Thanks for the extra information.

I still think that that interface did not come back up properly on the firewall side, and so it was not processing traffic. That would explain the missing static route. Given that you had a missing static route too, I don't think that you should be worried about your confidence in OSPF on SPLAT - the issue is at a lower level than that.

I suspect it didn't deal properly with the negotiation change, but on reboot it did sort itself out, which is why you could access it again.

Did you do any troubleshooting on that interface before rebooting it?
