Spanning tree design issue

Hi all,

Is it possible to combine the new 802.1w/s with the Cisco prop. PVST+ and MISTP. For example we've got 6500 in the distribution layer which does support 802.1w/s and 3500 in the access layer which does not support 802.1w/s. Is it possible to build one instance in the distribution layer using 802.1s and run PVST+ or MISTP in the access layer.

Thanks in advance..

You can have a mix of PVST and MST(802.1s)/RSTP(802.1w)
