Configuring Mbgp Community - 3Com S7906E Configuration Manual

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:
To do...
Enter system view
Enter BGP view
Enter IPv4 MBGP address family
view
Advertise the
community
attribute to an
MBGP peer/peer
group
Apply a route policy to routes
advertised to an MBGP peer/peer
group
When configuring MBGP community, you need to reference a route policy to define the specific
community attributes, and apply the route policy for route advertisement.
For route policy configuration, refer to Route Policy Configuration in the IP Routing Volume.
