match extcommunity
set extcommunity
You can specify one or more community values when you create an extended
community list. A clause in a route map that includes a list that has more than
one value matches only a route that has all of the values; that is, the multiple
values are logical ANDed.
Use the rt keyword to specify a route target community, which consists of one
or more routers that can receive a set of routes advertised by BGP that carry the
extended community attribute.
Use the soo keyword to specify a site-of-origin community, which consists of
one or more routers that inject into BGP a set of routes that carry the extended
community attribute.
Example
host1(config)#ip extcommunity-list boston1 permit rt 100:2 rt 100:3 rt 100:4
host1(config)#route-map marengo permit 10
host1(config-route-map)#match extcommunity boston1
A route matches this community list only if it belongs to at least all three
communities in extended community list boston1: communities 100:2, 100:3,
and 100:4.
Use the no version to remove a single extended community list entry if you
specify the permit or deny keyword and a path expression. Otherwise, the router
removes the entire community list.
See ip extcommunity-list.
Use to match an extended community list in a route map.
You can specify one or more extended community list names in a match clause.
If you specify more than one extended community list, the lists are logically
ORed.
Example
host1(config-route-map)#match extcommunity topeka10
Use the no version to remove the match clause from a route map or a specified
value from the match clause.
See match extcommunity.
Use to set the extended community attributes in a route map for BGP updates.
Use the rt keyword to specify a route target community, which consists of one
or more routers that can receive a set of routes advertised by BGP that carry the
extended community attribute.
Use the soo keyword to specify a site-of-origin community, which consists of
