    Configuring Address Assignment on a Broadband Gateway APN

    One of the key roles of the MobileNext Broadband Gateway configured as either a 3G gateway GPRS support node (GGSN) or 4G Packet Data Network Gateway (P-GW) is to assign IP addresses to a mobile device. This topic configures the address assignment parameters for an access point name (APN).

    Before you begin configuring address assignment on a broadband gateway APN, you should have done the following:

    • Configured the chassis of the broadband gateway
    • Configured the interfaces of the broadband gateway
    • Configured the general APN parameters for the specific APN
    • Configured the general Dynamic Host Configuration Protocol (DHCP) parameters for the broadband gateway

    To assign IP addresses to devices accessing the broadband gateway APN, you configure a DHCP IPv4 and IPv6 proxy client based on DHCP profiles. The address pools can be included in or excluded from the APN. You can also configure parameters for static address use and authentication, authorization, and accounting (AAA).

    To configure address assignment on a broadband gateway APN:

    1. Configure address assignment to use AAA on apn-1.
      [edit unified-edge gateways ggsn-pgw MBG1 apn-services apns apn-1 address-assignment]user@host# set aaa
    2. Configure address assignment to allow user equipment to provide a static address that is not verified by AAA on apn-1.
      [edit unified-edge gateways ggsn-pgw MBG1 apn-services apns apn-1 address-assignment]user@host# set allow-static-ip-address no-aaa-verify
    3. Configure AAA to override the address received by the DHCP proxy client for this APN.
      [edit unified-edge gateways ggsn-pgw MBG1 apn-services apns apn-1 address-assignment]user@host# set dhcp-proxy-client aaa-override
    4. Optionally, configure the logical system for the DHCPv4 proxy client profile to use for this APN.
      [edit unified-edge gateways ggsn-pgw MBG1 apn-services apns apn-1 address-assignment]user@host# set dhcpv4-proxy-client-profile logicial-system logicial-system-name

      Note: This is the logical system where the DHCPv4 proxy client profile is defined. If this is not specified, the default logical system is used.

    5. Optionally, configure the address pool name for the DHCPv4 proxy client profile to use for this APN.
      [edit unified-edge gateways ggsn-pgw MBG1 apn-services apns apn-1 address-assignment]user@host# set dhcpv4-proxy-client-profile pool-name pool-name

      Note: This is the name of the address pool sent to the DHCP server.

    6. Configure the profile name for the DHCPv4 proxy client profile to use for this APN.
      [edit unified-edge gateways ggsn-pgw MBG1 apn-services apns apn-1 address-assignment]user@host# set dhcpv4-proxy-client-profile profile-name profile-name

      Note: The DHCPv6 profile parameters must be defined.

    7. Optionally, configure the routing instance for the DHCPv4 proxy client profile to use for this APN.
      [edit unified-edge gateways ggsn-pgw MBG1 apn-services apns apn-1 address-assignment]user@host# set dhcpv4-proxy-client-profile routing-instanceruiting-instance-name

      Note: This is the routing instance where the DHCPv4 proxy client profile is defined. If this is not specified, the default routing instance is used.

    8. Optionally, configure the logical system for the DHCPv6 proxy client profile to use for this APN.
      [edit unified-edge gateways ggsn-pgw MBG1 apn-services apns apn-1 address-assignment]user@host# set dhcpv6-proxy-client-profile logicial-system logicial-system-name

      Note: This is the logical system where the DHCPv6 proxy client profile is defined. If this is not specified, the default logical system is used.

    9. Optionally, configure the address pool name for the DHCPv6 proxy client profile to use for this APN.
      [edit unified-edge gateways ggsn-pgw MBG1 apn-services apns apn-1 address-assignment]user@host# set dhcpv6-proxy-client-profile pool-name pool-name

      Note: This is the name of the address pool sent to the DHCP server.

    10. Configure the profile name for the DHCPv6 proxy client profile to use for this APN.
      [edit unified-edge gateways ggsn-pgw MBG1 apn-services apns apn-1 address-assignment]user@host# set dhcpv6-proxy-client-profile profile-name profile-name

      Note: The DHCPv6 profile parameters must be defined.

    11. Optionally, configure the routing instance for the DHCPv4 proxy client profile to use for this APN.
      [edit unified-edge gateways ggsn-pgw MBG1 apn-services apns apn-1 address-assignment]user@host# set dhcpv6-proxy-client-profile routing-instancerouting-instance-name

      Note: This is the routing instance where the DHCPv4 proxy client profile is defined. If this is not specified, the default routing instance is used.

    12. Configure the IPv4 address pool or group for this APN.
      [edit unified-edge gateways ggsn-pgw MBG1 apn-services apns apn-1 address-assignment]user@host# set inet-pool pool pool-name user@host# set inet-pool group group-name

      Note: The address pool or group referenced must be defined.

    13. Configure one or more IPv4 address pools to exclude for this APN.
      [edit unified-edge gateways ggsn-pgw MBG1 apn-services apns apn-1 address-assignment]user@host# set inet-pool exclude-pools pool-name(s)

      Note: The address pool or group referenced must be defined.

    14. Configure the IPv6 address pool or group for this APN.
      [edit unified-edge gateways ggsn-pgw MBG1 apn-services apns apn-1 address-assignment]user@host# set inet6-pool pool pool-name user@host# set inet6-pool group group-name

      Note: The address pool or group referenced must be defined.

    15. Configure one or more IPv6 address pools to exclude for this APN.
      [edit unified-edge gateways ggsn-pgw MBG1 apn-services apns apn-1 address-assignment]user@host# set inet6-pool exclude-v6pools v6pool-name(s)

      Note: The address pool or group referenced must be defined.

    16. Optionally, configure AAA to override local address assignment for this APN.
      user@host# set local aaa-override
