LAB: OSPF Graceful Restart

He're you'll experimenting with an application that uses OSPF Type 9 LSAs -- Graceful Restart.

Note: The experience you'll get on this lab will vary greatly depending on your hardware. On a router running in a Virtual Machine, or a sofware driven router like a J-Series you don't have much separation between the forwarding plane and the control plane -- so you won't see to much effect. These routers are perfectly capable of helping others restart though! For the full effect, you need a pair of routers that have complete separation between the control plane and the forwarding plane like an M, MX or T series router.

  1. Enable graceful restart on your router.
  2. Configure your router not to abort the graceful restart process if there is an LSA change on the network.
  3. Check that your router is supporting graceful restart for the OSPF process.
  4. Reboot your router and set the timers on the OSPF process long enough that your router will have time to bring it's control plane up in the event of an unplanned outage.
  5. Set your router to be mean and not help anybody!
