R3303-HP HSR6800 Routers MPLS Command Reference

46
For LDP sessions with MD5 authentication configured, give the LDP neighbor liveness time a greater value
so that the TCP connection can be reestablished.
Examples
# Set the LDP neighbor liveness time to 100 seconds.
<Sysname> system-view
[Sysname] mpls ldp
[Sysname-mpls-ldp] graceful-restart timer neighbor-liveness 100
graceful-restart timer reconnect
Use graceful-restart timer reconnect to set the FT reconnect time.
Use undo graceful-restart timer reconnect to restore the default.
Syntax

Default
The FT reconnect time is 300 seconds.
Views

Default command level
2: System level
Parameters
timer: Specifies the Fault Tolerance (FT) reconnect time in the range of 60 to 300 seconds.
Usage guidelines
The FT reconnect time refers to the maximum time that the stale flag will be preserved by the LSR after the
TCP connection fails.
Modifying the FT reconnect time will cause all LDP sessions and all LSPs based on the sessions to be
removed and then reestablished.
Examples
# Set the FT reconnect time to 100 seconds.
<Sysname> system-view
[Sysname] mpls ldp
[Sysname-mpls-ldp] graceful-restart timer reconnect 100
graceful-restart timer recovery
Use graceful-restart timer recovery to set the LDP recovery time.
Use undo graceful-restart timer recovery to restore the default.
