Networking

Firstly, we need to ensure that we have the right networks prepared for use in the Hypervisor. These networks will be used to host both the Management and Hosted clusters.

To configure these networks, we will use the following kcli command:

kcli create network -c 2620:52:0:1305::0/64 -P dhcp=false -P dns=false --domain hypershiftbm.lab --nodhcp ipv6

Where:

  • -c remarks the CIDR used for that network
  • -P dhcp=false configures the network to disable the DHCP, this will be done by the dnsmasq we've configured before.
  • -P dns=false configures the network to disable the DNS, this will be done by the dnsmasq we've configured before.
  • --domain sets the domain to search into.
  • ipv6 is the name of the network that will be created.

This is what the network will look like once created:

[root@hypershiftbm ~]# kcli list network
