[c-nsp] Outbound Load balancing using eBGP

[Mack O'Brian]

If it is internal WAN environment, why not use PfR/OER? It comes with IOS
and has improved a lot. PfR could dynamically load balance traffic. For
Internet facing the PfR would NOT balance for full routing table but would
do upto five thousand routes or so. I maybe off on the numbers. But still
for 5k routes or so it works pretty good.
