Usage guidelines
GR enables an LSR to retain MPLS forwarding entries during an LDP restart, ensuring continuous MPLS
forwarding.
The graceful-restart command does not take effect for LDP sessions established before the command is
executed. To apply the new setting, execute the reset mpls ldp command to re-establish LDP sessions.
Examples
# Enable GR for LDP.
<Sysname> system-view
[Sysname] mpls ldp
[Sysname-ldp] graceful-restart

graceful-restart timer
Use graceful-restart timer to configure the MPLS Forwarding State Holding timer and the Reconnect timer
for GR.
Use undo graceful-restart timer to restore the default.
