A method for link fault detection and recovery based on Address Resolution Protocol (ARP) interaction, including: configuring an IP address and a mask code, a strategy routing or static routing module and an ARP module for network devices of a home terminal and an opposite terminal; the strategy routing or static routing module regularly inquiring whether an ARP entry to which a next hop corresponds exists, if the ARP entry exists, a link being available, otherwise, notifying the ARP module to perform keepalive on the next hop; and the ARP module performing a process of keepalive on the next hop, and after performing keepalive on the next hop, notifying the strategy routing or static routing module to judge whether the link is available. Further, a device for link fault detection and recovery based on ARP interaction.
