2.2 Message Syntax
Message syntax is based on the BGP-4 specification [RFC4271].
The deviations from the BGP Communities Attribute specification [RFC1997] are:
-
The RFC section on "Well-known Communities" states, "The following communities have global significance and their operations shall be implemented in any community-attribute-aware BGP speaker": NO_EXPORT (0xFFFFFF01), NO_ADVERTISE (0xFFFFFF02), and NO_EXPORT_SUBCONFED (0xFFFFFF03). These community operations are not implemented.
