Description Tim Rozet 2020-12-17 19:43:37 UTC
Description of problem:
We currently do not check the ip family type between the gateway and the pods in the affected namespace. We need to add routes according to ip types. Additionally we need to ensure that if a pod in a multi-gw namespace only has routes for a single ip family type, we need to reject traffic from the other type. This will stop traffic from leaking to the cluster's default gw.
