[Bug 1840737] Re: Neutron create IPv6 subnet error. Gateway is not valid on subnet.
A really old neutron version.
But anyway, IMO, you met this bug: https://bugs.launchpad.net/neutron/+bug/1682094
This is the error comes from:
https://github.com/openstack/neutron/blob/master/neutron/db/db_base_plugin_v2.py#L611-L616
According to the exception, I did the following tests:
>>> ip = netaddr.IPAddress("2a0a:4180::2")
>>> net = netaddr.IPNetwork("2a0a:4180::2/127")
>>> (ip in net and (ip == net.network or (net.version == 4 and ip == net[-1])))
True
>>> ip == net.network
True
>>> (ip in net and (net.version == 4 and ip in (net.network, net[-1]))) <---- current check
False
>>> ip in net
True
So you should update this function to such style:
https://github.com/openstack/neutron/blob/master/neutron/ipam/utils.py#L40-L51
Since this verison 9.1.1 of neutron had been marked as EOL long time
ago, I will marked this bug to invalid.
