Configuring Multicast Source Discovery Protocol

Configuring MSDP is a three-step process:

1. Enable an exterior gateway protocol (EGP) with at least two routing domains.

Figure 29-5 and MSDP Sample Configurations on page 654 show the OSPF-BGP configuration used

in this chapter for MSDP. Otherwise, see Chapter 33, Open Shortest Path First (OSPFv2 and

OSPFv3), on page 707 and Chapter 10, Border Gateway Protocol IPv4 (BGPv4), on page 207.

2. Configure PIM-SM within each EGP routing domain.

Figure 29-5 and MSDP Sample Configurations on page 654 show the PIM-SM configuration in this

chapter for MSDP. Otherwise, see Chapter 35, PIM Sparse-Mode, on page 771.

3. Enable MSDP. See page 638.

4. Peer the RPs in each routing domain with each other. See page 638.
