CCNP-BCMSN and PVST

Unanswered Question
Aug 26th, 2008

Hello people...

I'm preparing to take the BCMSN (642-812) exam and the following question just arise...

Since PVST is a cisco proprietary protocol and you need to use ISL trunking encap between switches....

What happens when your access switches are 2950s or 2960s that DO NOT support ISL trunking ? would you need to implement PVST+ instead ?

makes sense ?

I have this problem too.

when you turn on PVST, you automatically run PVST+, which runs over 802.1q trunks. The same with Rapid-PVST.

Thanks
