Does NAT static mapping support HSRP for high availability?
A. When an Address Resolution Protocol (ARP) query is triggered for an address that is configured with Network Address Translation (NAT) static mapping and owned by the router, NAT responds with the BIA MAC address on the interface to which the ARP is pointing. Two routers act as HSRP active and standby. Their NAT inside interfaces must be enabled and configured to belong to a group.
