All, I have seen this issue several times. What happens is sometimes the inverse-arp learns the dynamic information faster than the configuration can be applied. So the load lab scripts do a no shutdown and then apply the configuration to the interface. As soon as an IP is applied to the physical interface inverse-arp sends out information. As no inverse-arp is one of the last interface commands applied inverse-arp resolves information before the script can finish applying the initial configuration ;).
At least it says the routers are efficient at what they do. Regards, Tyson Scott - CCIE #13513 R&S, Security, and SP Technical Instructor - IPexpert, Inc.
