Configuring a large scale MBGP network
Configuration prerequisites
Before performing this task, make peering nodes accessible to each other at the network layer.
Configuring IPv4 MBGP peer groups
In a large-scale network, configuration and maintenance become difficult because of large numbers of
MBGP peers. You can configure peer groups to make management easier and to improve the efficiency
of route distribution.
Follow these steps to configure an IPv4 MBGP peer group:
To do… Use the command… Remarks
Enter system view system-view
—
Enter BGP view bgp as-number
—
Create a BGP peer group
group group-name [ external |
internal ]
Required
Not created by default.
Add a peer into the peer group
peer ip-address group group-
name [ as-number as-number ]
Required
No peer is added by default.
Enter IPv4 MBGP address family
view
ipv4-family multicast
—
Enable the IPv4 unicast peer
group
peer group-name enable Required
Add an IPv4 MBGP peer to the
peer group
peer ip-address group group-
name
Required
Not configured by default
CAUTION:
To configure an MBGP peer group, you must enable the corresponding IPv4 BGP unicast peer group
in IPv4 MBGP address family view.
Before you add 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, define extended community attributes as needed.
Follow these steps to configure MBGP community:
