Configure Default Forwarding Options for the DHCPv4 Wholesale Network Solution

 

You can use DHCP Relay, DHCP Relay Proxy, or DHCP Local Server configuration in a DHCP wholesale network. DHCP configuration is defined at the [edit forwarding-options] hierarchy level.

Note

The configuration for this wholesale solution uses DHCP Relay.

To configure DHCPv4 Relay forwarding options:

  1. Access the [edit forwarding-options dhcp-relay] hierarchy.
  2. Specify that you want to configure authentication options and use external AAA authentication services.
  3. (Optional) Configure a password that authenticates the username to the external authentication service.

    See Example-Configuring DHCP with External Authentication Server.

  4. (Optional) Configure optional features to create a unique username.

    See Creating Unique Usernames for DHCP Clients.

  5. Specify the default dynamic profile that you want to attach to all DHCP subscriber that access the router.
  6. Specify any overrides for the default DHCP Relay configuration.

    See Overriding the Default DHCP Relay Configuration Settings.

  7. Configure a named server group for default (wholesaler) DHCP server access.
  8. Specify the DHCP server address for the default (wholesale) group.
  9. Specify the default (wholesale) group as the active server group.
  10. Configure a group you can use to define the wholesale DHCP access interface.
  11. Specify the default (wholesale) interface that all DHCP subscribers use when first accessing the router.
  12. Configure a group you can use to define a retail DHCP interface.
  13. Specify the logical interface the DHCP subscribers use once redirected.
  14. Repeat steps 12 and 13 for other retailer groups.

    In this solution example, you configure another group name of “Retailer2_Group” and specify ge-2/3/0.3 for the logical interface.

  15. (Optional) Configure any passwords that authenticate the username to the external authentication service for any of the groups that you created.

    See Example-Configuring DHCP with External Authentication Server.

  16. (Optional) Configure optional features to create a unique username for any of the groups that you created.

    See Creating Unique Usernames for DHCP Clients.

  17. (Optional) Specify any overrides for any of the DHCP Relay group configurations that you created.

    See Overriding the Default DHCP Relay Configuration Settings.
