Table 6-2  MSDP configuration tasks



Configuring Basic MSDP Functions

When a PIM-SM network is divided into multiple PIM-SM domains, configure basic MSDP functions on multicast switches to allow the RP in each domain to learn multicast source information in other domains and allow group members in one domain to receive multicast data from multicast sources in other domains.

Configuring SA Message Control and Caching

MSDP peers share (S, G) information by exchanging SA messages. To control SA message transmission, configure SA message control and caching.

Configuring MSDP Anycast RP

Anycast RP allows multicast sources to register with the closest RP and allows receivers to join the closest RP. This mitigates loads of a single RP, implements RP redundancy, and optimizes forwarding paths.

The MSDP multi-instance configuration is included in all configuration tasks.

MSDP peer relationships can be set up between interfaces of multicast devices in the same instance (public instance or VPN instance). MSDP peers exchange SA messages to implement inter-domain VPN multicast transmission.
