configure ospf restart

configure ospf restart [none | planned | unplanned | both]

Description

Configures the router as a graceful OSPF restart router.

Syntax Description

none Do not act as a graceful OSPF restart router.
planned Only act as a graceful OSPF restart router for planned restarts.
unplanned Only act as a graceful OSPF restart router for unplanned restarts.
both Act as a graceful OSPF restart router for both planned and unplanned restarts.

The default is none.

Usage Guidelines

This command configures the router as a graceful OSPF router. When configured for planned restarts, it will advertise Grace-LSAs before restarting (for example, during an upgrade of the OSPF module). When configured for unplanned restarts, it will advertise Grace-LSAs after restarting but before sending any Hellos. When configured for both, the router will advertise restarting regardless of whether the restart was planned or unplanned.

Example

The following command configures a router to perform graceful OSPF restarts only for planned restarts:

configure ospf restart planned
