    Release Information

    Statement introduced in Junos OS Release 8.0.

    Description

    Enable the DHCP relay agent information option which allows DHCP to forward information from clients on different VRF routing instances. The functionality is described in RFC 3046, DHCP Relay Agent Information Option. For the Junos OS implementation, the DHCP option number is 82, and the suboption ID is 1. The suboption length is the length required to contain an interface name in addition to the terminating null character. The overall option length is the suboption length plus 2 bytes (for the option header). The DHCP relay agent information option is only present on packets sent between the relay and the DHCP server.
