CDRouter 6.2 and later support the MD5 Authentication Mode for RIPv2. The testvar ripSimplePassword has been deprecated. While it is still supported for legacy configurations, it is replaced by the new testvar ripPassword, which is used in conjunction with another new testvar, ripAuthMode. There are three configurations possible between these two testvars:
No Authentication
testvar ripAuthMode none
Plaintext Authentication
testvar ripAuthMode simple testvar ripPassword secret-password
MD5 Authentication
testvar ripAuthMode md5 testvar ripPassword secret-password
