The command ip prefix-list spine-leaf seq 10 permit 10.0.2.0/24 ge 32 includes all addresses in the 10.0.2.0/24 address range with a mask greater than or equal to 32. This includes all loopback addresses used as router IDs. The command ip prefix-list spine-leaf seq 20 permit 172.16.0.0/16 ge 24 includes the 172.16.2.0/24 network used on Leaf switches 3 and 4 as shown in Figure 17.
