revised draft of BGP-4

[Yakov Rekhter <[e-mail]>]

Folks,

Today I sent to CNRI a revised version of BGP-4 spec.

The only difference between this version and the current protocol spec
(other than changing dates and my affiliation) are the following two
paragraphs:


First paragraph:

	If the OPEN message carries any other Optional Parameter (other than Authentication
	Information), and the local system doesn't recognize the Parameter, the
	Parameter shall be ignored.

Second paragraph:

	The information carried by the AS_PATH attribute is checked for
	AS loops. AS loop detection is done by scanning the full AS path
	(as specified in the AS_PATH attribute), and checking that the
	autonomous system number of the local system does not appear
	in the AS path. If the autonomous system number appears in the AS path
	the route may be stored in the Adj-RIB-In, but unless the router is
	configured to accept routes with its own autonomous system in the AS path, 
	the route shall not be passed to the BGP Decision Process. 
	Operations of a router that is configured to accept routes with its own autonomous
	system number in the AS path are outside the scope of this document.


Please comment on this document as soon as possible, since we are planning to advance
the document to a Full Standard at the Stockholm IETF.

Thanks.
