Table 34   LAN IP Alias

IP Alias 1, 2

Select the check box to configure another LAN network for the ZyXEL Device.

IP Address

Enter the IP address of your ZyXEL Device in dotted decimal notation. 
Alternatively, click the right mouse button to copy and/or paste the IP address.

IP Subnet Mask

Your ZyXEL Device will automatically calculate the subnet mask based on the IP 

address that you assign. Unless you are implementing subnetting, use the subnet 

mask computed by the ZyXEL Device.

RIP Direction

RIP (Routing Information Protocol, RFC 1058 and RFC 1389) allows a router to 

exchange routing information with other routers. The RIP Direction field controls 

the sending and receiving of RIP packets. Select the RIP direction from Both/In 

Only/Out Only/None. When set to Both or Out Only, the ZyXEL Device will 

broadcast its routing table periodically. When set to Both or In Only, it will 

incorporate the RIP information that it receives; when set to None, it will not send 

any RIP packets and will ignore any RIP packets received.

RIP Version

This field is enabled if RIP Direction is not None. The RIP Version field controls 

the format and the broadcasting method of the RIP packets that the ZyXEL Device 

sends (it recognizes both formats when receiving). RIP-1 is universally supported 

but RIP-2 carries more information. RIP-1 is probably adequate for most 

networks, unless you have an unusual network topology. Both RIP-2B and RIP-

2M sends the routing data in RIP-2 format; the difference being that RIP-2B uses 

subnet broadcasting while RIP-2M uses multicasting. Multicasting can reduce the 

load on non-router machines since they generally do not listen to the RIP 

multicast address and so will not receive the RIP packets. However, if one router 

uses multicasting, then all routers on your network must use multicasting, also.
