Configuring Cisco Express Forwarding
Selecting an Include-Ports Layer 4 Load-Balancing Algorithm for Cisco Express Forwarding Traffic
Perform the following task to select an include-ports load-balancing algorithm for Cisco Express
Forwarding traffic. Select the include-port algorithm when your network environment contains traffic
running over equal-cost paths that is not load shared because the majority of the traffic is between peer
addresses with different port numbers, such as RTP streams.
Prerequisites
Your system must be using Cisco IOS Release 15.0(1)MR or a later release.
Step 3
ip cef load-sharing algorithm {universal [id]
include-ports {source [id] | [destination] [id]
| source [id] destination [id]}}
Example:
Router(config)# ip cef load-sharing algorithm
universal 111
Selects a Cisco Express Forwarding load-balancing
algorithm.
• The universal keyword sets the load-balancing
algorithm to one that uses a source and destination and
an ID hash.
• The include-ports source keyword sets the
load-balancing algorithm to one that uses the source
port.
• The id argument is a fixed identifier.
• The include-ports destination keyword sets the
load-balancing algorithm to one that uses the
destination port.
• The include-ports source destination keyword sets
the load-balancing algorithm to one that uses the source
and destination ports.
Step 4
end
Example:
Router(config)# end
Exits to privileged EXEC mode.
Step 5
show ip cef [vrf vrf-name] exact-route
[platform] source-address destination-address
(Optional) Displays the exact route for a CEF session. You
can use the platform keyword to display the exact route for
a hardware session.
