Are there any special compatibility considerations to allow MSTP to interoperate with legacy STP or RSTP?
IEEE 802.1s MSTP includes RSTP functionality and is designed to be compatible with both IEEE 802.1D and 802.1w spanning-tree protocols. Even if all the other devices in your network are using STP, you can enable MSTP on the 2510 switch. Also, using the default configuration values, your switches will interoperate effectively with STP and RSTP devices. MSTP automatically detects when the switch ports are connected to non-MSTP devices in the spanning tree and communicates with those devices using 802.1D or 802.1w STP BPDU packets, as appropriate.
