A DHCPv6 relay agent enables the DHCPv6 client and server on different links to exchange DHCPv6 messages. The DHCPv6 relay agent forwards DHCP messages to the destination DHCPv6 server on a different network segment. DHCPv6 clients on multiple networks can share one DHCPv6 server.
Before configuring a DHCPv6 relay agent, complete the following tasks:
Configure the peer DHCPv6 server or DHCPv6 PD server.
Configure a route from the switch to the DHCPv6 server or DHCPv6 PD server.
