Currently have Cisco edge switches and have to replace core switching with Meraki. Meraki switch will need to be STP root but the Cisco equipment is configured with rapid-pvst. Meraki cannot be root in this scenario, it doesn't seem to support per vlan spanning tree. The Cisco side doesn't seem to support just standard RSTP. The only option I see is to use MSTP on Cisco and put all vlans in instance 0. If I use anything other than instance 0 the Meraki won't become root. Is this the only way to do this?
