To configure an MBGP peer group, you need to enable the corresponding IPv4 BGP unicast peer
group in IPv4 MBGP address family view.
Before adding an MBGP peer to an MBGP peer group, you need to 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 route policy to modify the community attribute for routes sent to a peer. In addition,
you can define extended community attributes as needed.
Follow these steps to configure MBGP community:
