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.

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:

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 -
