Border Gateway Protocol (BGP) is not merely a protocol—it’s the backbone of the internet. For service provider engineers and network architects, BGP is an indispensable tool that enables global connectivity, supports MPLS VPNs, and underpins many critical network...
Before we look at BGP path hunting, let’s first discuss the RIP count to infinity problem. RIP, the Routing Information Protocol, is pretty much the simplest bgp table imaginable. RIP simply broadcasts the contents of the local routing table over UDP every 30...
There are several route optimization techniques applied to networks distinguished by a single routing domain. The traditional approach requires network engineers to apply various routing policies and re-route the traffic manually. Fortunately, the traditional approach...
