Description (partial)

Symptoms: A router that is configured with Hot Standby Router Protocol (HSRP) 
may respond with the incorrect MAC address to an Address Resolution Protocol 
(ARP) request for an HSRP virtual IP address.

Conditions: This symptom is observed on a Cisco router if local proxy ARP is 
enabled and the virtual IP address in not active, or the HSRP group is not 
configured locally. This caveat prevents the nonactive router from giving an 
incorrect response.
