The relay agent is enabled when at least one configured VLAN has an entry is
listed in the IP Service > DHCPv6 > Relay (Action: Show) page.
The relay agent is disabled if there are no entries for all configured VLANs in the
IP Service > DHCPv6 > Relay (Action: Show) page.
Parameters
These parameters are displayed:
VLAN – ID of the configured VLAN.
Mode:
Unicast - To forward the client IPv6 DHCP messages to a specific
destination address(es), select the Unicast mode.
Multicast - To forward the client IPv6 DHCP messages to all available
servers on configured VLANs, select the Multicast mode. In this mode the
DHCPv6 agent forwards DHCPv6 messages to the IPv6 DHCP multicast
address known as “All_DHCP_Servers” (FF05::1:3) which both DHCPv6
servers and relay agents listen to.
Destination Address - When Unicast mode is selected, enter an IPv6 address of
a DHCPv6 server or relay agent (Maximum: 5 for each configured VLAN).
Destination VLAN – When Multicast mode is selected, select a configured
VLAN or “All” (all VLANs). The DHCPv6 messages will be forwarded on the
configured VLANs or all VLANs using the “All_DHCP_Servers” address.
