DHCPv6 relay agent configuration

Introduction to the DHCPv6 relay agent

Application environment

Figure 55 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
resides on another subnet, the DHCPv6 client can contact the server via a DHCPv6 relay agent, so you
do not need to deploy a DHCPv6 server on each subnet.

Operation of DHCPv6 relay agent

Figure 56 Operating process of a DHCPv6 relay agent
Figure 56 shows how the DHCPv6 client obtains an IPv6 address and other network configuration
parameters from the DHCPv6 server through the DHCPv6 relay agent, using the process of rapid
assignment involving two messages.
The DHCPv6 client sends a Solicit message containing the Rapid Commit option to the multicast
1.
address FF02::1:2 of all the DHCPv6 servers and relay agents.
