BGP Extended Communities (RFC 4360)
BGP Extended Communities, as dened 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” eld (1 or 2-octets), allowing you to provide granular control/lter routing
information based on the type of extended communities.
deny
To reject (deny) from the two types of extended communities, route origin (rt) or site-of-origin (soo), use this feature.
Syntax
deny {rt | soo} {as4 ASN4:NN | ASN:NNNN | IPADDR:NN}
To remove (delete) the rule, use the no deny {rt | soo} {as4 ASN4:NN | ASN:NNNN |
IPADDR:NN} command.
Parameters
rt Enter the keyword rt to designate a Route Origin community.
soo Enter the keyword soo to designate a Site-of-Origin community (also known as
Route Origin).
as4 ASN4:NN Enter the keyword as4 then the 4-octet AS specic extended community number
in the format ASN4:NN (4-byte AS number:2-byte community value).
ASN:NNNN Enter the 2-octet AS specic extended community number in the format
ASN:NNNN (2-byte AS number:4-byte community value).
IPADDR:NN Enter the IP address specic extended community in the format IPADDR:NN (4-
byte IPv4 Unicast Address:2-byte community value).
Defaults Not congured.
