Eigrp Load Balancing

According to the info below if I disable fast switching then I'll have per-packet load balancing and if I have fast switching enable then I have per-destination load balancing right?

Per-destination or per-packet load-balancing depends on the type of switching scheme used for IP packets.

By default, on most Cisco routers, fast switching is enabled under interfaces. This is a demand caching

scheme that does per-destination load-balancing. To set per-packet load-balancing, enable process

switching (or disable fast switching),

According to http://www.cisco.com/en/US/tech/tk365/technologies_tech_note09186a0080094820.shtml#topic1, that's correct, unless you're using CEF which is configured differently. See http://www.cisco.com/en/US/docs/ios/12_0/switch/configuration/guide/xccefc.html.

Take note of the cautions of doing per packet.
