•
Before adding an MBGP peer to an MBGP peer group, you must add the corresponding IPv4 unicast
peer to the IPv4 BGP peer group.

Configuring MBGP community
The community attribute can be advertised between MBGP peers in different ASs. Routers in the same
community share the same policy.
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.
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.
For routing policy configuration, see
Layer 3—IP Routing Configuration Guide
