If you redistribute something into a protocol, say rip, that doesn't mean
that you have started the rip process on the redist. interface, it just
means your putting that prefix into the rip process. If you do a "show ip
protocols" you will see what interfaces are active in whatever routing
protocol your running. The question then is what defines ACTIVE? If rather
then redistribute, say you ran ospf and put a network statement into the
ospf domian but then made the interface a passive interface. Does a passive
interface mean you have two active protocols? I would say no, because you
have only active protocol and the other is passive.
