Configuring BGP community

A BGP community is a group of destinations with the same characteristics. It has no geographical
boundaries and is independent of ASs.
You can configure a routing policy to define which destinations belong to a BGP community and then
advertise the COMMUNITY attribute to a peer or peer group.
You can apply a routing policy to filter routes advertised to or received from a peer or peer group
according to the COMMUNITY attribute, which helps simplify policy configuration and management.
For how to configure a routing policy, see
