I don't think you need to extend anything.  Matching on router-id is not
essential.

On the other hand, it looks to me like it's more expressive than anything
that any implementation of Babel known to me has ever implemented.  Since
I'm still not sure what's the purpose of the YANG model, I don't know if
that's a problem or not.

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.
