Problems solved by technology

Based on this, when the GR of the OSPF routing protocol is run on the MDC of a physical network device, the MDC directly connected to the MDC is not necessarily an independent physical network device, but may also be an MDC virtualized from the same physical network device, and The two MDCs have the same main control board. Therefore, when the main control board of a physical network device fails, all MDCs in the physical network device undergo active / standby switchover at the same time, and GR processing will fail at this time.

Embodiment Construction

[0052] Aiming at the problems existing in the prior art, the embodiment of the present invention provides a routing process management method based on a virtual network device, which is applied to a physical network device virtualized into multiple MDCs (logical network devices), and is used to manage the routing process ( such as the GR process of the OSPF protocol) for management; figure 1 It is a schematic diagram of an application scenario of the embodiment of the present invention, and physical network devices are virtualized into MDC1, MDC2, and MDC3; MDC1 and MDC2 are mutual neighbor MDCs, and MDC2 and MDC3 are mutual neighbor MDCs.

[0053] Based on the above application scenarios, such as figure 2 As shown, the routing process management method based on virtual network equipment includes the following steps:

[0054] In step 201, the MDC determines that the present MDC and the neighbor MDC are located on the same physical network device.

[0055] In the embodiment ...

Abstract

The invention discloses a routing process management method and equipment based on a virtual network device. The method includes: when an MDC determines that the MDC and a neighbor MDC are located in the same physical network device, determine that the MDC is an MPR or an SPR in the physical network device; If it is MPR, the MDC does not switch the main control board for the routing process on the MDC; if it is SPR, the MDC judges whether the MDC and the MPR are neighbors; When the main control board is processing, the MDC switches the routing process on this MDC to other main control boards; if not, the MDC decides to switch the routing process on this MDC to another main control board or not to switch the main control panel. In the embodiment of the present invention, GR processing failure can be avoided, and resource utilization can be improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a routing process management method and device based on a virtual network device. Background technique [0002] MDC (MultitenantDeviceContext, multi-tenant device environment) technology is a 1:N network device virtualization technology, which can virtualize one physical network device into multiple logical network devices through software. The virtualized logical network device is referred to as MDC. Through the cooperation of software and hardware virtualization, MDC has complete equipment functions and independent software environment and data. [0003] GR (Graceful Restart, Graceful Restart) is a technology that ensures uninterrupted forwarding services during active-standby switchover or protocol restart. The core of GR is that a network device can notify its neighbor network devices when performing active-standby switchover or protocol restart. Keep the neigh...
