4.4. Configuring Satellite for UEFI HTTP Boot Provisioning in an IPv6 Network

Use this procedure to configure Satellite to provision hosts in an IPv6 network with UEFI HTTP Boot provisioning.

Prerequisites

Ensure that your clients can access DHCP and HTTP servers.
Ensure that the UDP ports 67 and 68 are accessible by clients so clients can send DHCP requests and receive DHCP offers.
Ensure that the TCP port 8000 is open for clients to download files and Kickstart templates from Satellite and Capsules.
Ensure that the host provisioning interface subnet has an HTTP Boot Capsule, and Templates Capsule set. For more information, see Adding a Subnet to Satellite Server in the Provisioning Guide.
Navigate to Administer > Settings > Provisioning and ensure that the Token duration setting is not set to 0. Satellite cannot identify clients that are booting from the network by a remote IPv6 address because of unmanaged DHCPv6 service, therefore provisioning tokens must be enabled.

Procedure

You must disable DHCP management in the installer or not use it.
For all IPv6 subnets created in Satellite, set the DHCP Capsule to blank.
Optional: If the host and the DHCP server are separated by a router, configure the DHCP relay agent and point to the DHCP server.
On Satellite or Capsule from which you provision, update the grub2-efi package to the latest version:
```
# satellite-maintain packages install grub2-efi
```
Synchronize the Red Hat Enterprise Linux 8 kickstart repository.
