Introduction to the DHCPv6 Relay Agent
Application Environment
Figure 9 Typical DHCPv6 relay agent application
A DHCPv6 client usually uses a multicast address to contact the DHCPv6 server on the local link to
obtain an IPv6 address and other configuration parameters. As shown in
Figure 9 , if the DHCPv6 server
resides on another subnet, the DHCPv6 client can contact the server via a DHCPv6 relay agent. Thus,
you do not need to deploy a DHCPv6 server on each subnet.
