Lab 38:
Passive Interfaces for RIPv2 Updates
Lab Objective:
The objective of this lab exercise is for you to learn and understand how to prevent RIPv2 from sending unnecessary updates by using passive interfaces.
Lab Purpose:
Preventing unnecessary RIPv2 updates using passive interfaces is a fundamental skill. By default, RIPv2 sends updates via Multicast on all interfaces for which RIPv2 has been enabled. For example, it is not possible to ever have another device connected to a Loopback interface, so it is a waste of router processing power to have RIPv2 continuously send updates to a Loopback interface.
