      I think "Configuring IPv6 networking for the overcloud" document[1] should have the same section as "Configuring the undercloud for bare metal provisioning over IPv6" [2].
      It's difficult for users to find the document[2] when users want to enable IPv6 on their provisioning network. The document[1] is easier to find when we want to enable IPv6.

      [1]https://docs.redhat.com/en/documentation/red_hat_openstack_platform/17.1/html-single/configuring_ipv6_networking_for_the_overcloud/index

      [2]https://docs.redhat.com/en/documentation/red_hat_openstack_platform/17.1/html/customizing_your_red_hat_openstack_platform_deployment/assembly_customizing-networks-for-the-rhosp-environment#proc_configuring-the-undercloud-for-bare-metal-provisioning-over-ipv6_custom-undercloud-networking

      Additionally, I believe we should describe when we should set "enable_routed_networks" to true or false. The following statement in doc[2] is not enough.

      Specify whether or not the undercloud should create a router on the provisioning network:
      [DEFAULT]
      ...
      enable_routed_networks: <true/false>
      ...
      - Replace <true/false> with true to enable routed networks and prevent the undercloud creating a router on the provisioning network. When true, the data center router must provide router advertisements.
      - Replace <true/false> with false to disable routed networks and create a router on the provisioning network.
      

      How about the following modification idea?

      Specify whether or not the undercloud should create a router on the provisioning network:
      
      [DEFAULT]
      ...
      enable_routed_networks: <true/false>
      ...
      - Replace <true/false> with true to enable routed networks and prevent the undercloud creating a router on the provisioning network. If a external data center router is attached to the provisioning network, this should be set to true. When true, the data center router must provide router advertisements and also M and O flag settings of the data center router must be consistent with the ipv6_address_mode setting.
      - Replace <true/false> with false to disable routed networks and create a router on the provisioning network. If external data center routers are not attached to the provisioning network, this should be set to true.
