That’s by design.. typical answer is to use VLAN’s (subinterfaces) to talk OSPF to other networks – and in most wireless networks you could set that up …. Just sayin ;)

One reason is it’s really hard to do otherwise on Cisco, I’m not aware of a way to get Cisco to talk OSPF on a secondary IP (there probably is and I just don’t know how). If I have a micropop or customer router situation where I’m passing a block to a router via an AP, I will make it a static route and redistribute the static route with an ACL, rather than run OSPF over a multipoint network that connects to CPE. And if I genuinely had a multipoint backhaul link, I would probably use a /29 or /28 rather than a bunch of /30’s. Note I say this not because I’m an OSPF expert, but the opposite, so I don’t want to get fancy.

I was told unless you know what youre looking at that OSPF logging is confusing. Is this normal to be seeing? That looks like you are sending packets that: 1. Shouldn't be sent (speaking OSPF from IPs you shouldn't) OR 2. You have a bridge loop or similar that is allowing packets from other interfaces to come back to this router You can send this offlist if you want, but do: /routing ospf export Post that information and it will be easier to see what's happening.
