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 attribute extensions that help
confine the scope of Optional attributes within a given AS or a given
BGP member-AS in Confederation
