V2-Broadcast
This field is effective when RIP is enabled. Select this to send RIP-2 packets using subnet
broadcasting; otherwise, the Zyxel Device uses multicasting.
OSPF Setting
See
for more information about OSPF.
Area
Select the area in which this interface belongs. Select
None
to disable OSPF in this interface.
Priority
Enter the priority (between 0 and 255) of this interface when the area is looking for a
Designated Router (DR) or Backup Designated Router (BDR). The highest-priority interface
identifies the DR, and the second-highest-priority interface identifies the BDR. Set the priority
to zero if the interface can not be the DR or BDR.
Link Cost
Enter the cost (between 1 and 65,535) to route packets through this interface.
Passive Interface
Select this to stop forwarding OSPF routing information from the selected interface. As a
result, this interface only receives routing information.
Authentication
Select an authentication method, or disable authentication. To exchange OSPF routing
information with peer border routers, you must use the same authentication method that
they use. Choices are:
Same-as-Area
- use the default authentication method in the area
None
- disable authentication
Text
- authenticate OSPF routing information using a plain-text password
MD5
- authenticate OSPF routing information using MD5 encryption
Text

MAC Address Setting This section appears when
Interface Properties
is
External
or
General
. Have the interface
use either the factory assigned default MAC address, a manually specified MAC address,
or clone the MAC address of another device or computer.
Use Default MAC
Address
Select this option to have the interface use the factory assigned default MAC address. By
default, the Zyxel Device uses the factory assigned MAC address to identify itself.
Overwrite
Default MAC
Address
Select this option to have the interface use a different MAC address. Either enter the MAC
address in the fields or click
Clone by host
and enter the IP address of the device or
computer whose MAC you are cloning. Once it is successfully configured, the address will
be copied to the configuration file. It will not change unless you change the setting or
upload a different configuration file.
Proxy ARP
Proxy ARP is available for external or general interfaces on the Zyxel Device. See
for more information on Proxy ARP.
Enable Proxy ARP Select this to allow the Zyxel Device to answer external interface ARP requests on behalf of
a device on its internal interface. Interfaces supported are:
• Ethernet
• VLAN
• Bridge
See
for more information.
