The Ethernet Edit screen lets you configure IP address assignment, interface 
parameters, RIP settings, OSPF settings, DHCP settings, connectivity check, and 
MAC address settings. To access this screen, click an Edit icon in the Ethernet 
Summary screen. (See 

Note: If you create IP address objects based on an interface’s IP address, subnet, or 

gateway, the ZyWALL automatically updates every rule or setting that uses the 
object whenever the interface’s IP address settings change. For example, if you 
change LAN’s IP address, the ZyWALL automatically updates the 
corresponding interface-based, LAN subnet address object.

With RIP, you can use Ethernet interfaces to do the following things.

• Enable and disable RIP in the underlying physical port or port group.
• Select which direction(s) routing information is exchanged - The ZyWALL can 

receive routing information, send routing information, or do both.

• Select which version of RIP to support in each direction - The ZyWALL supports 

RIP-1, RIP-2, and both versions.

• Select the broadcasting method used by RIP-2 packets - The ZyWALL can use 

subnet broadcasting or multicasting.

With OSPF, you can use Ethernet interfaces to do the following things.

• Enable and disable OSPF in the underlying physical port or port group.
• Select the area to which the interface belongs.
• Override the default link cost and authentication method for the selected area.
• Select in which direction(s) routing information is exchanged - The ZyWALL can 

receive routing information, send routing information, or do both.

• Set the priority used to identify the DR or BDR if one does not exist.
