[j-nsp] STP Between Cisco and Juniper

[Saba Sumsam]

Hi,
I have a Layer 2 network consisting of a Cisco 2970G, SRX210 and SRX100.
Following are the STP modes supported on each:

Cisco 2970G: mst, pvst, rapid-pvst
Juniper SRX100: STP, RSTP. MSTP
Juniper SRX210: STP, RSTP

My question is: Is Cisco mst interoperable with Juniper RSTP. What mode
should I be using on each device in this case?

Suggestions highly appreciated.

Regards.
