Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Which protocol is supported when OSPFv2 is used as the routing protocol?

A	NetBios
B	LAT
C	IPv4
D	IPv6

Explanation:

Detailed explanation-1: -OSPFv2 is a classless routing protocol that permits the use of VLSMs and classless interdomain routing (CIDR). With Cisco routers, OSPF also supports equal-cost multipath load balancing and neighbor authentication. OSPF uses multicast addresses to communicate between routers. OSPF uses IP protocol 89.

Detailed explanation-2: -Open Shortest Path First Version 2 (OSPFv2) is a link-state routing protocol that uses link-state advertisements (LSAs) to update neighboring routers about a router’s interfaces. Each router maintains an identical area-topology database to determine the shortest path to any neighboring router.

Detailed explanation-3: -OSPF Packets OSPF routers communicate using IP packets. OSPF messages ride directly inside of IP packets as IP protocol number 89.

Detailed explanation-4: -OSPF supports Internet Protocol Version 4 (IPv4) and Internet Protocol Version 6 (IPv6) networks and supports the Classless Inter-Domain Routing (CIDR) addressing model.
