Monitoring RSVP Path State Control Blocks, Reservation State Control Blocks, or Sessions

Purpose

Display RSVP path state control blocks, reservation state control blocks, or session information about the virtual router to assist in debugging. A session can be any of the following:

ingress session—Originating on the router
egress session—Terminating on the router
transit session—Travelling through the router

Action

To display path state control blocks for an ingress session:

To display reservation state control blocks for an ingress session:

host1#show mpls rsvp rsb
  RSB: Timeout 157500 label 1/33
       Flags : InUse
               StyleConverted
