Disabling LDP Graceful Restart or Helper Mode

To disable LDP graceful restart and recovery, include the disable statement:



ldp {



graceful-restart {

disable;
}


}

For a list of hierarchy levels at which you can include this statement, see the statement summary section for this statement.

You can disable helper mode at the LDP protocols level only. You cannot disable helper mode for a specific routing instance. To disable LDP helper mode, include the helper-disable statement:



ldp {



graceful-restart {

helper-disable;
}


}

For a list of hierarchy levels at which you can include this statement, see the statement summary section for this statement.

The following LDP graceful restart configurations are possible:

LDP graceful restart and helper mode are both enabled.
LDP graceful restart is disabled but helper mode is enabled. A router configured in this way cannot restart gracefully but can help a restarting neighbor.
LDP graceful restart and helper mode are both disabled. The router does not use LDP graceful restart or the graceful restart TLV sent in the initialization message. The router behaves as a router that cannot support LDP graceful restart.

A configuration error is issued if you attempt to enable graceful restart and disable helper mode.
