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 LAN1's IP address, the ZyWALL automatically updates the
corresponding interface-based, LAN1 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.
