How to setup floating ip with Neutron

(See also https://github.com/Juniper/contrail-controller/wiki/Simple-Gateway)

Add This on LocalRC

CONTRAIL_VGW_INTERFACE=vgw
CONTRAIL_VGW_PUBLIC_SUBNET=10.99.99.0/24 # replace with your floating IP range
CONTRAIL_VGW_PUBLIC_NETWORK=default-domain:admin:public:public

Setup public network in neutron

. openrc admin admin
neutron net-create public
public_id=`neutron net-list | awk '/public/{print }'`
neutron subnet-create --name public-subnet1 $public_id $CONTRAIL_VGW_PUBLIC_SUBNET --disable-dhcp

Setup floating ip pool in contrail

   python /opt/stack/contrail/controller/src/config/utils/create_floating_pool.py --public_vn_name default-    domain:admin:public --floating_ip_pool_name floatingip_pool
   python /opt/stack/contrail/controller/src/config/utils/use_floating_pool.py --project_name default-domain:admin --floating_ip_pool_name default-domain:admin:public:floatingip_pool

Setup Security Group

. openrc admin demo
nova secgroup-list
nova secgroup-list-rules default
nova secgroup-add-rule default tcp 22 22 0.0.0.0/0
nova secgroup-add-rule default icmp -1 -1 0.0.0.0/0
nova secgroup-list-rules default

Setup floating ip

neutron floatingip-create $public_id
neutron floatingip-associate $floatingip_id $port_id

Test it

neutron floatingip-show $floatingip_id ssh cirros@$floatingip_ip
