Figure 8.1 – Basic spine/leaf diagram

Let’s assume that we have what’s shown in the preceding diagram and we need data to be configured on the switches for downstream servers to run an application:

  • Switch 01:
    • Loopback IP: 192.168.0.1
    • Loopback mask: /32
    • Interface GigabitEthernet 1/0/1 IP: 192.168.10.1
    • Interface GigabitEthernet 1/0/1 mask: /24
  • Switch 02:
    • Loopback IP: 192.168...
