After we have configured the Neutron network node, we can go ahead and configure our compute nodes to use Neutron networking service.
When the controller and Neutron network node are ready, we can configure Nova-Compute node to use Neutron for networking. We will configure Neutron access to the message broker. Then, we will configure Neutron to use ML2 plugin with GRE tunneling segmentation.
Run the following commands on
net.ipv4.conf.all.rp_filter=0 net.ipv4.conf.default.rp_filter=0 and apply the new configuration: [root@compute1 ~]# sysctl -p
