Configuring OpenStack VTEP gateways

Overview

OpenStack VTEP is an ICOS application that provides OpenStack tenants access to physical devices that are plugged into a properly configured ICOS switch.

This section lists steps necessary for the proper configuration of ICOS switches that are used with OpenStack VTEP.

# ip routing

Here is an example output generated by show running-config on a switch that is properly configured:

(Routing) #show running-config

In the above, the controller is plugged into 0/5 and the compute node is plugged into 0/6.

Physical devices for tenants are cabled to 0/29 (demo1) and 0/30 (demo2).
