Split Horizon and Poison Reverse are TWO DIFFERENT THINGS. They do not work
together, they are *alternatives*, similar to how ISL and 802.1Q are
alternatives which do pretty

Newbie question
Is the max hop count for rip 15 and the poison reverse infinity count 16?
Thanks

The max hop count is 15, as you know. If a router advertises a route as
being 16 hops, it's saying that the distance to the network is "infinity,"
in other words
So for poison reverse, does it mean that it's
temporarily breaking the rules of "split horizon" bye
sending the route advertisement back (on the interface
that it received it from) to the original router who
sent it?
If that's the case. What would cause this process to
occur? I'm looking for a
same reason why split horizon does what it does:
loop avoidance.

The "poison reverse" term is sometimes used to mean sending a poisoned
route outwards. In that case it doesn't break the rules of split horizon
and it's just a way of explicitly saying this route is no longer reachable,
rather than simply omitting the route from the list. Sometimes it is sent
