IP maintains multiple equal-cost OSPF routes. Load sharing enables a router
to divide traffic over equal-cost routes. The router can have several next hops
available toward any destination. With this configuration, the router can
divide the traffic among the various equal-cost routes to the destination. As a
result, load sharing increases the effective bandwidth of an end-to-end path. In
addition, it can improve the traffic distribution on an internetwork.
NOTE:
Load sharing is performed only on equal-cost routes learned from OSPF.
You enable load sharing within OSPF. IP maintains a maximum of four equal-
cost routes to each destination network. The OSPF equal-cost routes are
maintained internally and are not displayed in TCPCON.
IMPORTANT:
Because OSPF networks tend to be large and complex, we
recommend that you do not manually adjust the cost of the interface to create
equal-cost routes. It is best to let OSPF automatically determine the equal-cost
routes to the destination network.
To configure load sharing on the router do the following:
1
Load INETCFG, and then select Protocols > TCP/IP.
2
Select OSPF > Enabled.
3
Select OSPF Configuration.
4
Select IP Load Sharing > Enabled.
