5.3 Configuring DHCPv6 Relay

When the DHCPv6 client and the DHCPv6 server are on different links, you need to deploy
DHCPv6 relay agents between the DHCPv6 client and the DHCPv6 server. In this manner, the
DHCPv6 relay agents transmit DHCPv6 messages exchanged between the DHCPv6 client and
the DHCPv6 server.

5.3.1 Establishing the Configuration Task

This section describes the applicable environment, pre-configuration tasks, and data preparation
for configuring DHCPv6 relay.
Applicable Environment
When the DHCPv6 client applies to the DHCPv6 server on a different link for the IP address,
you need to deploy relay agents between the DHCPv6 client and the DHCPv6 server. In this
manner, the relay agents transmit DHCPv6 messages exchanged between the DHCPv6 client
and the DHCPv6 server.
Pre-configuration Tasks
Before configuring DHCPv6 relay, complete the following tasks:

5.3.2 Enabling the DHCPv6 Relay Function

You can enable the DHCPv6 relay function on a VLANIF interface of the S9300&S9300E, set
the IPv6 address of the DHCPv6 server or the next hop relay agent, and specify the outbound
interface of relay messages.

Data
Type and number of the interface where DHCPv6 relay is enabled (the interface type
is VLANIF)
Type and number of the interface where the function of appending the remote ID to
DHCPv6 relay messages is enabled (the interface type can be Ethernet, GE, or
XGE)
(Optional) Maximum transmission rate of DHCPv6 messages and alarm threshold of
the number of DHCPv6 messages discarded
