Abstract

The present invention discloses a method and device for processing a virtual route forwarding instance, wherein the method includes: receiving one or more network protocol IP addresses of the opposite end notified by the opposite end; combining the IP address of the local end with the IP address of the opposite end The IP addresses are paired to form multiple paths; the IP address of the opposite end of each path traverses the routing tables of all virtual routing and forwarding instance VRFs to find an effective VRF; sends a detection message to the effective VRF of the path, and receives Marking the VRF as activated after the response message to the detection message. The invention solves the problem in the related art that SCTP multi-homing cannot be deployed in multi-VPN networks, and achieves the effect of deploying SCTP multi-homing in multi-VPNs.

Description

Technical field [0001] The present invention relates to the field of network communication technology, in particular, to a method and device for processing virtual routing and forwarding instances. Background technique [0002] The Virtual Private Network (VPN) technology can protect the private information transmitted on the public network from being stolen and tampered with, thereby opening up a secure private network on the insecure Internet public network. Therefore, it is gaining more and more attention. More and more applications. In a VPN network device based on Multi-Protocol Label Switch (MPLS), the device is generally divided into multiple Virtual Route Forwarding Instances (VRF) based on interfaces, and each VRF corresponds to A VPN private network is identified by VrfName or VrfID number. Different VRFs are isolated from each other and cannot communicate. [0003] In some protocols, the multi-homing function is supported. The multi-homing function is a connection that...
