11.1.7 Equal-cost multipath

When an equal-cost multipath exists from the local router to a given destination in a topology that includes more than one forwarding destination router, the OSPF protocol can balance the load to that destination by distributing packets among multiple next hops.

For internal AS routes, the Switch selects multiple paths which share the same learning source domain, destination type (inter-area or intra-area route), and cost. Similarly, for external AS routes, the switch selects multiple paths that share the same learning source domain, external AS route type, cost, and metric.

You can use the maximum-paths command to change the maximum number of paths. The default is 4.
