19.7.0
^^^^^^


Known Issues
************

* The *redirect-type=bridged* option is only used if all the tenant
  networks connected to the router are of type VLAN or FLAT. In this
  case their traffic will be distributed. However, if there is a mix
  of VLAN/FLAT and geneve networks connected to the same router, the
  redirect-type option is not set, and therefore the traffic for the
  VLAN/FLAT networks will also be centralized but not tunneled.


Bug Fixes
*********

* 1986003 (https://bugs.launchpad.net/neutron/+bug/1986003) Fixed an
  issue with concurrent requests to activate the same port binding
  where one of the requests returned a 500 Internal Server Error. With
  the fix one request will return successfully and the other will
  return a 409 Conflict (Binding already active). This fixes errors in
  nova live-migrations where those concurrent requests might be sent.
  Nova handles the 409/Conflict response gracefully.

* [bug 2003455 (https://bugs.launchpad.net/neutron/+bug/2003455)] As
  part of a previous commit
  (https://review.opendev.org/c/openstack/neutron/+/875644) the
  *redirect-type=bridged* option was set in all the router gateway
  ports (cr-lrp ovn ports). However this was breaking the N/S traffic
  for geneve tenant networks connected to the provider networks
  through those routers with the redirect-type option enabled. To fix
  this we ensure that the redirect-type option is only set if all the
  networks connected to the router are of VLAN or FLAT type, otherwise
  we fall back to the default option. This also means that if there is
  a mix of VLAN and geneve tenant networks connected to the same
  router, the VLAN traffic will be centralized (but not tunneled). If
  the traffic for the VLAN/FLAT needs to be distributed, then it
  should use a different router.
