2.3.7 Checking the Configuration

After a local LDP session has been configured, you can view information about interfaces
enabled with MPLS and LDP, the LDP session status, LDP peers, and remote LDP peers.
Prerequisite
The configurations of a local LDP session are complete.

5. Run:
backoff timer init max
An Exponential backoff timer is configured. Note the following settings:
– init: specifies the initial value of an Exponential backoff timer. The value is an
integer ranging from 5 to 2147483, in seconds. The default value is 15.
– max: specifies the maximum value of an Exponential backoff timer. The value is
an integer ranging from 5 to 2147483, in seconds. The default value is 120.
NOTE
Setting the initial value equal to or greater than 15 and the maximum value equal to or greater
than 120 is recommended.
The backoff timer command helps the active role adjust the interval between attempts
to establish an LDP session.
– The initial and maximum values can be increased to allow a longer interval between
attempts to establish an LDP session during device upgrade.
– The initial and maximum values can be decreased to allow a shorter interval
between attempts to establish an LDP session if intermittent service interruptions
occur.
Run the display mpls interface [ interface-type interface-number ] [ verbose ] command
to check information about MPLS-enabled interfaces.
Run the display mpls ldp [ all ] [ verbose ] command to check LDP information.
Run either of the following commands to check information about LDP-enabled interfaces:
– display mpls ldp interface [ interface-type interface-number | verbose ]
– display mpls ldp interface [ all ] [ verbose ]
Run either of the following commands to check the LDP session status:
– display mpls ldp session [ verbose | peer-id ]
– display mpls ldp session [ all ] [ verbose ]
Run either of the following commands to check information about LDP peers:
– display mpls ldp peer [ verbose | peer-id ]
– display mpls ldp peer [ all ] [ verbose ]
