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.
