Choosing a "Common IGP" for the IP Internet

(The IESG's Recommendation to the IAB)

Status of this Memo

This memo provides information for the Internet community. It does

not specify an Internet standard. Distribution of this memo is

unlimited.

Special Note

This document was originally prepared as an Internet Engineering

Steering Group (IESG) recommendation to the Internet Architecture

Board (IAB) in mid-summer 1991, reaching the current version by the

date shown above. Although the document is now somewhat dated (e.g.,

CIDR and RIP II are not mentioned), the IESG felt it was important to

publish this along with the recent OSPF Applicability Statement [11]

to help establish context and motivation.

Abstract

This memo presents motivation, rationale and other surrounding

background information leading to the IESG's recommendation to the

IAB for a single "common IGP" for the IP portions of the Internet.

In this memo, the term "common IGP" is defined, the need for a common

IGP is explained, the relation of this issue to other ongoing

Internet Engineering Task Force (IETF) routing protocol development

is provided, and the relation of this issue to the goal for multi-

protocol integration in the Internet is explored.

Finally, a specific IGP is recommended as the "common IGP" for IP

portions of the Internet -- the Open Shortest Path First (OSPF)

routing protocol.

The goal of this recommendation is for all vendors of Internet IP

routers to make OSPF available as one of the IGP's provided with

their routers.
