[c-nsp] STP and PVST..

[Ambedkar]

Namaskaram,
I am having a problem of inter-operability of Cisco switches and Non-Cisco
switches.

The configuration as follows

Cisco Switches:
PVST and RPVST (Proprietary protocols)

Non-Cisco Switches:
STP and RSTP (Open Standard)

In STP/RSTP, both the Cisco and Non-Cisco switches are becoming Root
bridges, and when failover has to take place, the time to converge is more.
I guess BPDU packets are not exchanged properly.

Any help how to resolve this issue..

Thanks
