I am going to close this bug as invalid. The static route to router
interface seems useless. Bug according to bug 1460793, it is for windows
VM. I think the bug description in that bug can explain why the route is
needed.

** Changed in: neutron
       Status: Confirmed => Invalid

Title:
  after adding network port to router , static route is not removed from
  options- metadata- enable_isolated_metadata = True

Status in neutron:
  Invalid

Bug description:
  metadata- enable_isolated_metadata = True: After attaching network to
  router and restarting dhcp agent, static route is not removed from
  options

  In /etc/neutron/dhcp_agent.ini:
  force_metadata = False
  enable_isolated_metadata = True
  enable_metadata_network = False

  
  The commands show that the networl port is attached to the router r1:

  Here we will see that the static route still exists:

  [root@overcloud-controller-2 ~]# 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[root@overcloud-controller-2 ~]# 

  
  With enable_isolated_metadata = True configuration - When attaching network port to a neutron router, Static route in /var/lib/neutron/NETID/opts should be removed ( no agent restrt should be needed - https://bugs.launchpad.net/neutron/+bug/1549860 ) 

  
  Liberty

  Reproducible.
