Description
helper mode, or only helper mode. LDP graceful restart and helper mode are both
disabled by default. The no version disables both LDP graceful restart and helper
mode.
Graceful restart causes the fault tolerant session TLV to be included in LDP initialization
messages with a nonzero value for the reconnect timeout. This action announces to
neighbors that the router preserves its forwarding state cross a restart.
Helper mode causes the fault tolerant session TLV to be included in LDP initialization
messages. The reconnect timeout value in the TLV is zero when LDP graceful restart
is disabled. This TLV announces to neighbors that the router preserves any label-FEC
mapping it has received from a neighbor in the event that the neighbor performs an
LDP graceful restart.
Options
