Configuring IP
6 - 57
As shown in Table 6.7, the results of the network-based IP load sharing algorithm provide evenly-distributed load
sharing. Figure 6.8 shows a network where a routing switch has eight equal-cost paths to destination networks
N1 – N8. The routing switch (R1) has been enabled to support up to eight IP load sharing paths.
Figure 6.8 Network-based IP load sharing – example with eight equal-cost paths and eight destination networks
As shown in this example, the algorithm for network-based IP load-sharing does not select the paths beginning
with the first path, but the algorithm nonetheless results in an evenly distributed selection of paths.
Disabling or Re-Enabling Load Sharing
If you do not use IP load sharing and you want to disable the feature, use either of the following methods.
USING THE CLI
To disable IP load sharing, enter the following commands:
HP9300(config)# no ip load-sharing
Syntax: [no] ip load-sharing

R1 is configured with eight
IP load sharing paths, and has
eight paths to networks N1 - N8,
attached to R10.
The cache entries in this example
are based on the assumption that
R1 receives traffic for N1 - N8, in
that order.
