Abstract

The embodiment of the invention provides route equipment, a route reflector, a route information processing method and a route information processing system. The route information processing method comprises the following steps that: first route equipment receives the route information of second route equipment and disconnection no deletion identification information corresponding to the route information from the route reflector; the first route equipment determines that border gateway protocol (BGP) connection between the first route equipment and the route reflector is passively disconnected; and the first route equipment processes the route information corresponding to the disconnection no deletion identification information in a graceful restart (GR) mode. In the embodiment of the invention, the route information of other route equipment, which is positioned on a forwarding path, is processed in the GR mode, so that the forwarding path among the equipment is kept unchanged temporarily, the smoothness of service flow is ensured, and flow loss is avoided.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a routing device, a routing reflector, and a routing information processing method and system. Background technique [0002] As more and more routing devices are connected to the network, the full mesh connection of the network becomes more and more complex. Route Reflector (RR) can be used to simplify the internal border gateway protocol (Internal Border Gateway Protocol, referred to as : Full mesh connection of IBGP). [0003] figure 1 It is a network diagram of a single reflector of a virtual private network (Virtual Private Network, referred to as VPN) in the prior art, such as figure 1 As shown, the VPN network includes RR, service provider edge (Provider Edge, referred to as: PE) equipment PE1, PE2 and user edge (Customer Edge, referred to as: CE) equipment CE1, CE2, and CE is the client that the user connects to PE At the same time, PE1 and PE2 als...
