Hi,

how does one add other than default gw routes to quantum router?

Our external network has two switches:

a) .1 as gateway to company intranet 10.0.0.0/8
b) .2 as gateway to internet

and quantum router has port with 10.1.1.7/26 ip in external net. Now, 
how do I tell the router to forward all outgoing packets to correct 
gateways? How do you add next hops to quantum routers?

I would assume it should be done by adding additional routes to quantum 
routers network namespace.

sudo ip netns exec <qrouter-namespace> ip r add 10.0.0.0/8 via 10.1.1.1

but it didn't work, and I suppose I should not (and I don't want to) 
modify those tables manually anyhow. Adding host_routes to quantum 
network only affected the dhcp server in the network, instead of adding 
routes into any existing namespace:

  quantum subnet-update net_out --host_routes type=dict list=true 
destination=10.0.0.0/8,nexthop=10.1.1.1

Our quantum external network is configured like this:

$ quantum net-show 2f1758e6-5c73-4662-bdb8-a74ff2c2e440
