A collaboration Engineer using the SHOW EIGRP service-family External-client IOS Command, noticed that a CUCM failed to register as an external SAF Client on a Cisco IOS router named SiteC-CRTR.

The engineer has collected snippets of the IOS configuration screenshots and CUCM trace shown in the exhibit.
