6.6.3 Setting the Maximum Number of Equal-Cost Routes

If the destinations and costs of the multiple routes discovered by one routing protocol are the
same, load balancing can be performed among these routes.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
ospfv3 [ process-id ]
The OSPFv3 view is displayed.
Step 3 Run:
maximum load-balancing number
The maximum number of equal-cost routes is set.
When the number of equal-cost routes is greater than number specified in the maximum load-
balancing command, valid routes are selected for load balancing based on the following criteria:

1.

2.
3.
Step 4 (Optional) Run:
nexthop ip-address weight value
The route preferences are configured for load balancing.
To specify valid routes for load balancing, run the nexthop command to set the route preference.
Ensure that the preferences of valid routes to be used must be high.
The smaller the weight value, the higher the preference of the route. The default weight value
is 255, which indicates that load balancing is implemented regardless of the route preferences.

Route preference: Routes with lower preferences are selected for load balancing. For details
about route preference configuration, see
Interface index: If routes have the same priorities, routes with higher interface index values
are selected for load balancing.
Next hop IP address: If routes have the same priorities and interface index values, routes
with larger IP address are selected for load balancing.
