Robert and Siva, > It only makes sens if you are doing 100% of traffic engineering in your IP core and limited multicast. But if one of your LSPs is down, some traffic will take the shortest path. Hence it is not 100% of TE anymore. So even if you are reserving bandwith, you cannot guarantee that bandwith will be available all time.
