at 25:23 you say that if 2 router have same Router ID they can form an adjacency. are you sure? Router ID Should be unique in OSPF.

Hi Mohammad, Thanks for comment ... Router ID can be a name, a number or an IP address Let suppose two router has configured with loopback0 with same IP address then router(OSPF) follows the below criteria to select router ID.... 1. Manual configuration of Router ID 2. Highest IP address on loopback 0 interface 3. Highest IP address on physical interface(Non-Loopback interface). so in this case router still form the adjacency by selecting the physical interface IP as a router ID.
