Deploy another instance and Local Network-5 minutes a day to play with OpenStack (131)

The previous section deployed CIRROS-VM1 to First_local_net, and today we will deploy CIRROS-VM2 to the same network and create second_local_net.

connecting a second instance to first_local_net

In the same way launch instance "CIRROS-VM2", the assigned IP is 172.16.1.4.

The CIRROS-VM2 is also schedule to the control node, and the output of Ovs-vsctl show is as follows:

CIRROS-VM2 for the TAP device is tapddbbb728-93.

From CIRROS-VM2 can Ping the IP address of the CIRROS-VM1 172.16.1.3.

The network structure of the current host is as follows:

Two instance are hung on the br-int and can communicate with each other.

Create a second local network

To analyze the connectivity of the local network, we create a "second_local_net". Most properties of second_local_net are the same as first_local_net, except that the IP pool range is 172.16.1.101-172.16.1.200

Second_local_net's DHCP device is also ready.

The tap device for DHCP is tap2c1b3c58-4e and is already connected to the Br-int.

The next section deploys instance to Second_local_network and analyzes the connectivity of two local network.
