For RIP v2, in the Authentication for RIP v2 section, check or uncheck the Enable
box to enable or disable authentication. This section of the page is available only if
you chose In, Out, or Both for the RIP Direction and either RIP-2B or RIP-2M for the
RIP Version.
RIP v2 authentication forces authentication of RIP packets before routes are
exchanged with other routers. It acts as a security feature because routes are
exchanged only with trusted routers in the network. RIP authentication is disabled
by default. You can enter two key parameters so that routes can be exchanged
with multiple routers and RV220Ws present in the network. The second key also
acts as a failsafe when authorization with first key fails.
If you enabled RIP v2 authentication, enter the following first and second key
parameters, as described below. This section of the page is available only if you
enabled RIP v2 Authentication.
• MD5 Key ID—Input the unique MD-5 key ID used to create the
Authentication Data for this RIP v2 message.
• MD5 Authentication Key—Input the authentication key for this MD5 key.
The authentication key is encrypted and sent along with the RIP-V2
message.
• Not Valid Before—Enter the start date and time when the authentication key
is valid for authentication.
• Not Valid After—Enter the end date and time when the authentication key is
valid for authentication.
