The second command lists more detailed information about specific interfaces, including the localrouter's own Hello interval and hold time, and horizontal split settings.Note that neither command lists information about interfaces that are not EIGRP-enabled. For example, if EIGRP is not enabled on S0/0/0, show ip eigrp interfaces detail S0/0/0 does not list any information under the header line. the short output of the show ip eigrp interface command omits interfaces that are not EIGRP-enabled.Also note that the show ip eigrpinterfaces... command does not list information about passive interfaces. Similar to open shortest path first (OSPF, Open Shortest PathFirst), EIGRP supports the passive-interface type number subcommand. This command tells EIGRP not to discover and form neighbor relationships on the listed interfaces. However, EIGRP still advertises the subnet to which the interface is connected.206 Chapter 10 Implementing IPv4 EIGRP In summary, the show ip eigrp interfaces command lists information about the interfaces enabled by EIGRP, but it does not list the EIGRP
