As shown in the routing table, when the default setting of load balancing is restored, the
next hops of SwitchA, that is, 10.1.1.2 (SwitchB) and 10.1.2.2 (SwitchC), become valid
routes. This is because the default number of equal-cost routes is 4.
(Optional) Set the preferences for equal-cost routes on SwitchA.
If you need not perform load balancing between SwitchB and SwitchC, set the preferences
for equal-cost routes and specify the next hop.
