we have copied all the route fromthe cisco L3 to the meraki L3  no dynamic routing protocols  All the DHCP server and applications servers are on  others subnets.  we also have added the route to these network  the default route is going through the mx firewall  DHCP servers and ERP applications traffic is going through the VeloCloud appliance      I have just noticed I have RSTP enable. Does it could be the culprit?         I don't have it enable on another similar configuration
