MSDP function configuration (1)

MSDPA mechanism for connecting multiple PIM-SM domains is described. Each PIM-SM domain uses its own independent RP, which is not dependent on the RP in other domains and is configured with the RP of the MSDP peer to route the active Multicast Source Information in its domain through the SA activity source) the message advertises all MSDP peers to it, so that multicast source information in one PIM-SM domain is passed to another PIM-SM domain.

Through the above description of MSDP, let's take a look at how MSDP is implemented.

Requirement Analysis

1. PIM-SM network uses a single BSR management domain, with Multiple Multicast Source S and multiple receivers. When a new member joins a multicast group, the switch directly connected to the receiver can initiate a join to the RP closest to the topology by configuring Anycast RP in the PIM-SM domain;

2. OSPF is run in the PIM-SM network to provide unicast routing, and MSDP peer is established between SwitchC and SwitchD. At the same time, SwitchC and SwitchD Loopback10, Loopback0 interface to assume the role of C-BSR and C-RP;

3. This case applies to H3C 3600-EI, 5600, 3610, and 5510 series switches.

The networking diagram is as follows:
