Configuring LDP FRR
LDP FRR is based on IP FRR, and is enabled automatically after IP FRR is enabled. For information
about configuring IP FRR, see Layer 3—IP Routing Configuration Guide.
Resetting LDP sessions
Changes to LDP session parameters take effect only on new LDP sessions. To apply the changes to
an existing LDP session, you must reset all LDP sessions by executing the reset mpls ldp
command.
