Configuring IPv6 MBGP Community
A peer group allows a group of peers to share the same policy, while a community allows 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 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 advertise the community attribute to an IPv6 MBGP peer/peer group:
