Configuring a large-scale BGP network
In a large network, the number of BGP connections is huge and BGP configuration and maintenance
are complicated. To simply BGP configuration, you can use the peer group, community, route
reflector, and confederation features as needed. For more information about configuring peer groups,
see "Configuring a BGP peer group."
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 reference a routing policy to add or modify the
COMMUNITY or extended community attribute for specific routes. For more information about
routing policy, see "Configuring routing policies."
