SMCD3GN2 Wireless Cable Modem Gateway Administrator Manual

Table 14. RIP Control Menu Options

Option Description

WPS Summary

Interface Name Select the name of the interface. Choices are

• Cable (default)

• CPE

RIP Send Version Select the format and the broadcasting method of the RIP packets that the Gateway sends. Choices

are:

• Do Not Send (default)

• RIP1

• RIP2

• RIP1/2

Your selection should match the version supported by other routers on your network.

RIP Receive Version Select the format and the broadcasting method of the RIP packets that the Gateway receives.

Choices are:

• Do Not Receive (default)

• RIP1

• RIP2

• RIP1/2

Your selection should match the version supported by other routers on your network.

Update Interval How often, in seconds, the Gateway sends routing-update messages. Default is 30 seconds.

Default Metric Number by which the metric value for the path increases when the Gateway receives a routing

update that includes changes to an entry. Choices are 1 – 15. Default is 1.

Authentication Type The authentication mechanism used, if any. Choices are:

• No Authentication = no authentication is used. If you keep this default setting, the Authentication

Key & ID fields are gray and unavailable. (default)

• Simple Password = an authentication method where a clear text password is sent to participating

neighbors on the network. This selection sends the authenticating password over the network,

possible making it available to individuals who can access packets off the network. Do not use this

option as part of your security strategy, Rather, use it to avoid accidental changes to the routing

infrastructure. If you select this setting, the first field in the Authentication Key & ID option becomes

available for entering the password.

• MD5 = an authentication method that works much like Simple Password authentication, except

that MD5 does not send the key over the network. Instead, a router uses the MD5 algorithm to

produce a message digest of the key (also called a hash). The router sends the message digest

instead of the key itself, which ensures that no one can eavesdrop on the network and learn keys

during transmission. If you select this setting, the first field in the Authentication Key & ID option

becomes available for entering the key and the second field becomes available for entering the ID.

Authentication Key & ID Specify the appropriate information based on the Authentication Type selected:

• No Authentication – no entry required; fields are gray and unavailable. (default)

• Simple Password = in the first field, enter the clear-text password to be used for authentication.

The second field requires no entry, and is gray and unavailable.

• MD5 = in the first field, enter the MD5-hash password. In the second field, enter the Key Identifier

that identifies the key used to create the authentication data for this message.
