DESCRIPTION

 

 

RIP Direction

RIP (Routing Information Protocol) allows a router to exchange routing information

 

with other routers. The RIP Direction field controls the sending and receiving of

 

RIP packets.

 

Choose Both, None, In Only or Out Only.

 

When set to Both or Out Only, the Prestige will broadcast its routing table

 

periodically.

 

When set to Both or In Only, the Prestige will incorporate RIP information that it

 

receives.

 

When set to None, the Prestige will not send any RIP packets and will ignore any

 

RIP packets received.

 

By default, RIP Direction is set to Both.

 

 

RIP Version

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

 

packets that the Prestige sends (it recognizes both formats when receiving).

 

Choose RIP-1,RIP-2B or RIP-2M.

 

RIP-1is universally supported; but RIP-2carries more information. RIP-1 is

 

probably adequate for most networks, unless you have an unusual network

 

topology. Both RIP-2Band RIP-2Msends 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-V1or 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 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 such as PPPoE or PPTP, NetBIOS packets cause unwanted calls. However it may sometimes be necessary to allow NetBIOS packets to pass through to the WAN in order to find a computer on the WAN.
