Dynamic Host Configuration Protocol

  • Include DHCP option 61 in Radius Access Request (MX240, MX480, and MX960 routers)—Starting in Junos OS Release 21.1R1, you can configure DHCP to use the client identifier (DHCP Option 61) in the username that is passed to the external AAA authentication service when the DHCP client logs in. You can also configure options to exclude headers and to use automatic ASCII hex encoding to obtain the preferred string for authentication. This feature is supported for DHCP server and relay in DHCPv4, DHCPv6, and dual stack.
