Cisco Express Forwarding (CEF)
This command enables load sharing for Cisco Express Forwarding (CEF). By default, CEF uses
per-destination load sharing, in which all traffic for a given destination is sent through the same interface. The
per-packet keyword changes the behavior of CEF so that packets for the same destination may be sent through different interfaces. This approach makes load sharing more effective because it increases the effective bandwidth between the router and the destination. However, packets might arrive at the destination out of order, requiring the destination host to reassemble them.
