DHCPv6 Relay Agent Overview
The DHCPv6 relay agent enhances the extended DHCP relay agent by providing support in an IPv6 network. The DHCPv6 relay agent passes messages between the DHCPv6 client and the DHCPv6 server, similar to the way DHCP relay agent supports an IPv4 network.
When a DHCPv6 client logs in, the DHCPv6 relay agent uses the AAA service framework to interact with the RADIUS server to provide authentication and accounting. The RADIUS server, which is configured independently of DHCP, authenticates the client and supplies the IPv6 prefix and client configuration parameters, such as session timeout and the maximum number of clients allowed per interface.
 | Note: The PTX Series Packet Transport Routers do not support authentication for DHCPv6 relay agents. |
The DHCPv6 relay agent is compatible with the extended DHCP local server and the extended DHCP relay agent, and can be enabled on the same interface as either the extended DHCP local server or DHCP relay agent.
To configure the DHCPv6 relay agent on the router (or switch), you include the dhcpv6 statement at the [edit forwarding-options dhcp-relay] hierarchy level.
You can also include the dhcpv6 statement at the following hierarchy levels:
- [edit logical-systems logical-system-name forwarding-options dhcp-relay]
- [edit logical-systems logical-system-name routing-instances routing-instance-name forwarding-options dhcp-relay]
- [edit routing-instances routing-instance-name forwarding-options dhcp-relay]
