Mutual Redistribution at Multiple Routers

When multiple routers redistribute between the same two routing protocol domains, several potential problems can occur. One type of problem occurs on the redistributing routers, because those routers will learn a route to most subnets via both routing protocols. That router uses the AD to determine the best route when comparing the best routes from each of the two routing protocols this typically results in some routes using suboptimal paths. For example, Figure 10-4 shows a sample network,...
