Recently completed a major upgrade to my school's network and we are now 100% full stack Meraki. Prior to the upgrade, all switches were home run to our MX250. I realized a couple years later that was a mistake since the MX doesn't handle STP, LLDP/CDP properly. But that's now fixed, as I've aggregated all IDF uplinks to a new MS425-16, which is also my L3 router now. I have a single transit VLAN between the MS425 and the MX250 and both switch ports are set to access ports on that VLAN. Static routes are entered and everything seems to be running smoothly.
However, the topology view is not quite accurate. Why does the link layer view say there is not enough info to draw the root? I've got STP bridge priority set to the new core (MS425) at 4096. Clearly it's set to the root.
