Determining the Refresh Reduction Capability of RSVP Neighbors

To determine the RSVP refresh reduction capability of an RSVP neighbor, you need the following information:

The RR bit advertised by the neighbor
The local configuration of RSVP refresh reduction
The actual RSVP messages received from the neighbor

To obtain this information, you can issue a show rsvp neighbor detail command. The following is a sample of output from this command:

user@host> show rsvp neighbor detail
