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

Note: The mpls keyword is optional and is provided for compatibility with non–E-series implementations.
