6.6 Upstream interface configuration
Each upstream (spine-connected) interface is configured as follows:
1. Provide an interface description.
2. Put each interface into Layer 3 mode by running the no switchport command and assigning an IP
address per Table 1.
3. Set the MTU to 9216 bytes to allow jumbo frames.
Upstream interfaces

no shutdown
Note: The remaining leaf switches are configured in the same manner. S4148U-ON leaf switches use
different ports, ethernet 1/1/25-1/1/26, for the 100GbE connections to the spines.
6.7 Route map configuration
In this section, a route map is configured to redistribute all loopback addresses used as router IDs and VTEP
addresses via BGP.
1. Configure a route map named spine-leaf.
2. Set the route map to match the IP prefix list items named spine-leaf.
3. Configure two IP prefix list items:
a. The prefix list that specifies 10.2.2.0/24 ge 32 includes all addresses in the 10.2.2.0/24
address range with a mask greater than or equal to 32. This range includes all leaf router IDs.
b. The prefix list that specifies 10.222.222.0/24 ge 32 includes all addresses in the
10.222.222.0/24 address range with a mask greater than or equal to 32. This range includes all
VTEP IP addresses.
