Description

For the relay-agent-interface-id statement, specify that in dual-stack environments, the DHCPv6 relay agent uses an Interface-ID option (option 18) that is based on the DHCPv4 relay agent information option (option 82). When you include this statement, the DHCPv6 relay agent checks for the option 82 Agent Circuit-ID suboption (suboption 1) and inserts it into the outgoing RELAY-FORW message.

For the relay-agent-remote-id statement, specify that in dual-stack environments, the DHCPv6 relay agent uses a Remote-ID option (option 37) that is based on the DHCPv4 relay agent information option (option 82). When you include this statement, the DHCPv6 relay agent checks for the option 82 Remote-ID suboption (suboption 2) and inserts it into the outgoing RELAY-FORW message.

Options

strict

(Optional) The router drops Solicit messages that do not include a DHCPv4 Remote-ID (option 82 suboption 2). If you do not specify the strict keyword, the router sends the RELAY-FORW message without adding option 37.

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 13.2.

Support at the [...relay-agent-remote-id] hierarchy level introduced in Junos OS Release 15.1.
