Description Tim Rozet 2020-10-21 19:22:58 UTC

+++ This bug was initially created as a clone of Bug #1890270 +++

Description of problem:
With external IP the address may not live on any node. In this case when the packet arrives at any master/worker node (with the destination address of the external IP) it should be routed into OVN. This is currently broken and the route that gets injected into the host is incorrect.
