Use of OSI IS-IS for Routing in TCP/IP and Dual Environments
Status of this Memo
This RFC specifies a protocol on the IAB Standards Track for the
Internet community, and requests discussion and suggestions for
improvements. Please refer to the current edition of the "IAB
Official Protocol Standards" for the standardization state and status
of this protocol. Distribution of this memo is unlimited.
This RFC is available in both postscript and text versions. Where
possible, use of the postscript version is recommended. For example,
this text version may have figures which are less informative or
missing.
Abstract
This RFC specifies an integrated routing protocol, based on the OSI
Intra-Domain IS-IS Routing Protocol, which may be used as an interior
gateway protocol (IGP) to support TCP/IP as well as OSI. This allows
a single routing protocol to be used to support pure IP environments,
pure OSI environments, and dual environments. This specification was
developed by the IS-IS working group of the Internet Engineering Task
Force.
The OSI IS-IS protocol has reached a mature state, and is ready for
implementation and operational use. The most recent version of the
OSI IS-IS protocol is contained in ISO DP 10589 [1]. The proposed
standard for using IS-IS for support of TCP/IP will therefore make
use of this version (with a minor bug correction, as discussed in
Annex B). We expect that future versions of this proposed standard
will upgrade to the final International Standard version of IS-IS
when available.
Comments should be sent to "isis@merit.edu".
