What is the difference between OSPFv2 and OSPFv3?

OSPFv2 stands for Open Shortest Path First version 2 and OSPFv3 stands for Open Shortest Path First version 3. OSPFv2 is the IPv4’s OSPF version, whereas OSPFv3 is the IPv6’s OSPF version. In OSPFv2, many OSPF instances per interface are not supported, whereas in OSPFv3, many OSPF instances per interface are supported.

What is Inter area and intra area in OSPF?

Intra Area routes are the “O” routes that you see in the routing table. These routes are routes that are in the same area. Inter-area routes are the “O IA” routes that are learned in different areas.

What is OSPF RFC?

OSPF is a TCP/IP routing protocol, designed to be used internal to an Autonomous System (in other words, OSPF is an Interior Gateway Protocol). Version 1 of the OSPF protocol was published in RFC 1131.

Is OSPF intra or inter?

Both Intra and Inter-Area routes are also called OSPF Internal routes, as they are generated by OSPF itself, when an interface is covered with the OSPF network command.

Is OSPFv3 compatible with OSPFv2?

Another similarity to the relationship of RIPng to RIPv2 is that OSPFv3 is not backward-compatible with OSPFv2. So if you want to use OSPF to route both IPv4 and IPv6, you must run both OSPFv2 and OSPFv3.

What are the features of OSPFv3?

OSPFv3 supports multi-process on a link….OSPFv3 and OSPFv2 are the same in the following aspects:

  • Network types and interface types.
  • Interface state machines and neighbor state machines.
  • LSDB.
  • Flooding mechanism.
  • Five types of packets: Hello, DD, LSR, LSU, and LSAck packets.
  • Route calculation.

What is inter area?

(geology) An area where the soil composition differs significantly from the surrounding region.

Is RFC a protocol?

IS-IS is an interior gateway protocol, designed for use within an administrative domain or network. This is in contrast to exterior gateway protocols, primarily Border Gateway Protocol (BGP), which is used for routing between autonomous systems (RFC 1930).

What is OSPFv3?

OSPFv3 is the Open Shortest Path First routing protocol for IPv6. It is similar to OSPFv2 in its concept of a link state database, intra- and inter-area, and AS external routes and virtual links.

What is OSPFv2 in networking?

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.
