In an ASA active/standby pair setup that I have, an upstream router seems to be getting ARP requests from both the active and standby ASA. Is that normal? I thought only the active unit would do all the ARP requests and ARP tables get replicated to the standby rather than the standby doing it's ARP requests. So basically I have this upstream router showing both the active and standby unit's IPs/MACs in it's ARP table.
