Message processing method, access equipment and communication system

Abstract

The embodiment of the invention relates to a message processing method, access equipment and a communication system. In the message processing method, the access equipment receives a network-side multicasting message through a first network port of the access equipment; the access equipment identifies the protocol type of the multicasting message; if the identified multicasting message is a virtual router redundancy protocol (VRRP) message, the virtual router redundancy protocol message is sent to a network side through a second network port of the access equipment according to an interception port list used for transmitting the virtual router redundancy protocol message; and if the identified multicasting message is a non-virtual router redundancy protocol message, the non-virtual router redundancy protocol message is sent to a user side through a user port of the access equipment. The embodiment of the invention can prevent the access equipment from broadcasting the VRRP message to all users so as to save the network bandwidth, and prevent the users from attacking a router by intercepting the VRRP message and constructing a VRRP message with high priority level so as to enhance the network safety and ensure the normal operation of services.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to a packet processing method, access equipment, and a communications system. Background technique [0002] In network applications, in order to communicate with networks in different network segments, the host needs to set a default gateway, and all messages in this network segment can be forwarded to other network segments through the default gateway. When the gateway fails, the communication between the entire host and the external network will be interrupted. In the Virtual Router Redundancy Protocol (VRRP for short), there is no need to change the networking situation, nor do any configuration on the host, and only a few commands are configured on the relevant routers. Realize the backup of the next-hop gateway without burdening the host. Compared with other methods, VRRP has the advantages of simple configuration, convenient management, ...
