After reviewing the man page on babeld, and draft-ietf-rtgwg-policy-model, I have to agree with Juliusz that draft-ietf-rtgwg-policy-model does more than what is expressed in the babeld man page. There are a few things like router-id that the routing policy module does not model, which Juliusz says is not necessary.

Therefore I am inclined not to try to define a module to extend the routing policy for babeld. If anyone disagrees, please speak up now.

Thanks.
