    Enable and Configure IPv6 Networking and IP Pools in Your Prisma Access Infrastructure

    Learn how to enable and configure IPv6 networking and IP pools in your Prisma Access infrastructure.
    Where Can I Use This?
    What Do I Need?
    • Prisma Access (Managed by Strata Cloud Manager)
    • Prisma Access (Managed by Panorama)
    • Prisma Access
       license version 2.2 Preferred and later
    For any Prisma Access deployment, you need to enable IPv6 globally and specify an IPv6 subnet in your Infrastructure Subnet so that Prisma Access can establish an IPv6 network infrastructure between your remote network locations, mobile users, and service connections. To do so, complete the following steps.

    Cloud Management

    1. Select
      Manage
      Service Setup
      Prisma Access
       and select the gear icon to edit the Settings.
      If you're using Strata Cloud Manager, go to
      Workflows
      Prisma Access Setup
      Prisma Access
      .
    2. Select the check box to
      Enable
       IPv6 for Internal Traffic.
      Enabling or disabling IPv6 results in a brief traffic interruption (up to 120 seconds) while the dataplane prepares to accept or reject IPv6 routes on the Prisma Access backbone. We recommend that you push this configuration change during a maintenance window or during off-peak hours.
      If you need to delete IPv6, delete all configuration (including for mobile users, remote network, and service connections as applicable) before deselecting the
      Enable
       IPv6 for Internal Traffic check box.
    3. Specify an
      IPv6
       infrastructure subnet and an
      Infrastructure BGP AS
      .
      • Specify a minimum subnet of /96.
      • You must also enter an IPv4 subnet; Prisma Access requires IPv4 and IPv6 subnets in its network infrastructure to use IPv6. See Prisma Access Infrastructure Management for details.
      • Palo Alto Networks recommends that you use private (not public) IPv4 and IPv6 addresses.
      • Do not use IPv6 link local addresses (fe80::/10).
    4. Enter the
      Infrastructure BGP AS
       you want to use within the Prisma Access infrastructure.
      If you want to use dynamic routing to enable Prisma Access to dynamically discover routes to resources on your remote networks and HQ/data center locations, specify the autonomous system (AS) number. If you do not supply an AS number, the default AS number 65534 will be used.
    5. If you haven't done so already, consider adding Internal DNS Servers to enable Prisma Access to resolve your internal domains to access services, such as LDAP and DNS server,s on your corporate network.
    6. (
      Mobile User Deployments Only
      ) Add IPv6 IP address pools for your Mobile Users—GlobalProtect deployment.
      A Mobile Users—GlobalProtect deployment requires IP address pools. Both IPv4 and IPv6 IP address pools are required to enable IPv6 functionality. You apply IPv4 addresses at a regional or Worldwide level; you apply IPv6 addresses at a Worldwide level. Specify a minimum /80 subnet.
      Prisma Access subdivides the Worldwide IPv6 addresses using the following method:
      • Prisma Access assigns each location (gateway) a pool from a /112 subnet. Because each GlobalProtect connection uses one IP address from the pool, this allocation allows over 65,000 available IPv6 addresses to be assigned to users’ endpoints per location.
        If you experience an auto-scale event (if a large number of users log in to a single Prisma Access location), Prisma Access can add another location with another /112 subnet.
      • When you enable a location to use IPv6, Prisma Access assigns an IPv6 address pool to the region to which the location belongs, and divides up the pool between the total number of regions that have IPv6 enabled.
      Do not use local-link addresses (fe80::/10) in an IP address pool.
      1. Select
        Workflows
        Prisma Access Setup
        GlobalProtect
         and select the gear icon to edit the Infrastructure Settings.
      2. In the Client IP Pools section, select a
        Region
         or select
        Add IP Portal
        .
      3. Enter an
        IPv6 Address Pool
        .
        • You must enter both IPv4 and IPv6 IP addresses for mobile users. Prisma Access requires IPv4 and IPv6 addresses to support its internal infrastructure when using IPv6.
        • Enter a minimum IPv6 subnet of /80.
        • Prisma Access subdivides each subnet per region.
    7. Save
       and
      Push Config
      .
    8. Select
      Workflows
      Prisma Access Setup
      Prisma Access
       and make a note of the following IPv6 addresses in your Infrastructure Settings:
      • Captive Portal Redirect IP Addresses
        —Used with Authentication Portal-based User-ID address mapping
      • Tunnel Monitor IP Address
        —Used for Tunnel Monitoring
      Because GlobalProtect mobile users require an IPv4 address for the VPN tunnels, loopback addresses, whose IP addresses are taken from the Infrastructure Subnet, still use IPv4 addresses.
