I have a network that is already at about 9 switch-hops end-to-end. We can't get around doing this, but knowing that STP recommends switch-hop limits to be 7, I've read that RSTP and RPVST(+) don't have this limitation. Is this true? I need to add a couple more switches. It may not be optimal, but functional is more important right this second. Bottom-line - does R-PVST have a switch hop limit like STP's 7? We, obviously use R-PVST.
