Task Conguration example
Disabling graceful-restart-helper on a device
device(config-ospf6-router)#graceful-restart
helper disable
NOTE
Graceful restart for OSPFv3 helper mode is enabled by
default.
Enabling graceful-restart-helper on a device
device(config-ospf6-router)#no graceful-restart
helper disable
Enabling LSA checking option on the helper
device(config-ospf6-router)#graceful-restart
helper strict-lsa-checking
Enabling graceful-restart-helper per VRF
NOTE
Graceful-restart-helper option can be enabled or disabled per
VRF in OSPFv3. If congured outside VRF, then it is
applicable to the default VRF instance of OSPFv3.
device(config-ospf6-router-vrf-red)#graceful-
restart helper strict-lsa-checking
Conguring OSPFv3 Non-stop routing (NSR)
In graceful restart, the restarting neighbors need to help build the routing information during the failover, but the graceful restart helper
may not be supported by all devices in a network. Hence to eliminate this dependency, the non-stop routing (NSR) feature is supported
on Brocade devices. NSR does not require support from neighboring devices to perform hitless failover. NSR does not support IPv6-
over-IPv4 tunnel and vitual link, so trac loss is expected while performing hitless failover.
To enable NSR for OSPFv3, use the nonstop-routing command in the OSPFv6 interface mode.
device(config)# ipv6 router ospf
device(config-ospf6-router)# nonstop-routing
To disable NSR for OSPFv3, use the no form of the nonstop-routing command.
Syntax: [no] nonstop-routing
