Configure a route map and IP prefix-list to redistribute all loopback addresses and leaf networks via BGP.
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 13.

Configure UFD. This shuts the downstream interfaces if all uplinks fail. The hosts attached to the switch use
the remaining LACP LAG member to continue sending traffic across the fabric. Finally, exit configuration
mode and save the configuration.
