    Monitoring LDP Interfaces

    Purpose

    Display information about all LDP interfaces or the specified LDP interface.

    Action

    To display information about all LDP interfaces:

    host1#show ldp interface
    Interface ATM6/0.120
        Interface address: 192.168.12.1/28
        Enabled with profile 'default'
        Configured hold time: 15
        Hello interval: 5
        Hold Time: 1
        242 hello received, 242 hello sent, 0 hello rejected
        1 adjacency created, 0 adjacency deleted, 
      Number of adjacencies = 1
        Link hello adjacency: Address: 10.10.12.2, Transport address: 80.0.2.2,
          Up for 00:20:09, Remaining hold time: 11 sec

    To display brief information about LDP interfaces:

    host1#show ldp interface brief
    Interface              IP-Address          Protocol 
    ATM6/1.1               192.168.100.21/30   enabled
    ATM6/1.3               192.168.100.17/30   enabled
    ATM6/1.5               192.168.100.13/30   enabled
    ATM6/0.7               172.16.100.1/30     enabled
    ATM6/0.8               172.16.100.22/30    enabled
    ATM6/0.9               172.16.100.14/30    enabled
