Problems solved by technology

[0009] If the VLAN to which the flooded traffic belongs has no corresponding configuration in the peer site, flooding to the peer site will have no effect. Instead, it will only increase the traffic burden on the EVI tunnel, which may cause other unicast packets to be congested. unable to transfer normally

Embodiment Construction

[0056] In view of the above-mentioned problems in the prior art, the embodiment of the present application provides a technical solution for broadcast message forwarding, which is applied to an EVI network including more than two sites. Each site of the EVI network includes an edge device and an access device. Each site The edge devices are connected through the EVI-LINK interface. In this technical scheme, the edge device of the site maintains the VLAN bitmap of the virtual local area network of the device, and the VLAN bitmap includes the VLANs allowed by other ports of the edge device except the EVI-LINK interface; The edge device of the site advertises the VLAN bitmap maintained by itself, and receives the VLAN bitmap advertised by the edge device of the adjacent site; the edge device of the site is configured according to the active VLAN on the EVI-LINK interface of the device, and the EVI-LINK interface receives the VLAN bitmap. The VLAN bitmap advertised by the edge dev...

Abstract

The invention discloses a broadcast message forwarding method and equipment. The method comprises: an edge device of a site maintains a virtual local area network (VLAN) bitmap of the device, and the VLAN bitmap includes other components of the edge device except the EVI‑LINK interface. The VLAN allowed by the port; the edge device of the site advertises the VLAN bitmap maintained by itself to the edge device of the adjacent site, and receives the VLAN bitmap advertised by the edge device of the adjacent site; the edge device of the site according to this device The active VLAN configuration on the EVI-LINK interface and the VLAN bitmap received by the edge device of the adjacent site on the EVI-LINK interface determine the VLANs that the EVI-LINK interface is allowed to pass through, and when receiving intra-site access When the device forwards the broadcast message of the corresponding VLAN, it forwards the broadcast message through the corresponding EVI‑LINK interface. In the present invention, the broadcast message of the EVI link is reduced.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a broadcast message forwarding method and device. Background technique [0002] EVI (Ethernet Virtual Interconnection, Ethernet Virtual Interconnection) is a "MAC (Media Access Control, Media Access Control) in IP (Internet Protocol, Internet Protocol)" technology, used to implement L2VPN (Layer2Virtual Private Network) based on IP core network Networks, Layer 2 virtual private network) technology. EVI only maintains routing and forwarding information on the edge devices of the site, without changing the routing and forwarding information of the site's internal and core networks. [0003] After deploying EVI, the network consists of core network, site network, and EVI network. [0004] Site network: A layer-2 network with independent business functions connected to the core network through one or more edge devices, usually managed and controlled by a single organi...
