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.
Select the format and the broadcasting method of the RIP packets that the Gateway receives.
Choices are:

•
Your selection should match the version supported by other routers on your network.
How often, in seconds, the Gateway sends routing-update messages. Default is 30 seconds.
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.
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.
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.
