Embodiment 1
[0070] This embodiment provides a method for sending traffic diversion routing information, which is applied to a cleaning device in an MPLS VPN network. The MPLS VPN also includes at least two CE routers, and the cleaning device and each CE router have an EBGP neighbor relationship.
[0071] Such as image 3 As shown, the method includes:
[0072] Step S101: The cleaning device generates drainage routing information, which carries the AS (Autonomous System, autonomous system) number and the IP address of the protected node. The AS number is the AS of the first CE router connected to the network segment to which the protected node belongs. No;
[0073] Step S102: The cleaning device sends the traffic routing information to the first CE router and the second CE router, so that the first CE router discards the traffic routing information according to the AS number and the EBGP loop prevention mechanism, and makes the second CE router discard the traffic routing information acco...
Embodiment 2
[0135] Based on the same inventive concept, this embodiment provides a cleaning device, which is applied in MPLS VPN (Multi-Protocol Label Switching Virtual Private Network, multi-protocol label switching virtual private network), and MPLS VPN also includes at least two customer edge CE routers , the cleaning device has an external Border Gateway Protocol EBGP neighbor relationship with each CE router. Such as Figure 5 As shown, the cleaning equipment includes:
[0136] The generating unit 301 is configured to generate traffic routing information, where the routing routing information carries the AS number of the autonomous system and the IP address of the protected node, where the AS number is the AS number of the first CE router connected to the network segment to which the protected node belongs;
[0137] The sending unit 302 is configured to receive the diversion route information from the generation unit 301, and send the diversion route information to the first CE rout...
Embodiment 3
[0150] Based on the same inventive concept, the present embodiment provides a cleaning device, which is applied in MPLS VPN (Multi-Protocol Label Switching Virtual Private Network, multi-protocol label switching virtual private network), MPLS VPN also includes at least two customer edge CE routers, The cleaning device has an external Border Gateway Protocol (EBGP) neighbor relationship with each CE router. Such as Image 6 As shown, the cleaning equipment includes:
[0151] Memory 410, for storing program codes;
[0152] The processor 420 is configured to read the program code from the memory to execute: generate drainage routing information, the drainage routing information carries the AS number of the autonomous system and the IP address of the protected node, and the AS number is the network segment connection to which the protected node belongs The AS number of the first CE router;
[0153] The network interface 430 is configured to send the diversion routing informatio...
