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.
