Title:
  DVR: Static routes are not configured in snat-namespase for DVR
  Routers

Status in neutron:
  Invalid

Bug description:
  Static routes are not configured in snat-namespace for DVR routers.

  Steps to reproduce:
  1. Create Network
  2. Create Subnet
  3. Create Router
  4. Add interface to Router
  5. Set gateway for the Router
  6. Add a static route (next hop to the Router)
  7. Go check the 'snat-namespace' if the static routes are configured in there.

  stack@ubuntu-ctlr:~/devstack$ neutron router-update router2-alt-demo --route destination=10.3.0.0/24,nexthop=192.168.100.20
  neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead.
  Updated router: router2-alt-demo
