Description
We want to support path selection policies similar to PAN.
This could include the following features:
- policies (stateless, determine which paths are filtered out and their order) => 1. priority Simple Path Selection Policies #31
- path policy language (special policy that is formulated with a special file format) => 2. priority, focus on ACLs first and then sequences if necessary Path Policy Language #44
- selectors (stateful, determine which path is used for each packet) => 3. priority (maybe)
