Configuring BGP community

By default, a router does not advertise the COMMUNITY or extended community attribute to its
peers or peer groups. When the router receives a route carrying the COMMUNITY or extended
community attribute, it removes the attribute before advertising the route to other peers or peer
groups.
Perform this task to enable a router to advertise the COMMUNITY or extended community attribute
to its peers for route filtering and control. You can also use a routing policy to add or modify the
COMMUNITY or extended community attribute for specific routes. For more information about
routing policy, see
