[Yahoo-eng-team] [Bug 1505316] Re: compute port lose fixed_ips on restart l3-agent if subnet is prefix delegated
https://bugs.launchpad.net/neutron/+bug/1570122 is not related to this bug. Bug
1505316 is about
1) ipam deleting IPv4 address while adding IPV6 PD subnet to fixed_ips
2) ipam not adding PD subnet for ip allocation
So IMHO, we can close this bug(1505316), and can have separate bugs for any
other IPv6 PD related issues.

compute port lose fixed_ips on restart l3-agent if subnet is prefix

Fix Released
Bug description:
I've created two networks: net04_ext and slaac-auto. First is
dualstack public external network and second is tenant network with
static private IPv4 subnet and prefix delegated IPv6 subnet.
I have ISC DHCPv6 prefix delegation server, that serves GUA's:

I have a router named slaac-router, that connects slaac-auto to
net04_ext. Prefix 2001:470:739e:fefe::/64 was automatically delegated
by prefix delegation.

I have an instance in slaac-auto network.
When I've restarted neutron-l3-agent, router has rebind its GUA
address, but instance lost both IPv4 and IPv6 fixed_ips.

To reproduce:
1. Setup OpenStack with prefix delegation
2. Create public dualstack network
3. Create private network with prefix delegated subnet
4. Create router and hook it up to new subnets
5. Create instance
6. Restart neutron-l3-agent
7. Check out instance fixed_ips (both in nova and neutron)
