Loopback addressing
All loopback addresses used are part of the 10.0.0.0/8 address space with each address using a 32-bit mask.
In this example, the third octet represents the layer, “1” for the spine and “2” for the leaf. The fourth octet is
the counter for the appropriate layer. For example, 10.0.1.1/32 is the first spine switch in the topology while
10.0.2.4/32 is the fourth leaf switch.
5.3 Point-to-point interfaces
Table 3 lists layer 3 connection details for each leaf and spine switch.
All addresses come from the same base IP prefix, 192.168.0.0/16 with the third octet representing the spine
number. For example, 192.168.1.0/31 is a two-host subnet connected to Spine 1 while 192.168.2.0/31 is
connected to Spine 2. This IP scheme is easily extended as leaf and spine switches are added to the
network.
Link labels are provided in the table for quick reference with Figure 16.
