Configuring a Large Scale MBGP Network
Prerequisites
Before configuring this task, you need to 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 due to large numbers of
MBGP peers. You can configure peer groups to make management easier and improve route
distribution efficiency.
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.
z
To configure an MBGP peer group, you need to enable the corresponding IPv4 BGP unicast peer
group in IPv4 MBGP address family view.
z
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:
