LABEL DESCRIPTION
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 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.
RIP Version 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.
