第4章 Configuring the Overcloud after Creation

The Overcloud requires a IPv6-based Project network for instances. Source the overcloudrc file and create an initial Project network in neutron. For example:

$ source ~/overcloudrc

$ openstack network create default --external --provider-physical-network datacentre --provider-network-type vlan --provider-segment 101

$ openstack subnet create default --subnet-range 2001:db8:fd00:6000::/64 --ipv6-address-mode slaac --ipv6-ra-mode slaac --ip-version 6 --network default

This creates a basic neutron network called default. Confirm the created network with the network list and subnet list commands:

$ openstack network list
$ openstack subnet list
