There was a problem hiding this comment.
Have to go through the OSPF template again, but it looks OK and if there are minor details, I can fix them before merging.
However, if you have to add a static route to generate the default, it would be really nice to make it a floating static route (low preference/high admin distance/whatever it's called), so that if we get a different default route from somewhere else, we prefer that one.
Also, you need the (floating) static default route only when ospf.default.always is True (https://netlab.tools/module/ospf/#specifying-external-default-route)
Export default routes via OSPF filters with E1/E2 metrics, use static routes for always-originate, and restrict conditional origination to BGP and static sources to avoid re-advertising OSPF-learned defaults. Co-authored-by: Cursor <cursoragent@cursor.com>
