Hi,I notice with many of Cisco's labs, that fast ethernet switches are used with gigabit routers. In reality, is this best practice? Would the lesser fast ethernet switches in these cases slow the traffic??? If not please explain why. If so, why woul...

Hi,My question is: Why is point-to-point topology configured in loopback? Is it because of the fact that loopback never goes down unless it is manually shut down or if the router crashes, or, is there/are there another explanation(s). Thanks,joe.
