Multiple OSPF instances on one interface

In bird you can create multiple OSPF instances per interface using parameter “instance id” (see The BIRD Internet Routing Daemon Project)

How can I distinguish the instances on VyOS side? I am not able to find “instance id” in the docs.

My goal is to have one instance for supplying the default route and one instance for the remaining routes (so I can put them into separate routing tables).

Edit: Seems this is an extension, RFC 6549. Is this not supported by VyOS? If not, do I have any other option running multiple OPSF instances on one interface?
