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 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).
ASN:NNNN Enter the 2-octet AS specific extended community number in the format ASN:NNNN (2-
byte AS number:4-byte community value).
IPADDR:NN Enter the IP address specific extended community in the format IPADDR:NN (4-byte IPv4
Unicast Address:2-byte community value).
additive (OPTIONAL) Enter the keyword additive to add to the existing extended community.
non-trans (OPTIONAL) Enter the keywords non-trans to indicate a non-transitive BGP extended
community.
Defaults none
