Implementation Information
The Dell EMC Networking OS implementation of MSDP is in accordance with RFC 3618 and Anycast RP is in accordance with
RFC 3446.
Configure 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 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. Enable MSDP.
4. Peer the RPs in each routing domain with each other. Refer to Enable MSDP.
