Does anyone have an example configuration for rstp between HP and Brocade switches? I have been working with (2) HP 5820 configured as an IRF and (2) SX-800. The SX-800's are the root and secondary bridges each with a connection to the HP's IRF configuration. Each attempt we have tried has failed after a short time or when pinging the servers connected to the HP's we get an occassional ping drop. Any help would be greatly appreciated. Thank you.
