Figure 7 shows the links from Table 3
Point-to-point interface IP addressing
Note: The example point-to-point addresses use a 31-bit mask to prevent unnecessary sprawling of internal
addresses. This IP scheme is optional and covered in RFC 3021.
3.2.5 Interface/IP configuration
Table 4 outlines the subnets, VLANs and default gateways for the broadcast networks. Notice that the same
VLAN IDs, with different networks, repeat in each rack. The VLANs and subnets are configured on both leaf
switches and advertised through the routing instance at the same cost. ECMP spreads server traffic flow
across all uplinks.
