Example for Applying the Keychain to RIP

Networking Requirements

As shown in Figure 17-8, SwitchA and SwitchB are connected using RIP-2.

The RIP connection needs to be retained during data transmission.

Configuration Roadmap

To ensure stable RIP connections, RIP protocol packets must be correctly transmitted. You are advised to authenticate and encrypt the packets to ensure transmission security. In addition, to prevent unauthorized users from forging algorithms and key strings used in authentication and encryption, you are advised to dynamically change algorithms and key strings to ensure secure RIP packet transmission. Therefore, the keychain protocol is used to ensure stability of RIP connections.

The configuration roadmap is as follows:

Configure basic RIP functions.
Configure a keychain.
Apply the keychain to RIP.

Procedure

Configure basic RIP functions.

# Configure Switch A.
