show mpls rsvp neighbor
The show mpls rsvp neighbor command displays RSVP neighbors that were discovered dynamically
during the exchange of RSVP packets.
The RR and MsgID flags in this command show the ability of the neighbor to support Refresh
Reduction and Message IDs respectively.
The ‘MsgID’ field is set to YES in the following cases:
• This field is defaulted to YES initially.
• It is set to YES if the neighbor sends a message containing a Message ID.
• It is also set to YES if the remote MPLS interface is configured to send Message IDs to this
neighbor.
The ‘MsgID’ field is set to NO in the following cases:
• If the peer rejects a message (with a PathErr or ResvErr) because it contains a Message ID
object, then this field is set to NO.
If the neighbor sends a NACK to a Message ID object that we send and then subsequently sends a
Path or Resv message that does not contain a Message ID, then RSVP sets this field to NO. This
allows RSVP to inter-operate with devices that do not support Message IDs.
