I have some doubts regarding the interaction of a switch running MSTP (802.1 S) with other switches running legacy 802.1D and 802.1W.
Lets say S1 running MSTP is connected to S2 and S3 via ports 1 and 2 with S2 running 802.1W and S3 running 802.1D.
Now when port 1 on S1 receives a RSTP BPDU, i believe the MST will start a "PVST+" simuation and send out a RsTP BPDU out that port. Correct?
Now when port 2 on S1 receives 802.1D BPDU, will it send the legacy 802.1D BPDU out that port to S3, and activate the timers like MAXAGE and FWDDELAY with the default values?
Basically, what i want to know is how MSTP interacts wilth all other bridging protocols. It would be great if someone could point to any Cisco white papaer/documentation on this.
Thanks in advace!!!
