DESCRIPTION
Type the IP address of your ZyWALL in dotted decimal notation 192.168.1.1
(factory default).
The subnet mask specifies the network number portion of an IP address. Your
ZyWALL 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 ZyWALL 255.255.255.0.
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
ZyWALL 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. Both
is the default.
The RIP Version field controls the format and the broadcasting method of the
RIP packets that the ZyWALL 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.
Select IGMP V-1 or IGMP V-2 or None. 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.
