Routing Configuration WindowQuickSET Configuration Guide129AuthenticationAuthentication is a function of RIP-2 protocol only. It is not usually important to conceal theinformation in the routing messages, but it is essential to prevent the insertion of bogus routinginformation into the routers. Authentication prevents someone who cannot directly access thenetwork (i.e., someone who cannot sniff the packets to determine the password) from insertingbogus routing information. Currently the only authentication type is a simple password.MulticastingThe RIP-2 protocol provides for the IP multicasting of periodic advertisements. This feature wasadded to RIP-2 to decrease the load on systems that do not support RIP-2. It also provides amechanism whereby RIP-1 routers will never receive RIP-2 routes. This feature is useful when thecorrect use of an advertised route depends on knowing the precise subnet mask, which would beignored by a RIP-1 router.Compatibility SwitchA compatibility switch is necessary for two reasons. First, there are implementations of RIP-1 inthe field that do not follow RFC1058, and second, the use of multicasting would prevent RIP-1systems from receiving RIP-2 updates (which may be a desired feature in some cases). This switchis configurable on a “per-interface” basis.The switch has four send settings (or choices):• RIP-1- in which only RIP-1 messages are sent (and received).• RIP-1 Compatible - in which RIP-2 messages are broadcast *• RIP-2- in which RIP-2 messages are multicast• None - which disables the sending of all RIP messages* RIP-1 Compatible mode should only be used when all of the consequences of its use are wellunderstood by the network administrator.The Receive ControlThis control is also configurable on a “per-interface” basis, and has four settings (or choices):• To accept RIP-1 messages only• To accept RIP-2 messages only• To accept both RIP-1 and RIP-2 messages *• and None; to not accept any type of RIP messages
