[HECnet] HECnet performance....

Peter,

Everything is now set up on my end.   I now have 3 Cisco tunnels.   The metric is 10 on all of them.   The majority of areas now route through you according to my router:

You get asymetric routes. 

I will (tomorrow) get it all correct on my side, but as the uppsala
box is "central" to HECnet, you are better of forcing the traffic
there as we have no metrics/topology info from the bridged ethernet.

Then we use the stockholm/reston boxes as backup together with the
Multinet links..
