I recently installed opensstack with RDO:packstack on tow node. .

One controller node with nova, neutron, glance, swift, cinder ... One compute node with nova-compute.

Almost everything is working fine, I can create VM, network, router. VM can ping each other and routing is owrking just fine.

But whe i try to connect VMS to the external network by creating a public network and setting up the gateway in the router, the router interface stay down so i can't acces external network. But I can assign Floating IP to VM Here are the command I used :

neutron net-create public --router:external=True
neutron subnet-create public --name publicSub --enable_dhcp=False --allocation-pool start=,end= --gateway=
neutron router-gateway-set RTR01 public

Im using GRE tunnel for traffic betwenn the compute and the controller node.

EDIT: I solved my problem. I just add on of my controlelr node's interface to the br-ex using ovs-vsctl add-port br-ex eth1 Everything is now working.

Am I missing something ?
