description |
In a focal-ussuri deployment when enabling `enable-distributed-floating-ip` traffic from instances with FIPs should exit the HV directly and not go through a gateway chassis.
However due to a bug each HV will attempt to do ARP processing locally even for IP addresses not in the external network CIDR.
This results in loss of connectivity for instances with FIPs.
The issue is not present in Groovy with OVN 20.06 and I suspect the issue is fixed by this commit:

[Impact]
Enabling `enable-distributed-floating-ip` on a cloud with OVN 20.03 results in loss of external connectivity for instances with floating IPs.
[Test Case]
Launch two instances and assign floating IPs to them. Toggle the `enable-distributed-floating-ip` configuration option and attempt to access a IP address on the internet that is not reachable in the external network L2 broadcast domain.
Observe as the instances will attempt to reach the IP by obtaining it's MAC address through ARP resolution directly rather than applying L3 routing.
The functional test gate of the neutron-api-plugin-ovn charm may be useful for verification.
[Regression Potential]
We have cherry-picked a patch from upstream that reverts the change that introduced the erratic behavior in its entirety. The optimization has later been replaced by a new set of patches which is available in newer versions. As such the regression potential is minimal.
