Configuring Cisco Express Forwarding
Cisco Express Forwarding load balancing is based on a combination of source and destination packet
information; it allows you to optimize resources by distributing traffic over multiple paths.
You can configure load balancing on a per-destination or per-packet basis. Because load-balancing
decisions are made on the outbound interface, load balancing must be configured on the outbound
interface.
Note The Cisco MWR 2941 does not currently support per-packet load balancing.
The following sections describe how to configure Cisco Express Forwarding.
