Also, OSPFv2 does not advertise IPv6 addresses. That's OSPFv3.

Selected Answer: AE
Two basics ways to enable OSPFv2 in an active interface are: 1) OSPFv2 Traditional configuration: R1(config)# router ospf <process-id> R1(config-router)# network <network-adddress> <wildcard-mask> area <area-number> 2) OSPv2 Interface configuration: R1(config)# interface gigabitEthernet 0/0 R1(config-router)# ip ospf <process-if> area <area-number> Where: R1 is the hostname of the router. As you can see, the "process-id" and the "area-number" are necessary parameters in both configurations, including the quad-zero configuration that is similar to the "Traditional" way.

The trick is that you need the Process ID to configure OSPF but for routers to become neighbors it is not needed. IPV4 is OSPF V2

Key word is "enable", this is not pertaining to adjacency with neighbors.

THAT IS IN CORRECT. they need an ip so they can be part of the DR/BDR process if they dont have a router id. (which is not one of the options) because "process id is only "locally" important.
