Check the RSVP Log File on the Egress Router
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.
To check the RSVP log file, enter the following Junos OS CLI operational mode command:
user@R5> show log rsvp-log Jul 21 10:53:16 R5 clear-log: 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
The sample output shows that R5 did not receive the Path message because of a disabled interface, so-0/0/0.0.
