RIP v2 authentication forces authentication of RIP packets before routes are
exchanged with other routers and RV220Ws. It acts as a security feature because
routes are exchanged only with trusted routers and RV220Ws 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.
To enable authentication for RIP-2B or RIP-2M, check the Enable box. (You must
also choose the direction as explained in Step 1.)
If you enabled RIP v2 authentication, enter the following first and second key
parameters:
• 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.
Click Save.
