Description

Specify that the jdhcpd process keeps the incoming interface ID and prepends the ID with the locally generated ID (in the format, generated-id + incoming-id) before sending the leasequery packet to the DHCPv6 server.

This configuration is required for leasequery and bulk leasequery operations when subscriber authentication is based on the interface ID, and enables leasequery and bulk leasequery to restore the agent circuit identifier/agent remote identifier (ACI/ARI) pair and to use the interface ID to authenticate subscribers.

Required Privilege Level

interface—To view this statement in the configuration.

interface-control—To add this statement to the configuration.

Release Information

Statement introduced in Junos OS Release 16.1.
