Loading balancing

Equal cost load balancing, default 4 entries on IOS
Uneuqal cost load balancing support on IGRP and EIGRP with the command variance.

LB on process switching is on a per-packet basis (CPU intensive but guarantess equal load across all links)
LB on fast switching is on a per-destination basis

To set per-packet load-balancing, enable process switching (disable fast switching),
Router# config t
Router(config)# interface Ethernet 0
Router(config-if)# no ip route-cache
