METHOD FOR UPDATING ROUTING IN NETWORK, NETWORK DEVICE AND SYSTEM

Document Type and Number:

WIPO Patent Application WO/2018/141215

Kind Code:

A1

Abstract:

Provided in the present application are a method for updating routing in a network, a network device, and a system. A first network device establishes a correspondence between an IP network segment and a first IP address, the first IP address being the IP address of the first network device. The first network device sends a first LSA packet to a third network device, such that the third network device generates a first route wherein a target address is a second IP address, the next hop IP address of the first route being the IP address of the first network device, and the second IP address belonging to the IP network segment. When determining that the next hop of the route in the third network device having the first IP address as a next hop and having a target address belonging to said IP network segment needs to be switched, the first network device sends a second LSA packet to the third network device and, by means of sending an LSA packet, causes the third network device to switch the next hop of the route belonging to the IP network segment from the first network device to the second network device, thereby increasing the routing update speed.
