I used packstack to install Havana (ovs+gre).Firstly, I created an external network--“ex-net"(10.50.9.0/24) and an internal-network--"in-net"(10.0.2.0/24),then created a router-

-"route-1", set the "route-1" gateway useing "ex-net"and added an interfaces using "in-net"; launch a instance, fixed a floating ip to a instance, so this instance got a floating ip--"10.50.9.231",at this time I can see from the Dashboard the "ex-net" has 3 ports:10.50.9.230(network:router_gateway),10.50.9.232(network:dhcp),10.50.9.231(network:floatingip).

[root@controller-2 ~]# ip netns list qdhcp-ddcbc547-dfe5-4215-b034-5fcb20707340 qrouter-e40b75c3-ed14-4a7f-a6d8-72528c64cf82 qdhcp-e638ff4a-05e0-4107-8d17-47aac3b32d3a

But when a add another router--"route-2", I used the command : ip netns list, it returned the same result as above. the new router--"route-2" didn't work. when I unset the gateway of "route-1", and set it's gateway using another external-network--"ex-net-2", I used the command: ip netns exec qrouter-e40b75c3-ed14-4a7f-a6d8-72528c64cf82 ifconfig, I find that the inet addr of qg-d6312667-d3 didn't change ,it's the same as above. my instance cannot access Internet,

I reset the gateway of "route-1",using "ex-net",and fixed a floating ip to my instance(10.50.9.230).see "ex-net" frome Dashboard,it's different as the first time I used it,3 ports now are as follow: has 3 ports:10.50.9.231(network:router_gateway),10.50.9.232(network:dhcp),10.50.9.230(network:floatingip).used the command: ip netns exec qrouter-e40b75c3-ed14-4a7f-a6d8-72528c64cf82 ifconfig,it's also the same as above. and ...
