	Thats what I want to do as the default. However, there are other
factors influencing this. I've been having bad luck with the IPSec/GRE 
over the Satellite, so I'm leary of what might happen on my E1/0 tunnel.
I've also been graphing packet loss and reliability on the E1/0 link
and I'm not very impressed with it. Over the last 36 hours its averaged
a 25% packet loss. (And, I haven't looked into it more, but 100% packet 
loss to my end router....But I can't 100% verify it because of how I left
things configured)

	I've never used VRF. Any dummies guides out there? I did a quick
Google and find some more involved things, but looking for something starts
basic to build the foundation.
