What It Means

The sample output shows the tracing information in the rsvp-log file. The first entry shows that the log file was cleared, and the second entry shows that tracing is going to the rsvp-log file in the /var/log/ directory.

The log file displays a Path message that was sent from R1 to R5, and another that R1 received from R5, indicating that the two unidirectional LSPs between R1 and R5 are established. For more information about Path messages, see Examining RSVP Log Messages.
