Configuring Graceful Restart Options for LDP

You can configure the following optional statements at the [edit protocols ldp graceful-restart] hierarchy level:



[edit]
protocols {


ldp {



graceful-restart {

disable;

helper-disable;

maximum-neighbor-reconnect-time seconds;

maximum-neighbor-recovery-time seconds;

reconnect-time seconds;

recovery-time seconds;
}


}


}

The statements have the following effects on the graceful restart process:

To configure the amount of time required to reestablish a session after a graceful restart, include the reconnect-time statement; the range is 30 through 120 seconds. To limit the maximum reconnect time allowed from a restarting neighbor router, include the maximum-neighbor-reconnect-time statement; the range is 30 through 300 seconds.

To configure the amount of time that helper routers are required to maintain the old forwarding state during a graceful restart, include the recovery-time statement; the range is 120 through 1800 seconds. On the helper router, you can configure a statement that overrides the request from the restarting router and sets the maximum amount of time the helper router will maintain the old forwarding state. To configure this feature, include the maximum-neighbor-recovery-time statement; the range is 140 through 1900 seconds.

Note: The value for the recovery-time and maximum-neighbor-recovery-time statements at the [edit protocols ldp graceful-restart] hierarchy level should be approximately 80 seconds longer than the value for the restart-duration statement at the [edit routing-options graceful-restart] hierarchy level. Otherwise, a warning message appears when you try to commit the configuration.

To disable LDP graceful restart capability, include the disable statement. To disable LDP graceful restart helper capability, include the helper-disable statement.
