OSPF Graceful Restart requires at least three routers as shown in
FIGURE 110
Before configuring graceful restart, use the show ip ospf neighbor command to determine the state
of the OSPF neighbors. For example,
BigIron RX# show ip ospf neighbor
Port
3/7
Enable graceful restart on each OSPF router in
Router 1
BigIron RX(config)#router ospf
BigIron RX(config-ospf-router)#graceful-restart
BigIron RX(config-ospf-router)#area 0
Router 2
BigIron RX(config)#router ospf
BigIron RX(config-ospf-router)#graceful-restart
BigIron RX(config-ospf-router)#area 0
Router 3
BigIron RX(config)#router ospf
BigIron RX(config-ospf-router)#graceful-restart
BigIron RX(config-ospf-router)#area 0
Use the show ip ospf neighbor command to display the state of the OSPF neighbors after enabling
graceful restart. For example,
