LABEL DESCRIPTION
Metric This option appears when Interface Type is external or general. Enter the priority of the
gateway (if any) on this interface. The Zyxel Device decides which gateway to use based
on this priority. The lower the number, the higher the priority. If two or more gateways have
the same priority, the Zyxel Device uses the one that was configured first.
Enable IGMP Support Select this to allow the Zyxel Device to act as an IGMP proxy for hosts connected on the
IGMP downstream interface.
IGMP Upstream Enable IGMP Upstream on the interface which connects to a router running IGMP that is
closer to the multicast server.
IGMP Enable IGMP Downstream on the interface which connects to the multicast hosts.
Downstream
IPv6 Address These IP address fields configure an IPv6 IP address on the interface itself.
Assignment

(SLAAC)
Link-Local This displays the IPv6 link-local address and the network prefix that the Zyxel Device
address
generates itself for the interface.
IPv6 Address/ Enter the IPv6 address and the prefix length for this interface if you want to use a static IP
Prefix Length
address. This field is optional.
The prefix length indicates what the left-most part of the IP address is the same for all
computers in the network, that is, the network address.
Gateway Enter the IPv6 address of the default outgoing gateway using colon (:) hexadecimal
notation.
Metric Enter the priority of the gateway (if any) on this interface. The Zyxel Device decides which
gateway to use based on this priority. The lower the number, the higher the priority. If two or
more gateways have the same priority, the Zyxel Device uses the one that was configured
first.
Address from Use this table to have the Zyxel Device obtain an IPv6 prefix from the ISP or a connected

Delegated Select the DHCPv6 request object to use from the drop-down list.
Prefix
Suffix Enter the ending part of the IPv6 address, a slash (/), and the prefix length. The Zyxel Device
Address
will append it to the delegated prefix.
For example, you got a delegated prefix of 2003:1234:5678/48. You want to configure an IP
address of 2003:1234:5678:1111::1/128 for this interface, then enter ::1111:0:0:0:1/128 in this
field.
Chapter 10 Interfaces
Prefix Delegation on page 300
Create at least one DHCPv6 request object before configuring this table.
The external interface must be a DHCPv6 client. You must configure the DHCPv6
request options using a DHCPv6 request object with the type of prefix-delegation.
Assign the prefix delegation to an internal interface and enable router advertisement
on that interface.
