NO.6 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 send updates to
their adjacent routers. Once the process is complete for all routers, the networks have converged.
B. Convergence is triggered when the physical interfaces between routers R1 and R2 go down. At this
point, both routers R1 and R2 re-compute their link state database and send updates to their adjacent
routers. Once the process is complete for all routers, the networks have converged.
C. Convergence will not be triggered because switches cannot run routing protocols between them.
D. Convergence is triggered when the switches notify the routers about the link state information. At this
point, both routers R1 and R2 re-compute their link state database and send updates to their adjacent
routers. Once the process is complete for all routers, the networks have converged
E. Convergence is triggered when an LSA is sent from router R1 to router R2 to indicate that the link is
down. At this point, both routers R1 and R2 re-compute their link statedatabase and send updates to their
adjacent routers. Once the process is complete for all routers, the networks have converged.
