Before adding an IPv6 MBGP peer to the IPv6 MBGP peer group, you must add the corresponding
IPv6 BGP unicast peer to the corresponding IPv6 BGP unicast peer group.

Configuring IPv6 MBGP community
A peer group enables a group of peers to share the same policy, and a community enables a group of
IPv6 MBGP routers in multiple ASs to share the same policy. The COMMUNITY attribute is
propagated among IPv6 MBGP peers and not restricted to AS boundaries.
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 required.
You must configure a routing policy to define the COMMUNITY attribute and apply the policy to
outgoing routes. For more information about routing policy configuration, see
