Command History
Usage Guidelines This command removes extended community attributes of an inbound or outbound Border Gateway
Pr
otocol (BGP) update using a route map to filter and determine the extended community attribute to be
deleted and replaced. Depending upon whether the route map is applied to the inbound or outbound
update for a neighbor, each extended community that passes the route map permit clause and matches
the given extended community list will be removed and replaced from the extended community attribute
being received from or sent to the BGP neighbor.
Examples The following example shows how to replace a route target 100:3 on an incoming update with a route
t
arget of 100:4 using an inbound route map extmap:
.

Router(config-af)# neighbor 10.10.10.10 route-map extmap in
.

Router(config)# ip extcommunity-list 1 permit rt 100:3

Router(config-route-map)# set extcomm-list 1 delete
