Enabling Authentication for RIP Exchanges (Optional)

All RIPv2 protocol exchanges can be authenticated to guarantee that only trusted routers participate in the AS's routing. By default, this authentication is disabled. Authentication requires all routers within the RIP network or subnetwork to have the same authentication type and key (password) configured.

You can enable RIP authentication exchanges by either of the following methods:

• Enabling Authentication with Plain-Text Passwords
• Enabling Authentication with MD5 Authentication
