ﬁ eld controls the format and the broadcasting method of the RIP packets that

the WR1500 Wireless Router 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 ﬁ eld is set to RIP-1.

Multicast

IGMP (Internet Group Multicast Protocol) is

a session-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

interoperability between IGMP version 2 and version 1, please see sections 4 and 5 of RFC

2236.

Windows Networking (NetBIOS over TCP/IP): NetBIOS (Network Basic Input/Output System) are TCP or UDP

broadcast packets that enable a computer to connect to and communicate with a LAN. For some dial-up services
