Title : Constrain Attribute announcement within BGP Authors : Keyur Patel James Uttaro Bruno Decraene Wim Henderickx Filename : draft-keyupate-idr-bgp-attribute-announcement-00.txt Pages : 8 Date : 2015-10-18 Abstract: [RFC4271] defines four different categories of BGP Path attributes. The different Path attribute categories can be identified by the attribute flag values. These flags help identify if an attribute is optional or well-known, Transitive or non-Transitive, Partial, or of an Extended length type. BGP attribute announcement depends on whether an attribute is a well-known or optional, and whether an attribute is a transitive or non-transitive. BGP implementations MUST recognize all well-known attributes. The well-known attributes are always Transitive. It is not required for BGP implementations to recognise all the Optional attributes. The Optional attributes could be Transitive or Non-Transitive. BGP implementations MUST store and forward any Unknown Optional Transitive attributes and ignore and drop any Unknown Optional Non-Transitive attributes. Currently, there is no way to confine the scope of Path attributes within a given Autonomous System (AS) or a given BGP member-AS in Confederation. This draft defines two new attribute categories that help confine the scope of Optional attributes within a given AS or a given BGP member-AS in Confederation The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-keyupate-idr-bgp-attribute-announcement/ There's also a htmlized version available at: https://tools.ietf.org/html/draft-keyupate-idr-bgp-attribute-announcement-00 Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
