For a limited time we are publishing the Route Redistribution videos from our CCIE Routing & Switching Advanced Technologies Class for public viewing. These videos cover all aspects of Route Redistribution needed for the CCIE R&S Lab Exam outside of the scope of MPLS, and will also be useful for any engineers looking for more information on how the Route Redistribution process works.
Introduction In this series of posts, we are going to review some interesting topics illustrating unexpected behavior of the BGP routing protocol. It may seem that BGP is a robust and stable protocol, however the way it was designed inherently presents some anomalies in optimal route selection. The main reason for this is the fact that BGP is a path-vector protocol, much like a distance-vector protocol with optimal route selection based on policies, rather than simple additive metrics. The fact...
