MBGP is the extension of BGP. Many concepts and configuration fundamentals of 
BGP are also applicable in MBGP.

When configuring MBGP, it is necessary to run BGP before entering corresponding 
address family view and configuring relevant parameters for different extended 
applications.

When configuring the MBGP peer/peer group, configure the AS number of the 
peer/peer group in BGP view first and then enter the corresponding address family 
view to enable the peer/peer group relation of the application.

Part commands in BGP view also exist in MBGP address family view. However, 
when configured in MBGP address family view, these commands are only effective 
to corresponding applications.

Commands in MBGP address family view that are related to specific applications 
are not described in this chapter. For corresponding contents, refer to Part VII 
“Multicast” and Part VIII “MPLS”.

MBGP versatile configuration includes:

■

Configure the address family

■

Enable the peer group

After MBGP is introduced, IPv4 unicast address family view sometimes is used to 
indicate the normal BGP view.

Perform the following configurations in BGP view.

Execute the 

 form of the command to return to BGP view and delete 

corresponding MBGP extended application configuration.

To enable BGP peers to exchange routing information, it is necessary to activate a 
certain peer group under unicast address family, then add the peers existing under 
the unicast address family into the activated peer group.

Perform the following configurations in address family view.
