OSPFv3 is configured to filter the imported routes.
Using the
filter-policy
command, you can only filter the routes calculated by OSPFv3. Routes
that do not pass the filtering are neither added to the OSPFv3 routing table nor advertised.

6.7.4 Configuring OSPFv3 to Import External Routes
Importing the routes discovered by other routing protocols can enrich OSPFv3 routing
information.
Context
Because OSPFv3 is a link state-based routing protocol and cannot directly filter the advertised
LSAs, OSPFv3 must filter the routes when importing them. Then, only the routes that pass the
filtering can be advertised.
Procedure
