Interaction with Interior Gateway Protocols during Convergence
One perplexing problem with large-scale BGP deployments, particularly when BGP speakers are connected over multiple-hop networks within the autonomous system, is how to handle convergence time differentials between the interior gateway protocols. Figure 7.11 illustrates.
Figure 7.11. BGP Interaction with interior gateway protocols during convergence.
To understand how a differential in the convergence time between an interior gateway protocol and BGP can cause traffic to be dropped, let's work through a network event and the convergence that occurs afterward. Let's begin with router ...
