22 Dell EMC Networking Layer 3 Leaf-Spine Deployment and Best Practices with OS10 | Version 1.0
Internal Use - Confidential
Configure a route map and IP prefix-list to redistribute all loopback addresses and leaf networks via BGP or
OSPF.
The command seq 10 permit 10.0.0.0/8 ge 24 includes all addresses in the 10.0.0.0/8 address
range with a mask greater than or equal to 24. This includes all loopback addresses used as router IDs as
well as the 10.60.1.0/24 network used on leaf switches 3 and 4 as shown in Figure 12.
The command seq 20 permit 172.16.0.0/16 ge 24 includes the 172.16.1.0/24 network used on leaf
switches 1 and 2 as shown in Figure 12.

Enable OSPF globally and redistribute connected networks according to the previously defined route map.
Finally, exit configuration mode and save the configuration.
