https://www.cisco.com/c/en/us/td/docs/switches/datacenter/sw/nx-os/lisp/configuration/guide/b_NX-OS_LISP_Configuration_Guide/b_NX-LISP VM (Virtual Machine) mobility is a feature that allows virtual machines to maintain their IP address and network connection when they are moved from one physical host to another within a data center network.
When LISP VM mobility is enabled on an interface, it uses the Locator/ID Separation Protocol (LISP) to decouple the virtual machine's identity (ID) from its location (locator). This allows the virtual machine to maintain its IP address and network connectivity even if it is moved to a different subnet or data center location.
Out of the answer options provided, the feature that is typically configured on interfaces that have LISP VM mobility enabled is proxy ARP (Answer C).
Proxy ARP is a technique used by a network device to respond to ARP (Address Resolution Protocol) requests on behalf of another device. When a virtual machine with a specific IP address is moved to a new physical host, it will send ARP requests to determine the MAC address of the default gateway. If the virtual machine's IP address is still associated with its old physical location, the ARP request will not reach the default gateway, resulting in a loss of network connectivity.
To prevent this, the network device (such as a router or switch) can be configured with proxy ARP, which will respond to the virtual machine's ARP request with the MAC address of the default gateway. This allows the virtual machine to maintain its network connectivity even if it has been moved to a new physical location.
IP redirects (Answer A) are used by routers to inform hosts that a better path exists for a particular destination, but they are not directly related to LISP VM mobility. Flow control (Answer B) is a mechanism for regulating the rate of data transmission between network devices and is not related to LISP VM mobility or ARP. HSRP (Answer D) is a redundancy protocol that provides automatic failover in case of a primary device failure, but it is not specifically related to LISP VM mobility or ARP.
