Can you give me an example of what you mean by this?

I have been more focused on the initial VRF infrastructure and have not
spent too much time on these use cases or other route lookup features
(e.g., allow an application to handle route lookup misses similar to arp
misses, allow custom route lookup modules) that are needed to approach
the feature richness provided by high end routers.
