Hi Rodolfo,

At the moment it seems that it has fixed the issue. Basically we added
that in the past not thinking about external ports.

I marked it as invalid in Neutron, if we'll see any issues - we'll reopen in future.
Thanks for your help!

Bug description:
  OpenStack release affected - Wallaby, Xena and Yoga for sure
  OVN version: 21.12 (from CentOS NFV SIG repos)
  Host OS: CentOS Stream 8

  Neutron creates External ports for bare metal instances and uses ha_chassis_group.
  Neutron normally defines a different priority for Routers LRP gateway chassis and ha_chassis_group.

  I have a router with two VLANs attached - external (used for internet
  connectivity - SNAT or DNAT/Floating IP) and internal VLAN network
  hosting bare metal servers (and some Geneve networks for VMs).

  If an External port’s HA chassis group active chassis is different
  than gateway chassis (external vlan network) active chassis - those
  bare metal servers have intermittent network connectivity for any
  traffic going through that router.

  In a thread on ovs-discuss ML - Numan Siddique wrote that "it is recommended that the
  same controller which is actively handling the gateway traffic also
  handles the external ports"
