The output shows two valid routes to destination 9.1.1.0/24: the route with next hop 3.1.1.1 is
marked with a greater-than sign (>), indicating it is the best route (because the ID of Switch B
is smaller); the route with next hop 3.1.2.1 is marked with only an asterisk (*), indicating it is a
valid route, but not the best.
By using the display ip routing-table command, you can find only one route to 9.1.1.0/24 with
next hop 3.1.1.1 and outbound interface VLAN-interface 200.
On Switch A, configure the number of ECMP routes destined for AS 65009 to improve link
