Configuring Neutron to use a GRE type driver
As described earlier, tunneled networks can also be implemented using the Generic Routing Encapsulation (GRE) protocol. GRE is a general-purpose point-to-point encapsulation protocol. The GRE header contains a 32-bit key which is used to identify a flow or virtual network in a tunnel.
This recipe shows you how to configure the OpenStack Neutron in order to use GRE for virtual networking.
Getting ready
For this recipe, we will need the following information:
- An SSH-based access to the OpenStack controller node
- The IP address for the tunnel endpoint
- A range of tunnel IDs
How to do it…
The following steps will show you how to configure the GRE type driver for the ML2 plugin:
- With the appropriate credentials, SSH ...
