Several protocols have been specified in the Routing Area of the IETF
using a common variant of the Backus-Naur Form (BNF) of representing
message syntax.  However, there is no formal definition of this
version of BNF.

There is value in using the same variant of BNF for the set of
protocols that are commonly used together.  This reduces confusion and
simplifies implementation.

Updating existing documents to use some other variant of BNF that is
already formally documented would be a substantial piece of work.

This document provides a formal definition of the variant of BNF that
has been used (that we call Routing BNF) and makes it available
for use by new protocols.  [STANDARDS TRACK]

This is now a Proposed Standard Protocol.
