Configure the Multicast Source Discovery Protocol
Configuring MSDP is a four-step process.
1. Enable an exterior gateway protocol (EGP) with at least two routing domains.
Refer to the following figures.
The MSDP Sample Configurations show the OSPF-BGP configuration used in this chapter for MSDP.
Also, refer to Open Shortest Path First (OSPFv2 and OSPFv3) and Border Gateway Protocol IPv4
(BGPv4).
2. Configure PIM-SM within each EGP routing domain.
Refer to the following figures.
The MSDP Sample Configurations show the PIM-SM configuration in this chapter for MSDP. Also,
refer to PIM Sparse-Mode (PIM-SM).
3. Enabling MSDP.
4. Peer the RPs in each routing domain with each other. Refer to Enabling MSDP.
