1. How do i get to see the total bandwidth utilization on my Cisco
1721 router?
2. Am setting up a Test bed for QOS. I have configured 3 linux boxes
to be routers. These form a triangular bed. If i use the switch for
connectivity between the three routers, will it cause problems?
Basically, the routing tables will take care of the routing and switch
is being used to reduce the wiring. Will this cause problems? Is a
VLAN solution prefered instead of using a switch? What if we hard wire
the boxes for connectivity?

Thanks in advance
