Vantage CNM User’s Guide

Since ZyWALL 4.00, the WAN screens are organized differently than the previous versions 
because it has two WAN ports. Use the WAN1 and WAN2 tabs to configure the WAN1 and 
WAN2 ports. These tabs are similar and vary by encapsulation type.

Use this screen to configure an Ethernet connection on one of the device’s WAN ports. To 
open this screen, click Device Operation > Device Configuration > Network > WAN > 
WAN1/2.

RIP Version

The RIP Version field controls the format and the broadcasting method of the 

RIP packets that the device sends (it recognizes both formats when 

receiving). 
Choose RIP-1, RIP-2B or RIP-2M.
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, the RIP 

Version field is set to RIP-1.

Multicast

Choose None (default), IGMP-V1 or IGMP-V2. IGMP (Internet Group 

Multicast Protocol) is a network-layer protocol used to establish membership 

in a Multicast group - it is not used to carry user data. IGMP version 2 (RFC 

2236) is an improvement over version 1 (RFC 1112) but IGMP version 1 is 

still in wide use. If you would like to read more detailed information about inter 

operability between IGMP version 2 and version 1, please see sections 4 and 

5 of RFC 2236.
