The following table describes the fields in this screen
LABEL
IP Alias 1,2
Select the check box to configure another LAN network for the ZyXEL device.
IP Address
Enter the IP address of the ZyXEL device in dotted decimal notation.
IP Subnet Mask
The ZyXEL device automatically calculates the subnet mask based how many aliases
you select. See also the appendices for more information on IP subnetting.
RIP Direction
RIP (Routing Information Protocol, RFC1058 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 broadcasts its routing
table periodically. When set to Both or In Only, it incorporates the RIP information that
it receives; when set to None, it does not send any RIP packets and ignores any RIP
packets received.
The RIP Version field controls the format and the broadcasting method of the RIP
RIP Version
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. By default,
RIP direction is set to Both and the Version set to RIP-1.
