Bug Description

If a user creates a topology involving multiple routers such as this:

```
              ======================================
                  | net1 | |
                 (X) router1 [dhcp ns] (X) router2
                  | |
  ===================== =========================
       | net2 | net3
   [dhcp ns] [dhcp ns]
```

A ping between the DHCP namespaces on net2 and net3 fails. I've attached a script to generate this environment including static routes on router1 and router2 to facilitate testing. I've verified this topology works as expected on using ML2 with LinuxBridge.

Thanks for the script to reproduce the issue. If this works with ML2/LB, we should look into it. I'm assuming ML2/OVS works as well.

I will validate the behavior with ml2/ovs, and this is also related to another bug on behavior of static routes that i am looking into

Hi Ramu, support for static routes was completed under https://bugs.launchpad.net/networking-ovn/+bug/1539347, but this bug still appears to exist. Do you know what else is left to do for static routes?

I believe this has been fixed long ago, marking it as such but please re-open if it's not the case.
