This article introduces you how to connect instance to second_local_net, the content is very detailed, interested friends can refer to, hope to be helpful to you.

We will verify the connectivity of the two local network.

Launch's new instance "cirros-vm3", the network chooses second_local_net.

The IP assigned to cirros-vm3 is 172.16.1.102.

The cirros-vm3 is schedule to the control node, and the corresponding tap device is tap5395d19b-ed.

The console shows that cirros-vm3 has successfully obtained the IP address 172.16.1.102 from DHCP.

But cirros-vm3 cannot Ping to cirros-vm1.

This is to be expected, because cirros-vm3 and cirros-vm1 are located in different local network, there is no connection between them, and even if they are both on the same host, they cannot communicate.

The knowledge points of local network have been discussed here, so let's make a summary.

1. Instance located on the same local network can communicate.

two。 Instance at different local network cannot communicate.

3. A local network can only be located on one physical node, not across nodes.

Although local network is rarely used in practical applications, the significance of learning local network is:

Local network can be used as a starting point for learning more complex network types such as flat, vlan, vxlan, etc., and reduce the learning difficulty of Neutron.

On how to connect instance to second_local_net to share here, I hope the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
