@cmr Its a transit VLAN on the connections between the two core switches that we use to route traffic between the two networks. Both sides have a set of MX firewalls on top that we use for internet and auto-vpn failover in case the link between the two switches goes down. Geographically the sites are a couple miles apart. ...

Proper STP port configuration for Core switches on two separate networks

I have two networks that have a pair of stacked MS425-32 switches as the root bridges on each side. These networks are setup as two separate networks on the Meraki dashboard and they are each configured to be the root bridge in Switch Settings for their network. These two pairs of core switches connect to each other with two fiber connections. I want to make sure that these two sets of switches remain the root bridge for their sides of the network. Currently I have RSTP disabled on the aggregate ports on the MS425 stacks. STP Guard is set to Disabled. I don't think this is the right setup. I don't want spanning tree updates on one network to effect the other network, possibly causing an issue with which set of MS425's is the root bridge - each set should be the root bridge for its side of the network. How should STP be configured on the ports that connect these two networks together on the MS425 stacks?   ... View more
