I want to add routes different from default to foating pool like this. Is it possible?
Destination Gateway Genmask 0.0.0.0 192.168.122.1 0.0.0.0 192.168.2.0 192.168.122.2 255.255.255.0 192.168.122.0 0.0.0.0 255.255.255.0
With Havana(need to check! maybe it is trunk) you can add static routes to a router. Devstack creates a router with two subnets connected:
vagrant@devstack:~/devstack$ neutron subnet-list -c name -c cidr
+----------------+-----------------+
| name | cidr |
+----------------+-----------------+
| public-subnet | 172.24.4.224/28 |
| private-subnet | 10.0.0.0/24 |
+----------------+-----------------+
vagrant@devstack:~/devstack$ neutron router-update router1 \
--routes type=dict list=true destination=100.0.0.0/24,nexthop=172.24.4.230
Updated router: router1
note: you need have the admin role to do that.
vagrant@devstack:~/devstack$ neutron router-list -c name -c routes
+---------+------------------------------------------------------------------+
| name | routes |
+---------+------------------------------------------------------------------+
| router1 | [{u'nexthop': u'172.24.4.230', u'destination': u'100.0.0.0/24'}] |
+---------+------------------------------------------------------------------+
vagrant@devstack:~/devstack$ sudo ip netns exec \
qrouter-c29357dc-416f-4712-9c3b-ce697b889bd7 route -n

I have only found this solution.
