BGP Extended Communities (RFC 4360)
BGP Extended Communities, as defined in RFC 4360, is an optional transitive BGP attribute.
BGP Extended Communities provides two major advantages over Standard Communities:
● The range is extended from 4-octet (AA:NN) to 8-octet (Type:Value) to provide enough number communities.
● Communities are structured using a new “Type” field (1 or 2-octets), allowing you to provide granular control/filter routing
information based on the type of extended communities.
