Step 5: Check the RSVP Log File on the Egress Router

Purpose

After placing an RSVP tracing configuration on router R5 similar to that on routers R3 and R6, display the RSVP log file for useful information about the problem on router R5. For steps to configure RSVP tracing, see Enable RSVP Tracing on Transit Routers.

Action

To check the RSVP log file, enter the following JUNOS CLI operational mode command:

user@host> show log rsvp-log

Sample Output

user@R5> show log rsvp-log 

Jul 21 10:53:16 R5 clear-log[40071]: logfile cleared

Jul 21 11:02:37 trace_on: Tracing to "/var/log/rsvp-log" started

Jul 21 11:03:07 RSVP error, send to DISABLED interface? Hello New 
10.1.56.1->10.1.56.2 Len=8 so-0/0/0.0

What It Means

The sample output shows that R5 did not receive the Path message because of a disabled interface, so-0/0/0.0.
