7.3.3 Configuring Inter-AS MSDP Peers on MBGP Peers
You can configure an MSDP peer relationship between RPs in different ASs that have set up an
MBGP peer relationship. In this manner, PIM-SM domains in different ASs can share multicast
source information.
Context
Establish the MBGP peer relationship between two RPs of different ASs and do as follows on
the MBGP peers:
NOTE
If the two RPs set up the BGP peer relationship, it is not necessary to set up the MBGP peer relationship
between them.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
msdp [ vpn-instance vpn-instance-name ]
MSDP is enabled in the public network instance or VPN instance, and the MSDP view is
displayed.
Step 3 Run:
peer peer-address connect-interface interface-type interface-number
An MSDP peer connection is configured.
The parameters of the command are explained as follows:
l peer-address: specifies the address of a remote MSDP peer. The address is the same as that
of the remote BGP or MBGP peer.
l interface-type interface-number: specifies the local interface connected to the remote MSDP
peer. The interface is the same as the local BGP or MBGP interface.
Step 4 (Optional) Run:
peer peer-address description text
The description of the MSDP peer is added.
The configuration helps to distinguish the remote MSDP peers and manage the connections with
the remote MSDP peers.
The parameters of the command are explained as follows:
l peer-address: specifies the address of a remote MSDP peer.
