Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below with reference to the accompanying drawings and examples.

[0020] The embodiment of the present application provides a data message forwarding method, which is applied to the BRAS in the VRRP backup group in the VSRP network. When the BRAS is used as the backup device, when it receives the host route released by the active BRAS, it generates the corresponding host routing table entry. , when the BRAS switches to the master device, forward the received data message according to the corresponding host routing table entry. During active / standby switchover, this solution can improve the convergence speed of the VSRP network.

[0021] For the convenience of description, in a VRRP backup group, the BRAS serving as the master device is called the master BRAS, and the BRAS serving as the backup device...

Abstract

The invention provides a data message forwarding method. The method comprises: when a broadband remote access server (BRAS) serving as standby equipment receives a host route issued by a primary BRAS, a host route entry corresponding to the host route is generated; and when the BRAS is switched to be primary equipment and receives a data message, searching is carried out in the host route entry according to a destination IP address of the data message and then the data message is forwarded based on a searched outbound interface in the host route entry. On the basis of the same inventive concept, the application also brings forward a data message forwarding apparatus. When primary and standby equipment switching is carried out, the virtual service redundancy protocol (VSRP) networking convergence rate can be improved according to the technical scheme.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a data message forwarding method and device. Background technique [0002] In the virtual service redundancy protocol (Virtual Service Redundancy Protocol, VSRP) network of dual-machine backup, two broadband remote access servers (Broadband Remote Access Server, BRAS) are connected through the Virtual Router Redundancy Protocol (Virtual Router Redundancy Protocol) , VRRP) protocol to negotiate the master-standby relationship, with one BRAS as the master device and one BRAS as the backup device. [0003] When the BRAS serving as the standby device receives the host route released by the BRAS serving as the master device, it does not generate a host routing table entry, that is, the control plane does not deliver the host route to the data plane. [0004] When performing bidirectional forwarding detection (Bidirectional Forwarding Detection, BFD) detection, when it is detect...
