What I am missing with Licensed Gear and Switches is the option of a second gateway in case the first fails.
We've most of our towers connected from 2 sides and OSPF handling the routing. But when a link fails I cant
reach the other side of the link and the switch there as they use the dead gateway instead of switching default
gateway to the other working link.

So my monitoring shows some dead devices which are not dead but cant find the way.

A simple ping check and switching the gatway to a secondary when 60s of pings fail would help a lot with
troubleshooting outages.

This is not a feature I think we would implement because if you set your network up properly with OSPF this is not an issue.

I am unaware of any NON router device that allows multiple gateways. It would be possible to do but you really do not need it.

We run OSPF between towers in a ring and we can lose a backhaul to a tower and never lose access to anything.

We run the POE for the backhauls through the switch configuring the switch to act as a mid-span so that the radios go directly to the router port.

The 2 routers ports on each end of the backhaul have an IP within the same subnet on their interface for OSPF and the Radio at each end has a /30 subnet as a secondary IP on each router as the default gateway to each radio.

We then have a STATIC LAG defined between the router and the switch for all the radios on that tower NOT INCLUDING THE BACK HAULS. We do the LAG to share the pause frames that will be generated by the AP interfaces across multiple interfaces to the router so there are fewer pause frames affecting the local tower radios. And since the backhauls do not participate in this LAG but rather are on different interfaces they are not effected by the local AP generated pause frames so traffic passing through the tower to the next is not affected.

We also have an invalid subnet at each tower for local tower equipment such as switches, mFi, and such.

Since each switch port is a separate VLAN to the router basically making them logical routed ports each AP is in it's own invalid /30 subnet.

You can get the just of what we are doing in my thread where I show you how I set up a tower: viewtopic.php?f=30&t=452
