MSTP & PVST+ interoperation

Hi,

I have a region of MSTP that must communicate with a zone of PVST. Because of historical reason, I must leave the Root bridge in the PVST+ zone, but in theory, the MSTP region want to have the Root Bridge inside, that's why interfaces of routers in this region are in the unfunctional state when doing a "show spanning-tree":

Root BKN* 20000 128.1 P2p Bound(PVST) *PVST

Do you have any ideas how to resolve this problem considering that I can just change the configuration in the MSTP zone but not to PVST zones?

Is there any things of Cisco like Topology-group with the Master Vlan of Brocade, where we can take a Vlan in mode PVST and mapping all others Vlans to this Vlan (only one instance of PVST)?

Thanks for your help,

Viet
