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...
