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.

IS-IS TLVs define how routing information is shared and covering IPv4, IPv6, traffic engineering, and more. This extensible model makes IS-IS a preferred protocol for modern networks. Dive deeper with our Mastering IS-IS series.

Go is fast, portable, and built for concurrency that makes it perfect for large-scale, production-ready network automation. In this post, we explore why Go is a strong alternative to Python, its advantages for API-driven workflows, and how it can simplify building reliable automation tools.

BGP route types are the language of VXLAN EVPN. They carry MAC, IP, and reachability info between VTEPs. Understanding them is key for building and troubleshooting EVPN fabrics, whether for multi-homing, L2, L3, or BUM traffic.

Optimize your network for speed and stability with this deep dive into IS-IS convergence. We explore fast timers, BFD, and SPF throttling to achieve sub-second convergence. Learn how Graceful Restart and the Overload Bit ensure resiliency during critical events.

In this part, we explore the Link-State Database (LSDB) and how LSPs are exchanged to build a synchronized network map. We'll also dissect the SPF algorithm, and demystify crucial concepts like timers, Administrative Distance, route filtering, and summarization to maintain a scalable network.
