While doing the lab and configuring ospf, I learnt something new today. In OSPF RID for a router is loopback interface IP(the highest loopback IP). Even if you shut down the loopback interface, its IP will still be used as RID for OSPF. (Assuming there is no other loopback configured on the router) Great video again John
Even if you restart ospf process, RID won't change as it is setup only once when you configure #router ospf 1. Which is why always manually set RID. sorry off topic but I couldn't resist sharing this. I get to learn so much from building whole lab from scratch myself
