Experience with the OSPF Protocol

RFC 1246                  Experience with OSPF                 July 1991


2.0  Documentation

Version 1 of the OSPF protocol is documented in RFC 1131 [1]. OSPF
Version 2, which supersedes Version 1, has been documented in RFC 1247
[2]. The differences between OSPF Version 1 and Version 2 are relatively
minor, and are listed in Appendix F of RFC 1247 [2]. All information
presented in this report concerns OSPF V2 unless explicitly mentioned
otherwise.

The OSPF protocol was developed by the OSPF Working Group of the
Internet Engineering Task Force. This Working Group has a mailing list,
ospf@trantor.umd.edu, where discussions of protocol features and
operation are held. The OSPF Working Group also meets during the
quarterly Internet Engineering Task Force conferences. Reports of these
meeting are published in the IETF's Proceedings. In addition, two
reports on the OSPF protocol have been presented to the IETF plenary
(see "Everything You Ever Wanted to Know about OSPFIGP" in [5] and "OSPF
Update" in [6]).

The OSPF protocol began undergoing field trials in Spring of 1990. A
mailing list, ospf-tests@seka.cso.uiuc.edu, was formed to discuss how
the field trials were proceeding. This mailing list is maintained by
Ross Veach of the University of Illinois [rrv]. Archives of this list
are also available. There has been quite a bit of discussion on the list
concerning OSPF/RIP/EGP interaction.

A OSPF V2 Management Information Base has also been developed and
published in [3]. For more information, see Section 3.0 of this report.

There is a free implementation of OSPF available from the University of
Maryland. This implementation was written by Rob Coltun [rcoltun].
Contact Rob for details.


3.0  MIB

An OSPF Management Information Base has been published in RFC 1248 [3].
The MIB was written by Rob Coltun [rcoltun] and Fred Baker [fbaker]. The
OSPF MIB appears on the mgmt subtree as SMI standard-mib 13.

The OSPF MIB was originally developed by Rob Coltun of the University of
Maryland, under contract to Advanced Computer Communications. A subset
of his proposal was implemented to facilitate their development, and
represents operational experience of a sort.

The MIB consists of a general variables group and ten tables:
