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. set extcommunity rt To set Route Origin community attributes in Route Map, use this feature. Syntax set extcommunity rt {as4 ASN4:NN [non-trans] | ASN:NNNN [non-trans] | IPADDR:NN [non-trans]} [additive] To delete the Route Origin community, use the no set extcommunity command. Parameters as4 ASN4:NN ASN:NNNN IPADDR:NN additive non-trans Enter the keyword as4 then the 4-octet AS specific extended community number in the format ASN4:NN (4-byte AS number:2-byte community value). Enter the 2-octet AS specific extended community number in the format ASN:NNNN (2byte AS number:4-byte community value). Enter the IP address specific extended community in the format IPADDR:NN (4-byte IPv4 Unicast Address:2-byte community value). (OPTIONAL) Enter the keyword additive to add to the existing extended community. (OPTIONAL) Enter the keywords non-trans to indicate a non-transitive BGP extended community.
