LABEL DESCRIPTION
RIP & Multicast
Setup
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 RIP (Routing Information Protocol) allows a router to exchange routing information
with other routers. 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.
Multicast IGMP (Internet Group Management Protocol) is a network-layer protocol used to
establish membership in a multicast group. Multicast packets are sent to a group of
computers on the LAN and are an alternative to unicast packets (packets sent to
one computer) and broadcast packets (packets sent to every computer).
The ZyXEL Device supports both IGMP version 1 (IGMP-v1) and IGMP-v2. Select
None to disable it.
