Cisco implementation of RIPv2 supports two modes of authentication plain text authentication and Message Digest 5 MD5 authentication. Plain text authentication mode is the default setting in every RIPv2 packet when authentication is enabled. Plain text authentication should not be used when security is an issue because the unencrypted authentication password is sent in every RIPv2 packet. Note RIP version 1 RIPv1 does not support authentication. If you are sending and receiving RIPv2 packets you can enable RIP authentication on an interface. Prerequisites Requirements Readers of this document should have the basic understanding of the following RIPv1 and RIPv2 Components Used This document is not restricted to specific software and hardware versions. Starting from Cisco IOS Software Version RIPv2 is supported and therefore all the commands given in the configuration are supported on Cisco IOS Software
