How would local gateways connect ? A Tunnel(s) to the global gateways ?

I'm trying to imagine explaining to someone how to configure an IGP (especially IS-IS) :-)

yes, IPIP tunnels or GRE to their local gateway. If they wanted to have redundancy into the AMPR net they could do IS-IS L1 to the two gateways over these tunnels. The backbone routers would all be L2 routers.

We could do OSPF, but I see the whole area 0 thing being a bad architectural limitation. Any design we come up with should be redundant and scalable for all hams to benefit from.

Really if you can't configure a link state routing protocol, should you even be trying to setup a redundant connection?

Granted it would be optional, but it would give some real protection if one of the border routers goes down.

We only have a /8 of space, and even subdivided into /24's it's only 65k routes, so pretty much any router on the core can handle it.
