The guaranteed bw feature of TE LSPs could be useful for supporting
customers who are willing pay for it. Shunting VPNs into TE LSPs with
guaranteed bw helps ensure that this bw constraint can be met for the VPN
customer.
The other philosophy that you brought up is to use COS with the EXP
bits. Is there IOS support for classifying traffic into different queues
(say WFQ) based on the MPLS EXP bits?
thanks,
Ravi
