T costs are calculated for cisco OSPF interfaces based upon
traditional bandwidth values associated with interface types. What's
not
clear is how the ospf process does this. Does anyone have any insight?

Thanks all for those who responded. I really appreciate for each one of
your responses
and I got a real understanding from each ones answer.
Thanks once again.

For what its worth, my studies during my CCNP prep indicated the textbook
solution was to set BW = Port Speed on the physical interface, and BW = CIR
on the subinterfaces. I also found 2600 routers with internal CSUs actually
adjust BW to equal the number of channels configured on the CSU. Setti
Setting the bandwidth would affect OSPF also. This isn't necessarily a bad
thing, though. You probably wouldn't be running both routing protocols on
the same interface, for one thing. But if you were, then you would want
them both to use a metric that's based on the actual bandwidth for the pat

I should have written more clearly.

I yield the balance of my time...

Please reference Doyle Episode 1 bottom of pg 485 and you will see how
bandwidth and costs relate.

There isn't? How d
OSPF cost is based on the bandwidth setting on Cisco routers. The cost of
an interface defaults to 100,000,000 divided by the bandwidth for the
interface. For example, a 100-Mbps Ethernet interface has a cost of 1.

Rajesh,
Correct... The bandwidth statement has no impact on other routing
protocols, like OSPF. OSPF looks at the "cost" of a link in
determining best path. There's no direct correllation between
"bandwidth" and "cost."
As for what to set "bandwidth" to, you set it on both ends of a
