+ DESCRIPTION
+ "The MIB module for the BGP-4 protocol.
+
+ Copyright (C) The Internet Society (2006). This
+ version of this MIB module is part of RFC 4273;
+ see the RFC itself for full legal notices."
+
+ REVISION "200601110000Z"
+ DESCRIPTION
+ "Changes from RFC 1657:
+
+ 1) Fixed the definitions of the notifications
+ to make them equivalent to their initial
+ definition in RFC 1269.
+ 2) Added compliance and conformance info.
+ 3) Updated information for the values of
+ bgpPeerNegotiatedVersion, bgp4PathAttrLocalPref,
+ bgp4PathAttrCalcLocalPref,
+ bgp4PathAttrMultiExitDisc,
+ bgp4PathAttrASPathSegement.
+ 4) Added additional clarification comments where
+ needed.
+
+ 5) Noted where objects do not fully reflect
+ the protocol as Known Issues.
+ 6) Updated the DESCRIPTION for the
+ bgp4PathAttrAtomicAggregate object.
+ 7) The following objects have had their DESCRIPTION
+ clause modified to remove the text that suggested
+ (using 'should' verb) initializing the counter
+ to zero on a transition to the established state:
+ bgpPeerInUpdates, bgpPeerOutUpdates,
+ bgpPeerInTotalMessages, bgpPeerOutTotalMessages
+ Those implementations that still do this are
+ still compliant with this new wording.
+ Applications should not assume counters have
+ started at zero.
+
+ Published as RFC 4273."
