Abstract

The invention provides a network fault handling method and provider edge routers (PEs). The network fault handling method comprises the following steps that: a first PE sends an MDT-Join (Multicast Distribution Tree-Join) message to a second PE within a preset range, and judges whether a first message sent by the second PE is received or not within a preset time, wherein the first message is a message sent by the second PE after a failure in creating a de-encapsulation table of the received MDT-Join message; and if so, the first PE stops switching from Default-MDT (Default-Multicast Distribution Tree) to Data-MDT (Data-Multicast Distribution Tree). Through adoption of the network fault handling method and the PEs, the problem of cutoff of customer multicast streams in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a network fault processing method and an edge device of a service provider. Background technique [0002] A virtual private network (Virtual Private Network, referred to as VPN) refers to providing a dedicated network for users in a public network without setting up a special physical link. The VPN consists of the core router (ProviderRouter, P for short) of the service provider network, the edge device (ProviderEdgeRouter, PE for short) of the service provider, and the edge device (CustomerEdgeRouter, CE for short) of the user network. Connection, the PE device is connected to the P device or CE device, and the CE device is connected to the PE device or the user network. [0003] Multicast VPN is a technology based on Multi-Protocol Label Switching (Multi-Protocol Label Switching, referred to as MPLS) network border gateway protocol (Border Gateway Protocol, referred to a...
