I have a wireshark here of an ASR 9010 which is setting off triggers in a monitoring system for sending a bunch of ARP requests that look like gratuitous ARPS for reasons I can't seem to determine. It is going on like this continually. I am looking for a little assistance in determining why.

hsrp would send grat arps for its vip, and it should there is a standard timer on that with some jitter to keep informing the switches of where the mac is found.
