A route synchronization method, comprising: receiving, by a first Fiber Channel over Ethernet, FCoE, edge forwarder, FEF, an entire network address request message sent by a second FEF, wherein the entire network address request message comprises a media access control, MAC, address and a fiber channel, FC, network segment of the second FEF; parsing, by the first FEF, the entire network address request message, acquiring the MAC address and the FC network segment of the second FEF, and storing the MAC address and the FC network segment of the second FEF in a routing table of the first FEF, wherein the routing table of the first FEF includes a mapping relationship between the FC network segment of the second FEF and the MAC address of the second FEF to implement normal data transmission; and returning, by the first FEF, a response message to the second FEF, wherein the response message comprises a MAC address and an FC network segment of the first FEF; sending, by the first FEF, a destination address request message, wherein the destination address request message comprises an FC address of a target device and the MAC address and the FC network segment of the first FEF; receiving, by the first FEF, a destination address request response message returned by a fourth FEF communicated with the target device by using FCoE technology, wherein the destination address request response message comprises a MAC address and an FC network segment of the fourth FEF; and parsing, by the first FEF, the destination address request response message, acquiring the MAC address and the FC network segment of the fourth FEF, and storing the MAC address and the FC network segment of the fourth FEF in the routing table of the first FEF. receiving, by a first Fiber Channel over Ethernet, FCoE, edge forwarder, FEF, an entire network address request message sent by a second FEF, wherein the entire network address request message comprises a media access control, MAC, address and a fiber channel, FC, network segment of the second FEF; parsing, by the first FEF, the entire network address request message, acquiring the MAC address and the FC network segment of the second FEF, and storing the MAC address and the FC network segment of the second FEF in a routing table of the first FEF, wherein the routing table of the first FEF includes a mapping relationship between the FC network segment of the second FEF and the MAC address of the second FEF to implement normal data transmission; and returning, by the first FEF, a response message to the second FEF, wherein the response message comprises a MAC address and an FC network segment of the first FEF; sending, by the first FEF, a destination address request message, wherein the destination address request message comprises an FC address of a target device and the MAC address and the FC network segment of the first FEF; receiving, by the first FEF, a destination address request response message returned by a fourth FEF communicated with the target device by using FCoE technology, wherein the destination address request response message comprises a MAC address and an FC network segment of the fourth FEF; and parsing, by the first FEF, the destination address request response message, acquiring the MAC address and the FC network segment of the fourth FEF, and storing the MAC address and the FC network segment of the fourth FEF in the routing table of the first FEF.
