How to deploy an instance and Local Network
Today, I would like to talk to you about how to deploy an instance and Local Network. Many people may not know much about it. In order to make you understand better, the editor has summarized the following for you. I hope you can get something from this article.
Today we will deploy cirros-vm2 to the same network and create a second_local_net.
Connect the second instance to first_local_net
Launch instance "cirros-vm2" in the same way, with an assigned IP of 172.16.1.4.
The cirros-vm2 is also schedule to the control node, and the output of ovs-vsctl show is as follows:
The tap device for which cirros-vm2 is used is tapddbbb728-93.
From cirros-vm2, it is possible to Ping the IP address 172.16.1.3 of cirros-vm1.
The current network structure of the host is as follows:
Both instance are attached to the br-int and can communicate with each other.
Create a second local network
To analyze the connectivity of local network, we create another "second_local_net".
Most of the properties of second_local_net are the same as first_local_net, except that the range of IP pool is 172.16.1.101-172.16.1.200
Second_local_net 's DHCP device is also ready.
The tap device corresponding to the DHCP is tap2c1b3c58-4e and is already connected to the br-int.
