How to enable loose RPF on OSP controllers via tripleo/heat

Solution Unverified - Updated -

Issue

  • Due to firewalls, I am using policy based routing to ensure that traffic coming into the external API VIP is returned back out the same interface.
  • Due to RHEL8 using RFP strict mode, the packets received are dropped and a martian packet is logged by the kernel.

Environment

  • Red Hat OpenStack Platform 16.1
