Just so, can STP and RSTP be mixed?
It is possible to mix PVST and MST (RSTP requires MST), but it needs some planning, and it can be fragile, as you have discovered. You would probably be better off using the same STP version across all your switches. You could change the STP on the Cisco switches to match the rest of the switches.
Subsequently, question is, how is RSTP faster than STP? RSTP converges faster because it uses a handshake mechanism based on point-to-point links instead of the timer-based process used by STP. For networks with virtual LANs (VLANs), you can use VLAN Spanning Tree Protocol (VSTP), which takes the paths of each VLAN into account when calculating routes.
Keeping this in view, what is the difference between RSTP and STP?
one difference is that Rapid Spanning Tree Protocol (RSTP IEEE 802.1W) assumes the three Spanning Tree Protocol (STP) ports states Listening, Blocking, and Disabled are same (these states do not forward Ethernet frames and they do not learn MAC addresses).
What are the RSTP port states?
RSTP defines three port states: discarding, learning, and forwarding and five port roles: root, designated, alternate, backup, and disabled. A RSTP capable switch determines what spanning tree will be computed by the algorithm, but the rules as written require knowledge of the entire network.
