Configuring MBGP community
The COMMUNITY attribute can be advertised between MBGP peers in different ASs. Routers in the same
community share the same policy.
When you configure MBGP community, you must reference a routing policy to define the specific
COMMUNITY attributes, and apply the routing policy for route advertisement.
You can reference a routing policy to modify the COMMUNITY attribute for routes sent to a peer. In
addition, you can define extended community attributes as needed. For routing policy configuration, see
Layer 3—IP Routing Configuration Guide.
