The problem with this approach is you now have non-deterministic routing.

Depending on the state of FIB compression, packets *may* flow out interfaces that are not what the RIB thinks they will be. This can be a good recipe for routing micro-loops that come and go as your FIB compression size ebbs and flows.

Had NOT considered the looping - that's what you get for writing in public without thinking it all the way through *blush*.

Thanks for poking holes appropriately,
Tim.
