Hi,
I have been following this guide,
https://docs.openstack.org/ocata/install-guide-rdo/launch-instance-networks-provider.html
and got to a point where I have created the following subnet
openstack subnet create --network provider --allocation-pool
start=130.217.238.20,end=130.217.238.250 --dns-nameserver 130.217.240.32
--gateway 130.217.238.251 --subnet-range 130.217.238.0/24 provider
>From a OpenStack perspective this seems to have worked but based on the
output of the router port list below I believe that if all networking were
working correctly I should be able to ping 130.217.238.27 from my
controller is this correct ? Currently this isn't working
# neutron router-port-list router
neutron CLI is deprecated and will be removed in the future. Use openstack
CLI instead.

Looking in linuxbridge-agent.log I see entries like the one below. Does
anyone have suggestions as to how I fix this issue?

I have found
https://ask.openstack.org/en/question/92057/after-creating-selfservice-subnet-neutron-linux-bridge-log-shows-error-rtnetlink-answers-permission-denied/
and so tried disabling ipv6 via sysctl.conf but this doesn't seem to have
made any difference.
Thanks for any advice or suggestions you can offer.
Here is some other information that may be useful
