Method and apparatus for determining next hop and advertising routing information

Abstract

Embodiments of the present application disclose a method and an apparatus for determining a next hop and advertising routing information, which relate to the field of communications and are used for reducing operation complexity of a forwarding device and reducing network maintenance workload. The method for determining the next hop provided by the embodiments of the present application includes: receiving, by a control device, first routing information sent by a first forwarding device, where the first routing information includes an identifier of the first forwarding device; determining a first routing path according to the identifier of the first forwarding device, an identifier of a second forwarding device and a routing path group; and determining a next hop in second routing information for the second forwarding device according to the first routing path, where the second forwarding device is a receiver of the second routing information advertised by the control device.

What is claimed is: 
     
         1 . A method for determining a next hop, comprising:
 receiving, by a control device, first routing information sent by a first forwarding device, wherein the first routing information comprises an identifier of the first forwarding device;   determining a first routing path according to the identifier of the first forwarding device, an identifier of a second forwarding device and a routing path group; and   determining a next hop in second routing information for the second forwarding device according to the first routing path, wherein the second forwarding device is a receiver of the second routing information advertised by the control device.
