What are two services that the OSPF Hello protocol provides? A. It discovers neighbor routers ..

Answer / guest

Answer: A and C

The Hello protocol is used for establishing and maintaining
router neighbor relationships. Hello packets are used for
neighbor discovery and recovery. They also indicate that a
client is still operating and network ready through
keep-alives. On multiaccess networks (networks supporting
more than two routers), the Hello protocol elects a
designated router and a backup designated router.
