[c-nsp] BGP vs PepLink / AT&T metrics on BGP

[Rogelio]

For a campus environment, I've got two WAN connections, one through 
Charter (30Mbps) and one through AT&T (50 Mbps). For load balancing, I 
am evaluating whether or not to use BGP or some sort of load sharing 
device, like PepLink.

With BGP, I am told that my AT&T pipe may get saturated quicker, as 
their metrics are better.  Anyone else have problem?  Or does anyone 
have any suggestions for someone who is new to BGP in this sort of 
situation?
