What triggers convergence of the routing protocol when the link between switch 1 and switch 2 goes down?
Click the exhibit button. What triggers convergence of the routing protocol when the link between switch 1 and switch 2 goes down? A. Convergence is triggered when the adjacency between routers R1 and R2 drops as a result of Hello timeouts. At this point, both routers R1 and R2 re-compute their link state database and […]
