The output of the show ip eigrp interfaces command shows you the working interfaces on which EIGRP is enabled. Notice that Loopback 0 does not peer with any router. In other words, on the Loopback 0 interface, EIGRP packets will not be received. The same would be true for a LAN interface on which there are no additional routers attached. To preserve some resources and instruct routers to stop sending and receiving packets on the specific interface, you can configure such interfaces as passive.

The output of the show ip eigrp interfaces command shows you the working interfaces on which EIGRP is enabled. Notice that Loopback 0 does not peer with any router. In other words, on the Loopback 0 interface, EIGRP packets will not be received. The same would be true for a LAN interface on which there are no additional routers attached. To preserve some resources and instruct routers to stop sending and receiving packets on the specific interface, you can configure such interfaces as passive.
