This section presents the following topics:

• Configuring the PIM domain
• Configuring BGP
• Configuring MSDP peers
• Configuring an MSDP peer group
• Configuring MSDP filters
• Verifying the status of MSDP-PIM
• MSDP configuration example

Sample MSDP topology is a sample of the MSDP topology in three domains, or IPv4 autonomous systems (AS), each with an RP in a different AS configuration. This example shows how to deliver the multicast data to receivers from another multicast domain, for example, for AS2 receivers from AS1 or AS3 senders.

All routers in this scheme are MSDP peers except R1, which is a border router with the R6 MSDP peer situated behind it in the AS1 autonomous system.

To view the steps to achieve this configuration, refer to MSDP configuration example.
