This section lists references of OSPF.

The following table lists the references that apply in this chapter.




RFC 1587

This document describes a new optional type of OSPF area, referred to humorously as a "not-so-stubby" area (or NSSA). NSSAs are similar to the existing OSPF stub area configuration option, but have the additional capability to import AS external routes on a limited basis.


RFC 1765

Proper operation of the OSPF protocol requires that all OSPF routers maintain an identical copy of the OSPF link-state database. However, when the size of the link-state database becomes very large, some routers might be unable to store the entire database due to resource shortages. This condition is called "database overflow".

This RFC is experimental and non-standard.

RFC 2328

This memo documents version 2 of the OSPF protocol.


RFC 2370

This memo defines enhancements to the OSPF protocol to support a new class of link-state advertisements (LSA) called Opaque LSAs. Opaque LSAs provide a generalized mechanism to allow for future extensibility of OSPF.


RFC 3137

This memo describes a backward-compatible technique that can be used by OSPF (Open Shortest Path First) implementations to advertise unavailability to forward transit traffic or to lower the preference level for the paths through such a router.

This RFC is informational and non-standard.

RFC 3623

This memo documents an enhancement to the OSPF routing protocol, whereby an OSPF device can stay on the forwarding path even as its OSPF software is restarted.


RFC 3630

This document describes extensions to the OSPF protocol version 2 to support intra-area Traffic Engineering (TE), using Opaque Link State Advertisements.


RFC 3682

This document describes the use of a packets Time to Live (TTL) (IPv4) or Hop Limit (IPv6) to protect a protocol stack from CPU-utilization based attacks, which has been proposed in many settings.

This RFC is experimental and non-standard.

RFC 3906

This document describes how conventional hop-by-hop link-state routing protocols interact with new Traffic Engineering capabilities to create Interior Gateway Protocol (IGP) shortcuts.


RFC 4576

This document specifies the necessary procedure, using one of the options bits in the LSA (Link State Advertisements) to indicate that an LSA has already been forwarded by a PE and should be ignored by any other PEs that see it.


RFC 4577

This document extends that specification by allowing the routing protocol on the PE/CE interface to be Open Shortest Path First (OSPF) protocol.


RFC 4750

This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in TCP/IP-based Internet networks. In particular, it defines objects to manage version 2 of the Open Shortest Path First Routing Protocol. Version 2 of the OSPF protocol is specific to the IPv4 address family.
