This mechanism enables the binding table to recover in the event of a device reboot. The recovery mechanism
will block any data traffic sourced from an unknown source; that is, a source not already specified in the
binding table and previously learned through ND or DHCPgleaning. Thisfeature recoversthe missing binding
table entries when the resolution for a destination address fails in the destination guard. When a failure occurs,
a binding table entry is recovered by querying the DHCP server or the destination host, depending on the
configuration.
