Claim:
1. A control channel establishing method, wherein the method is applicable to a virtual cluster system, wherein the virtual cluster system comprises a first forwarding point (FP), a second FP, and a controller, and wherein a first Link Layer Discovery Protocol (LLDP) neighbor relationship is established between the first FP and the second FP, the method comprising: sending, by the first FP, topology information of the first FP to the second FP by using the first LLDP neighbor relationship, wherein the second FP sends, after receiving the topology information of the first FP, the topology information of the first FP to the controller through a first control channel, wherein the first control channel is pre-established between the second FP and the controller; receiving, by the first FP, first routing information that is sent by the controller and is used by the first FP to reach the controller, wherein the first routing information is generated by the controller according to the topology information of the first FP; and establishing, by the first FP, a second control channel with the controller according to the first routing information.
