DESCRIPTION

 

 

Private (PPPoE

This parameter determines if the ZyAIR will include the route to this remote node in

and PPTP only)

its RIP broadcasts. If select Yes, this route is kept private and not included in RIP

 

broadcast. If select No, the route to this remote node will be propagated to other

 

hosts through RIP broadcasts.

 

 

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 ZyAIR will broadcast its routing table periodically.

 

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

 

receives.

 

When set to None, the ZyAIR 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 ZyAIR 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 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 dialup services such as PPPoE or PPTP, NetBIOS packets cause unwanted calls.
