Purpose
Command or Action
Example:
RP/0/RP0/CPU0:router(config-ldp)#
neighbor
192.168.2.44:0 password secretpasswd
Configures the parameters for the LDP backoff mechanism. The
LDP backoff mechanism prevents two incompatibly configured
backoff initial maximum
Example:
RP/0/RP0/CPU0:router(config-ldp)#
backoff
10 20
Step 9
LSRs from engaging in an unthrottled sequence of session setup
failures. If a session setup attempt fails due to such incompatibility,
each LSR delays its next attempt (backs off), increasing the delay
exponentially with each successive failure until the maximum
backoff delay is reached.
commit
—
Saves the configuration changes and remains within the
configuration session.
Use the

(Optional)
Displays the status of the LDP session with its neighbors. This
command can be run with various filters as well as with the brief
option.
show mpls ldp neighbor
Example:
RP/0/RP0/CPU0:router#
show mpls ldp
neighbor
Step 11
(Optional)
Displays the status of the LDP session with its neighbors for the
specified VRF. This command can be run with the brief option.
show mpls ldp vrf vrf-name neighbor
Example:
RP/0/RP0/CPU0:router#
show mpls ldp vrf
red neighbor
Step 12
(Optional)
Displays the brief LDP session neighbor information for all VRFs.
show mpls ldp vrf all neighbor brief
Example:
RP/0/RP0/CPU0:router#
show mpls ldp vrf
all neighbor brief
Step 13
(Optional)
Resets an LDP session.
clear mpls ldp neighbor
