Displaying LDP-IGP synchronization information

In addition to configuration information, you can display the following LDP-IGP synchronization information.

Displaying LDP-IGP synchronization on a session

To display LDP-IGP synchronization, use the show mpls ldp session command. When the timers are running, the remaining time appears without a refresh as well as the static value of the timer.

device# show mpls ldp session 10.7.7.2 0
Peer LDP ID: 10.7.7.2:0, Local LDP ID: 10.1.7.1:0, State: Operational
  Adj: Link, Role: Passive, Next keepalive: 1 sec, Hold time left: 31 sec
  Keepalive interval: 6 sec, Max hold time: 36 sec
  Up time: 16 min 46 sec
  TCP connection: 10.1.7.1:646--10.7.7.2:9004, State: ESTABLISHED 
  Neighboring interfaces: Eth 2/2
  Next-hop addresses received from the peer:4
    10.1.1.14	10.1.2.14	10.3.4.5	10.7.7.2
  IGP Sync:
   Unrecognized Notification Capability: Local: On, Remote: On
   Local State: In-sync, RemoteState: In-sync
   Rx label silence time: 1000 ms, Timer not running
  Graceful restart: enabled
    Peer reconnect time(msec): 120000, peer recovery time(msec): 0
    State: not started   

Displaying whether LDP-IGP synchronization is enabled on the interface

To display whether LDP-IGP synchronization is enabled on the interface, use the show mpls ldp interface command.

device# show mpls ldp int e2/16 
e2/16, label-space ID: 0
  Nbr count: 1
  Hello interval: 5 sec, next hello: 2 sec
  Hello timeout: 15 sec
  Current IGP Sync state: In Sync

Displaying the current cached LDP-IGP synchronization state

To display the current cached LDP-IGP synchronization state, use the show mpls interface command.

device# show mpls int e2/2
