MSDP Compliance with IETF RFC 3618
The MSDP Compliance with IETF RFC 3618 feature enables you to configure Multicast Source Discovery Protocol (MSDP) to comply with the peer-RPF forwarding rules defined in the Internet Engineering Task Force (IETF) RFC 3618 specifications. Enabling the MSDP Compliance with IETF RFC 3618 feature prevents Source-Active (SA) message loops. Additionally, enabling the MSDP Compliance with IETF RFC 3618 feature eliminates the requirement that Border Gateway Protocol (BGP) route reflectors (RRs) run MSDP, enables the use of an Interior Gateway Protocol (IGP) for the Reverse Path Forwarding (RPF) check, and allows MSDP peerings between routers in nondirectly connected autonomous systems.
Configuration information is included in the "Using MSDP to Interconnect Multiple PIM-SM Domains" module at the following URL:
