Configuring Inter-AS MSDP Peers for BGP Peers

To enable PIM-SM domains in different ASs to share multicast source information, configure an MSDP peer relationship between Rendezvous Points (RPs) in different ASs in which a BGP peer relationship is set up.

Context

Establish a BGP peer relationship between the RPs in different ASs and then perform the following steps:

Procedure

Run system-view
The system view is displayed.
Run msdp [ vpn-instance vpn-instance-name ]
The MSDP view is displayed.
Run peer peer-address connect-interface interface-type interface-number
An MSDP peer connection is set up.
- peer-address: specifies the IP address of a remote MSDP peer. The address is the same as that of the remote BGP peer.
- interface-type interface-number: specifies the local interface connected with the remote MSDP peer. This interface is the local BGP peer interface.
(Optional) Run peer peer-address description text
A description is added for the remote MSDP peer.

This configuration helps you differentiate remote MSDP peers and manage the connections with the remote MSDP peers.
- peer-address: specifies the IP address of a remote MSDP peer.
- text: specifies the description text. The text is a string of a maximum of 80 characters.
Run commit
The configuration is committed.
