Multicast

Anycast RP with MSDP brings true redundancy and load sharing to multicast networks. By synchronizing active sources across multiple RPs, it ensures seamless failover and scalability—making multicast delivery resilient for IPTV, trading, and real-time applications.

Multicast‑routing with PIM (Sparse, Dense, SSM, Bidirectional) lets network architects deliver ultra‑low‑latency streams and market‑data feeds. Choose the right mode like SPT via SSM for HFT, shared trees with RP for global video to balance latency, scalability, and security.

IP multicast is the unsung hero of efficient one-to-many communication. Instead of flooding or duplicating streams, multicast delivers content only where it’s needed. This deep dive covers addressing, IGMP, PIM routing, configs, and troubleshooting to make multicast click in real networks.
