OSPF Bandwidth Calculator
The calculator below is a simple bit of Javascript designed to show you the OSPF cost
that a Cisco router will calculate for a given bandwidth against a given reference bandwidth.
The default reference bandwidth on a Cisco router is 100 so if you haven't changed it with
the ospf auto-cost reference-bandwidth command then leave the reference bandwidth in
the calculator at the default.
The calculator may work for other vendors routers as well provided they calculate OSPF
costs in the same way.
