RIP metrics and the Limitations of RIP
Objectives:
To learn how about the limitations of RIP and its metrics.
Background:
In this lab we will explore 3 of the 4 “features” of RIP (version 1). First, we will test the
maximum hop count metric (15 is ok, 16 is unreachable). Next we will view the update
broadcast of RIP (every 30 seconds) and then change the timer. Finally we look at the
timers associated with RIP: route-timeout and flush timer. We will not look at the
“feature of RIP” that RIP maintains only the best routes.
Tools and Materials:
(3) PC/workstations with protocol inspectors
(3) Routers
(3) Switches
(6) Straight-through cables
(2) DCE serial cable
(2) DTE serial cable
(3) rollover cables
