Group-Specific DHCP Relay Options
You can include the following statements at the [edit forwarding-options dhcp-relay group group-name] hierarchy level to set group-specific DHCP relay agent configuration options. Group-specific statements apply only to the named group of interfaces, and override any global DHCP relay agent settings for the same statement.
Include the statements at the [edit forwarding-options dhcp-relay dhcpv6 group group-name] hierarchy level to configure group-specific options for DHCPv6 relay agent.
- active-server-group—Configure an active server group to apply a common DHCP relay agent configuration to a named group of DHCP server addresses. For information, see Configuring Active Server Groups.
- authentication—Configure the parameters the router (or switch) sends to the external AAA server.
- dynamic-profile—Specify the dynamic profile that is attached to a group of interfaces.
- interface—Specify one or more interfaces, or a range of interfaces, that are within the specified group.
- liveness-detection—Configure bidirectional failure detection timers and authentication criteria for static routes. For more information, see DHCP Liveness Detection Overview.
- overrides—Override the default configuration settings for the extended DHCP relay agent. For information, see Overriding the Default DHCP Relay Configuration Settings.
- relay-agent-interface-id—(DHCPv6 only) Insert the DHCPv6 Relay Agent Interface-ID option (option 18) in DHCPv6 packets destined for the DHCPv6 server.
- relay-option—Configure selective processing, which uses DHCP options in client packets to identify and filter client traffic, and to specify the action DHCP relay agent takes with the traffic. For more information, see Using DHCP Option Information to Selectively Process DHCP Client Traffic.
- relay-option-82—(DHCPv4 only) Enable or disable the insertion of option 82 information in packets destined for a DHCP server. For information, see Enabling and Disabling Insertion of Option 82 Information.
- service-profile—Specify the default subscriber service, (or default profile) which is activated when the subscriber (or DHCP client) logs in and no other service is activated by a RADIUS server or a provisioning server. For more information, see Default Subscriber Service Overview.
