Usage guidelines

LDP GR enables an LSR to retain MPLS forwarding entries during an LDP restart, ensuring continuous MPLS forwarding.

The configuration of this command takes effect only on new LDP sessions. To apply the configuration to existing LDP sessions, you must reset the LDP sessions by using the reset mpls ldp command.

Examples

# Enable GR for LDP.
