What is OSPF RFC?

OSPF is a link-state routing protocol. It is designed to be run internal to a single Autonomous System. From this database, a routing table is calculated by constructing a shortest- path tree.

Which networks are defined in OSPF?

OSPF addresses three classes of network (as listed in section 1.2 of RFC 2328): point-to-point, broadcast, and non-broadcast.

What are the OSPF packet types?

There are 5 Types of OSPF packets:

  • The Hello Packet :
  • The Database Description Packet :
  • The Link State Request packet :
  • The Link State Update packets:
  • The Link State Acknowledge packets:

What is the RFC number for OSPFv2?

RFC 7684
RFC 7684: OSPFv2 Prefix/Link Attribute Advertisement.

What are Rfcs in networking?

In the computer network engineering and design realm, a Request for Comments (RFC) is a memorandum published by the Internet Engineering Task Force (IETF) describing methods, behaviors, research, or innovations applicable to the working of the Internet, along with Internet-connected systems.

What are two basic OSPF network types?

OSPF can operate in two modes when dealing with non-broadcast networks: non-broadcast multi-access (NBMA) or point-to-multipoint.

Which OSPF network types are compatible?

The following list indicates which OSPF network types can communicate with one another:

  • Broadcast to Broadcast.
  • Non-broadcast to Non-broadcast.
  • Point-to-Point to Point-to-Point.
  • Broadcast to Non-broadcast Networks (adjust hello and dead timers)
  • Point-to-Point to Point-to-Multipoint Networks (adjust hello and dead timers)

Which OSPF packet contains the different types of link state advertisements?

Which OPSF packet contains the different types of link-state advertisements? Link-state update (LSU) packets contain different types of link-state advertisements (LSAs). The LSUs are used to reply to link-state requests (LSRs) and to announce new information.

What is the difference between OSPF LSA type 4 and 5?

Type 4 – Summary ASBR LSA: Other routers need to know where to find the ASBR. This is why the ABR will generate a summary ASBR LSA which will include the router ID of the ASBR in the link-state ID field. Type 5 – External LSA: also known as autonomous system external LSA: The external LSAs are generated by the ASBR.

What are the different types of requests for comments RFC?

There are four streams of RFCs: IETF, IRTF, IAB, and independent submission.
