| NOTE: When you disable (or re-enable) Split Horizon on an interface, all EIGRP adjacencies that have been established via that interface are reset as indicated in the output above. You can verify the neighbors have reestablished successfully using the show ip eigrp neighbors command as illustrated in the following output.
