LABEL DESCRIPTION
# This field is a sequential value, and it is not associated with any entry.
IPv6 Enter the IPv6 network prefix address and the prefix length.
Address/
Prefix Length
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.
Advertised Prefix Use this table to configure the network prefix if you want to use a delegated prefix as the
from DHCPv6
beginning part of the network prefix.

# This field is a sequential value, and it is not associated with any entry.
Delegated Select the DHCPv6 request object to use for generating the network prefix for the network.
Prefix
Suffix Enter the ending part of the IPv6 network address plus a slash (/) and the prefix length. The
Address
Zyxel Device will append it to the selected delegated prefix. The combined address is the
network prefix for the network.
For example, you got a delegated prefix of 2003:1234:5678/48. You want to divide it into
2003:1234:5678:1111/64 for this interface and 2003:1234:5678:2222/64 for another interface.
You can use ::1111/64 and ::2222/64 for the suffix address respectively. But if you do not
want to divide the delegated prefix into subnetworks, enter ::0/48 here, which keeps the
same prefix length (/48) as the delegated prefix.
Address This is the final network prefix combined by the delegated prefix and the suffix.
Note: This field displays the combined address after you click OK and reopen this
Interface Parameters
Egress Bandwidth Enter the maximum amount of traffic, in kilobits per second, the Zyxel Device can send
through the interface to the network. Allowed values are 0 - 1048576.
Ingress This is reserved for future use.
Bandwidth
Enter the maximum amount of traffic, in kilobits per second, the Zyxel Device can receive
from the network through the interface. Allowed values are 0 - 1048576.
MTU Maximum Transmission Unit. Type the maximum size of each data packet, in bytes, that can
move through this interface. If a larger packet arrives, the Zyxel Device divides it into smaller
fragments. Allowed values are 576 - 1500. Usually, this value is 1500.
Connectivity Check The Zyxel Device can regularly check the connection to the gateway you specified to
make sure it is still available. You specify how often to check the connection, how long to
wait for a response before the attempt is a failure, and how many consecutive failures are
required before the Zyxel Device stops routing to the gateway. The Zyxel Device resumes
routing to the gateway the first time the gateway passes the connectivity check.
Enable Select this to turn on the connection check.
Connectivity
Check
Check Method Select the method that the gateway allows.
Select icmp to have the Zyxel Device regularly ping the gateway you specify to make sure
it is still available.
Select tcp to have the Zyxel Device regularly perform a TCP handshake with the gateway
you specify to make sure it is still available.
