Description Alexander Stafeyev 2016-03-07 14:22:13 UTC 
Description of problem:
metadata- enable_isolated_metadata = True: After attaching network to router and restarting dhcp agent, static route is not removed from /var/lib/neutron/NID/opts

Version-Release number of selected component (if applicable):
[root@overcloud-controller-2 ~]# rpm -qa | grep neutr
openstack-neutron-common-7.0.1-10.el7ost.noarch
openstack-neutron-ml2-7.0.1-10.el7ost.noarch
openstack-neutron-openvswitch-7.0.1-10.el7ost.noarch
python-neutron-lbaas-7.0.0-2.el7ost.noarch
openstack-neutron-7.0.1-10.el7ost.noarch
openstack-neutron-metering-agent-7.0.1-10.el7ost.noarch
python-neutron-7.0.1-10.el7ost.noarch
openstack-neutron-lbaas-7.0.0-2.el7ost.noarch
python-neutronclient-3.1.0-1.el7ost.noarch


How reproducible:
100%

Steps to Reproduce:
1. Configure  enable_isolated_metadata = True in /etc/neutron/dhcp-agent.ini
2. Create Internal net and subnet. 
3. See there is a static route to 169.254.169.254 in dhcp options- 
cat /var/lib/neutron/dhcp/107277c1-ba33-4e50-93b2-750c8bc594a6/opts
tag:tag0,option:dns-server,10.35.28.28
tag:tag0,option:classless-static-route,169.254.169.254/32,192.168.2.1,0.0.0.0/0,192.168.2.1
tag:tag0,249,169.254.169.254/32,192.168.2.1,0.0.0.0/0,192.168.2.1
tag:tag0,option:router,192.168.2.1

4. Create a router. Attach network port to a router. Restart dhcp agent. 


Actual results:
the static route to 169.254.169.254 still exists

Expected results:
the static route to 169.254.169.254 should be removed.

Duplicate of upstream bug. This isn't specific to OSP, Director, RHEL or anything like that, so no need to track it specifically in RHBZ.
