No, there is no other way to add static routes to the dvr router. I 
don't have any DVR deployment now to check it but IIRC route should be 
added in the qrouter namespace in the compute nodes where router 
exists. If it's not there please check logs of the l3-agent on those 
hosts, maybe there are some errors there.
