Mastering BGP
Mastering BGP delves into its architectural strengths: reliability (TCP foundation, keepalives), stability (MAI, dampening, route refresh), scalability (reflection, confederations, selective propagation), and flexibility (policy-driven, path attributes, communities).

The Internet, in its magnificent global sprawl, is fundamentally a network of networks. Unlike the neatly contained domains governed by Interior Gateway Protocols (IGPs) such as OSPF or EIGRP, the vast inter-domain landscape requires a routing protocol designed for entirely different challenges. Enter the Border Gateway Protocol (BGP)—the undisputed

At its core, BGP is about establishing and maintaining peering relationships between routers. Before any routing information is exchanged, both routers must progress through a defined sequence of connection states, managed by the BGP state machine.
