[j-nsp] JunOS RPKI/ROA database in non-default routing instance, but require an eBGP import policy in inet.0 (default:default LI:RI) to reference it.

[David Sinn]

I'd try the 'notification-rib' chunk in the 'validation' stanza of the routing-instance and see if setting inet.0 there pushes the DB the way you need. Certain versions of JunOS are quite broken going the other way, so I've had to enumerate all of the routing-instances that I want to be sure have a copy of the validation DB to get them to work correctly. Maybe the other way will work in your case.

You can also have it query against that instance on an import policy for that VRF specifically, and if there's no session, it will revert to the default RPKI RV database (if configured) under the main routing-options {} stanza to check for valid/invalid, etc...

Hence when I try to do ROA validation of an eBGP peer in inet.0 via a standard import policy, the RV "validation-database" is unfortunately locked inside the admin-vrf, and thus isn't queried for valid/invalid/unknown etc.
