enable ospf [vlan [all | vlan-name] | area area-identifier |virtual-link router-identifier area-identifier] restart-helper-lsa-check

Description

Enables the restart helper router to terminate graceful OSPF restart when received LSAs would affect the restarting router.

Syntax Description

all Specifies all VLANs
vlan-name Specifies a VLAN name.
router-identifier Specifies the router ID of the remote router of the virtual link.
area-identifier Specifies an OSPF area.

Default

The default is enabled.

Usage Guidelines

This command configures the restart helper router to terminate graceful OSPF restart when received LSAs would affect the restarting router. This will occur when the restart-helper receives an LSA that will be flooded to the restarting router or when there is a changed LSA on the restarting router's retransmission list when graceful restart is initiated.

Example

The following command configures a router to terminate graceful OSPF restart for all routers in area 10.20.30.40 if it receives an LSA that would affect routing:

enable ospf area 10.20.30.40 restart-helper-lsa-check
