LDP Graceful Restart Helping and Restarting Router Example
If the restarting router, Router X, was the Designated Router (DR) on network segment S when the help-
ing relationship began, the helper neighbor, Router Y, maintains Router X as the DR until the helping rela-
tionship is terminated. If there are multiple adjacencies with the restarting Router X, Router Y will act as a
helper on all other adjacencies.
Note. See “Configuring LDP Graceful Restart” on page 10-29 for more information on configuring grace-
ful restart.
