● Overlapping IP
● Shared Networks
● L3 Routing
● Floating IP
● What's going on behind the scene

5. Overlapping Tenant Network
● source ~/user_demo_one
● quantum net-create net1-user-one
● quantum subnet-create net1-user-one 10.0.0.0/24
● nova boot --image cirros --flavor 1 --nic net-id=<net1-user-one-id> vm1-user-one
● nova boot --image cirros --flavor 1 --nic net-id=<net1-user-one-id> vm2-user-one
● source ~/user_demo_two
● quantum net-create net1-user-two
● quantum subnet-create net1-user-two 10.0.0.0/24
● nova boot --image cirros --flavor 1 --nic net-id=<net1-user-two> vm1-user-two
● nova boot --image cirros --flavor 1 --nic net-id=<net1-user-two> vm2-user-two

6. L3 Routing
● source ~/admin_user
● # create two private networks we want to route between
● quantum net-create privnet1
● quantum subnet-create --name priv1subnet priv1- 10.0.2.0/24
● quantum net-create privnet2
● quantum subnet-create --name priv2 priv2 10.0.3.0/24
● # create a router
● quantum router-create router1
● # connect router to the two private subnets
● quantum router-interface-add router1 priv1subnet
● # note port list adds a port with .1 address to subnet
● nova boot --image cirros --flavor 1 --nic net-id=<privnet1-id> vm-privnet1
● nova boot --image cirros --flavor 1 --nic net-id=<privnet2-id> vm-privnet2
● # login to horizon to confirm route pinging

7. Floating IP
● # create external network
● quantum net-create ext_net -- --router:external=True
● quantum subnet-create ext_net 1.1.1.0/24 --
--enable_dhcp=False
● # connect router to the upstream external network
● quantum router-gateway-set router1 ext_net
● # create some floating ips out of this external network
● quantum floatingip-create ext_net --port_id $VM2_PORT_ID
● quantum floatingip-disassociate <floating_ip_id>
