Nice. Thanks. But I'm pretty sure this was not an option 2.5 years ago when I asked the question. LOL

but does the route withdraw itself or do you have to physically remove it? Neither of these are what I would call solutions for floating static routes.

We tried to change to MST but this did not work. We kept the bpdufilter on. You are correct, I think the port only blocked when we had pruning on one side and not on the other.

Though I did not try to configure MST on the Cisco Catalyst side, I did ensure that the trunk settings on both sides were identical (as the fist document states). I knew to do this because on the homogeneous network that we did, I had a trunk that would not come up at all, (or behaved badly, I can't remember which) because we had it pruned on one side and not on the other. I will try MST on the Cisco side and see if that works. Filtering bpdus makes me nervous...I'd rather make it work.

This is more of a warning than a question. I have just completed two large Meraki MS deployments. In one we had to integrate Merakis on a legacy Cisco Catalyst infrastructure where only some Catalyst switches were being replaced. Many were remaining. Issues: Our native VLAN was configured for VLAN ID 5 on both sides of the trunk. MS350 on one side, Catalyst 3750 and 3850s on the other. Cisco Catalyst switch reported a VLAN ID mismatch for 3 of 8 allowed VLANs This caused the trunk to be blocked for those VLANs on that single trunk (meaning only one trunk from that switch existed to the network and it was blocking for those vlans) The only fix was turning on "spanning-tree bpdufilter enable" or turning spanning-tree off. I am surprised that I have not seen more people complaining about this. In the other deployment where I had a mostly homogeneous Meraki network, I still had to disable spanning tree on the port to our ISP uplink and make sure our MDF stack was root or we saw all kinds of wonky behavior. So my warning is, if you are seeing issues that dont make sense, check Spanning-tree...
