What would prevent two OSPF routers from forming an adjacency? (Choose two.)
What would prevent two OSPF routers from forming an adjacency? (Choose two.)
Two OSPF routers will not form an adjacency if they have different MTU sizes and different area types. OSPF requires the MTU size to match to ensure proper communication and data integrity, and it also requires that the routers be in the same area type to establish adjacency. Different router IDs and IP addresses do not prevent routers from forming adjacencies, as each router must have unique IDs and IP addresses by design.
