Which statement is true about the difference between OSPFv2 and OSPFv3?
- OSPFv3 routers use a different metric than OSPFv2 routers use.
- OSPFv3 routers use a 128 bit router ID instead of a 32 bit ID.
- OSPFv3 routers do not need to elect a DR on multiaccess segments.
- OSPFv3 routers do not need to have matching subnets to form neighbor adjacencies.
Answers Explanation & Hints:
Because OSPFv3 routers form neighbor adjacencies by using the link-local address of the interface, they are not required to have global addresses configured on the interfaces. Even if they do have global addresses configured, the addresses do not have to be in the same subnet on each end of the link.
