5.5.1 Example for Configuring DHCPv6 Relay

This section provides a configuration example of DHCPv6 relay.
Networking Requirements
As shown in
is 3000::3/64. The DHCPv6 client and the DHCPv6 server are on different links; therefore, a
DHCPv6 relay agent is required to forward DHCPv6 messages.
It is required that the Switch should function as the DHCPv6 relay agent to forward DHCPv6
messages exchanged between the DHCPv6 client and the DHCPv6 server. In addition, the
Switch functions as the gateway device of the network at 2000::/64. By specifying the M flag
bit and O flag bit in RA messages, hosts on the network are enabled to obtain IPv6 addresses
and other network configuration parameters through DHCPv6.

Configuration Roadmap
The configuration roadmap is as follows:
1.
Issue 01 (2012-03-15)
Run the display dhcpv6 relay [ interface interface-type interface-number ] command to
check the configuration about the interface enabled with the DHCPv6 relay function.
Run the display dhcpv6 relay statistics [ interface interface-type interface-number ]
command to check the statistics about DHCPv6 messages passing through the DHCPv6
relay agent.
Figure 5-3, the DHCPv6 client address is 2000::/64 and the DHCPv6 server address
