RKE: how to disable rp_filter?

I have deployed k8s cluster with RKE, but after k8s deployed, rp_filters for all network interface set to 1 even in /etc/sysctl.conf was set to 0. this caused problem for openstack-helm.

how do I disable rp_filter using Rancher RKE?

thanks.

@cliu. rp_filter inside the container? Or is it being modified on the VMs themselves.

rp_filter on the K8s hosted machine after deployment… master nodes/worker nodes.
