What does a metric of 16 hops represent in a RIP routing network?
16ms
 Number of routers in the internetwork
 Number of hops
 16 hops - unreachable
 Last hop available
What are holddowns used for?
To hold down the protocol from going to the next hop.
 To prevent regular update messages from reinstating a route that has gone down.
 To prevent regular update messages from reinstating a route that has just come up.
 To prevent irregular update messages from reinstating a route that has gone down.
What is split horizon?

When a router differentiates on which interface a packet arrived and does not advertise that information
back out the same interface.
 When you have a large bus (horizon) physical network, it splits the traffic.
 It holds the regular updates from broadcasting to a downed link.
 It prevents regular update messages from reinstating a route that has gone down.

What is poison reverse?
It sends back the protocol received from a router as a poison pill, which stops the regular updates.
 It is information received from a router that can't be sent back to the originating router.
 It prevents regular update messages from reinstating a route that has just come up.
 It describes when a router sets the metric for a downed link to infinity.
