Re: BGP load balancing using Loopbacks.

Equal-cost load-sharing does not require any special configuration.
Unequal load sharing does and it doesn't happen automatically. While
yes, the limit for unequal-cost load sharing may be 16, for equal-cost
it's 6 by default (even though this may be platform and IOS
dependent). It can be changed with "maximum-paths" under EIGRP
process.
