Hi Everyone, I could use a little help on MPLS and Traffic Engineering. Right now I'm just trying to wrap my head around it. I currently have a couple tunnels going in either direction, those are working fine (but certainly took me long enough to get them working!) and I can direct traffic over them easy enough. Now I'm looking into allocating/reserving bandwidth for a given tunnel and if possible have it react to increased network loads and recalculate its path if need be. (Poor) Example: I have two paths that two different tunnels (A and B) that will go over a T-1 and 100mbps ethernet. A is more important than B. When traffic is low, I'd like them both to go over the 100mbps link so either tunnel can fill the pipe, but if Tunnel A requires more bandwidth, Tunnel B should react and move to the T-1. Is this possible? or am I horribly confused? I'm not really looking for the exact commands or the 'answer' to this problem, but some guidance would be greatly appreciated. I'm working with Cisco gear, 2800's and such. This is purely an academic exercise. Thanks! Jeremy
