Distributed Virtual Routing functionality in Red Hat Enterprise Linux 7.5

Solution In Progress - Updated -

Issue

  • After updateing to kernel 3.10.0-862.3.2.el7.x86_64 DVR functionality cease to function because conntrack/netfilter doesn't track packages in specific network namespace if those packages were processed by conntrack --notrack target in other network namespace.
  • DVR is implemented with two namespaces on compute host: qrouter-UUID and fip-UUID.
