:
The CLI command to check the number of active routes that are associated with each RSVP LSP.
Cause:
 
Solution:
The show mpls lsp and show rsvp session commands have the Rt counter, which displays the number of active routes that are using a particular LSP as a next-hop.

The command to check this Rt counter was changed via PR 611292. With this PR fix, you now need the count-active-routes knob to display the number of active routes against the Rt counter. The versions with this PR fix will no longer show the number of active routes with just the show mpls lsp or show rsvp session commands. 

The following sample shows Junos CLI output with and without count-active-routes on Junos 10.4R9, which has fix for PR 611292.
