The first RSVP packet sent is a PathErr, which indicates that some type of error has<br />

occurred on the LSP. When RSVP clears the sessions, it sends two PathTear messages<br />

to tear down the session, one message to the interface link between 10.1.13.1<br />

and 10.1.13.2, and the second message to the link between the loopback addresses<br />

of the ingress router (10.0.0.1) and the egress router (10.0.0.6). As RSVP re-establishes<br />

the LSP, it exchanges Path and Resv messages. Once the RSVP session is set up again,<br />

RSVP exchanges periodic Hello messages. The information logged for the RSVP Path<br />

packets is similar to the show rsvp session detail command output:<br />

aviva@R1> show rsvp session detail<br />
