[OVSDB-125] Remaining OF 1.3 rules after full neutron resources removal

Thu, 19 Oct 2017 21:28:22 +0000

(Using Helium release and VxLAN overlays), some OpenFlows rules remain after deleting all the neutron resources. It fails (at least) for ports which device_owner is equal to network:dhcp.

This bug was introduced by Helium release.

To reproduce it (ODL MD in master):

create a private network and a subnet (DHCP activated)
launch a VM
delete the VM, next the subnet, next the network.

In my platform, the DHCP servers and the VMs are running on different servers.

The patch "make delete_router send delete_port to core_plugin" [1] could be applied to ODL MD to check OF 1.3 rules for gateway ports.
