虚拟专用局域网业务VPLS的数据帧的转发方法、设备和系 Forwarding Virtual Private LAN Service VPLS data frames, equipment and lines

技术领域 FIELD

[0001] 本发明涉及通信技术领域,尤其涉及一种虚拟专用局域网业务VPLS的数据帧的转发方法、设备和系统。 [0001] The present invention relates to communication technologies, particularly to a method for forwarding data frames Virtual Private LAN Service VPLS, apparatus, and systems.

背景技术 Background technique

[0002] VPLS (Virtual Private Local Area Network Service,虚拟专用局域网业务) 是一种利用WAN(Wide Area Network,广域网)架构来虚拟以太局域网的技术。 [0002] VPLS (Virtual Private Local Area Network Service, Virtual Private LAN Service) is a technology to use virtual Ethernet LAN WAN (Wide Area Network, Wide Area Network) architecture. 它能够在MPLS (Multi-Protocol Label Switching,多协议标签交换)网络上提供类似于LAN (Local Area Network,局域网)的多点到多点连接,便于用户从多个地理位置分散的点同时接入MPLS网络,并相互访问,就像这些点直接接入到LAN上一样。 It is possible to provide similar LAN (Local Area Network, LAN) multi-multipoint connection, user's location from a plurality of dispersion on MPLS (Multi-Protocol Label Switching, MPLS) network access point at the same time MPLS network, and access each other, as if they were the same access point directly to the LAN. 由于目前核心网络主要都采用1P/MPLS技术,所以通过VPLS来提供虚拟以太网业务的需求越来越多,其部署也已经非常广泛。 Due to the current core network mainly are used 1P / MPLS technology, it provides a virtual Ethernet VPLS services by growing demand, it has also been very widely deployed.

[0003] 当以太网业务为组播业务或者当以太帧的目的地址未知时,传统VPLS通常采用复制转发的方法,即Root PE(Provider Edge,运营边缘设备)将以太帧复制多份并通过点对点的PW(PseUdo Wire,伪线)向每个对端PE发送一份拷贝。 [0003] When the Ethernet traffic or multicast service, when the destination address of the Ethernet frame is not known, commonly used method of copying traditional VPLS forwarding, i.e. Root PE (Provider Edge, operating edge device) multiple copies of an Ethernet frame through the point the PW (pseUdo wire, PW) for sending a copy to each of the remote PE. 但是在这种方式下,VPLS网络带宽消耗正比于叶子PE的数量,因此,其网络扩展性受到极大限制,网络运营成本很高。 In this manner, however, the VPLS network bandwidth consumption is proportional to the number of leaf PE, therefore, the network scalability is greatly limited, high costs of network operation.

[0004] 另外VPLS的VSl (Virtual Switch hstance,虚拟交换实例)转发器,通常采用了类似于传统以太网的自学习机制,其过程是,当一个以太帧通过一条PW到达VSI转发器,并且该帧的源MAC地址未知,那么该地址就与该PW关联在一起,作为转发表项保存在VSI转发器的MAC转发表中,以后VSI转发器发送到该地址的帧就通过该PW来传送。 [0004] Further the VPLS VSl (Virtual Switch hstance, virtual switch instance) transponder, usually similar to the traditional Ethernet self-learning mechanism, the process is, when an Ethernet frame through a repeater PW reaches the VSI, and the frame source MAC address is unknown, then the address is associated with the PW together as item will be transmitted through the PW stored in the MAC forwarding VSI of the transponder, the transponder after transmission VSI to the frame forwarding address.

[0005] 在IETF的L2VPN工作组,目前有一篇工作组文稿讨论了L2VPN的组播相关技术( draft-ietf-12vpn-vpls-mcast-05),它描述了一种通过VPLS网络进行组播的技术。 [0005] In the IETF L2VPN Working Group, a working group document currently discussed multicast related art L2VPN (draft-ietf-12vpn-vpls-mcast-05), which describes a multicast network through the VPLS technology. 其正向,即由Root PE传送到叶子PE的方向,组播和未知单播地址的以太帧的洪泛都通过一种特殊构造的组播树(通常为点到多点P2MP的PW)来传送到所有叶子,而已知单播地址的以太帧则仍然通过点对点的P2PPW进行传送。 Its forward, i.e. to the direction of transport by the Root leaf PE of PE, and multicast Ethernet frames flooding unicast address through a special multicast tree configuration (usually the multipoint P2MP PW) to sent to all the leaves, which is known unicast address of the Ethernet frame is still transmitted through P2PPW point to point. 但其反向,即由叶子传送到Root PE的方向,则还都是通过P2P PW传送数据帧。 But the reverse, i.e. the direction of conveying the leaves to the Root PE, then the data frames are also transmitted through the P2P PW.

[0006] 在实现本发明的过程中,发明人发现该现有技术存在如下缺陷: [0006] During the implementation of the present invention, the inventors found that the prior art has the following disadvantages:

[0007] 由于正向组播和反向单播的不对称,叶子PE无法正常地通过MAC地址自学习来构造其二层转发表,因此,叶子PE需要在转发平面修改自学习机制,需要所有叶子PE支持新的以太转发平面。 [0007] Since the forward multicast and unicast reverse asymmetry, leaf PE can not normally by MAC address self-learning to construct its Layer 2 forwarding table, therefore, leaves PE need to modify the forwarding plane self learning mechanism, it is necessary for all leaf PE support new Ethernet forwarding plane. 这就需要设计和开发新的转发引擎,PE设备成本很高。 This requires the design and development of new forwarding engine, a high PE equipment costs.

具体实施方式 Detailed ways

[0022] 下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。 [0022] below in conjunction with the present invention in the accompanying drawings, technical solutions of embodiments of the present invention are clearly and completely described, obviously, the described embodiments are merely part of embodiments of the present invention, but not all embodiments example. 基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获取的所有其他实施例,都属于本发明保护的范围。 Based on the embodiments of the present invention, all other embodiments of ordinary skill in the art without creative efforts made acquired, it falls within the scope of the present invention.

[0023] 如图1所示,本发明实施例提供的虚拟专用局域网业务VPLS的数据帧的转发方法,包括:接收静态MAC地址安装消息,所述静态MAC地址安装消息包含所述VPLS的组播源端口所对应的媒体访问控制MAC地址;解析所述静态MAC地址安装消息获取所述MAC地址;安装所述MAC地址到静态转发表;当从叶子客户接收到数据帧时,根据所述静态转发表转发所述数据帧。 [0023] As shown in FIG 1, a method for forwarding data frames VPLS Virtual Private LAN service according to an embodiment of the present invention, comprising: receiving a message to install a static MAC address, the MAC address of the installation static VPLS multicast message containing the source port corresponding media access control MAC address; parsing the static MAC address MAC address of the acquired message mounted; mounted to the static MAC address forwarding table; when receiving a data frame from the leaves to the client, according to the static switch published forwarding the data frame. 使用该方法,每个叶子PE无需修改转发平面,即可支持VPLS组播业务, 降低了设备成本。 Using this method, each leaf PE without modifying the forwarding plane, VPLS can support multicast services, reducing equipment costs. 从而既能够使得传统的VPLS PE设备能够立即实现VPLS组播,既能兼容于原有VPLS组播模型下的PE设备,也能够在一般转发平面的PE上进行实现,有利于实现VPLS网络的无缝升级,又降低了网络升级部署的复杂性。 Which not only enables conventional VPLS VPLS multicast PE device can be realized immediately, not only compatible with the original PE device VPLS multicast model can be performed on a general forwarding plane implemented in PE, it is conducive to free VPLS network seam upgrade, but also reduces the complexity of the network upgrade deployment.

[0024] 下面通过如图2所示的一个网络场景来加以详细说明本发明实施例,图中,PE1、 PE2和PE3构成一个VPLS网络,以太组播源R连接到PEl,因此PEl为Root PE,两个组播叶子Ll和L2分别连接到叶子PE2和PE3。 To be a network scenario shown in [0024] As shown by the following detailed description of embodiments of the present invention, FIG, PE1, PE2 and PE3 constitute a VPLS network, the Ethernet multicast source PEl R is connected to, so as Root PE PEl , two multicast leaves Ll and L2 are respectively connected to the leaf PE2 and PE3. 在提供组播业务前,在PEl到PE2和PE3之间建立一棵组播树PW0,并且在PEl和PE2、PEl和PE3之间分别建立单播PW(PWl和PW2),PE2和PE3之间可以建立PW(PW3),也可以不建立PW。 Prior to providing the multicast service, establishing a multicast tree in PEl PW0 between PE2 and PE3, and between unicast PW (PWl and PW2), between PE2 and PE3 PEl and PE2, and PE3 respectively establishing PEl can establish PW (PW3), may not establish PW. 在优选的实现方式下,PEl通过控制信令或网络管理平台通过管理平面命令向PE2和PE3分别发送静态MAC地址安装消息,通告组播源R端口所对应的MAC地址(同时还可以选择性通告点对点伪线PWl或PW2的信息)。 In the preferred implementation, PEl sent via control signaling or through the internet network management commands to the management plane PE2 and PE3 respectively mounted static MAC address message, advertisement R multicast source port corresponding to the MAC address (and optionally also advertise PW PWl point information or the PW2). 当PE2和PE3接收到该静态MAC地址安装消息后,解析该静态MAC地址安装消息,判断该静态MAC地址安装消息是否包含与该MAC地址关联的点对点伪线P2P Pff信息,如果判断结果为是,则安装该MAC地址和P2P PW信息到静态转发表;判断结果为否,则根据发送该静态MAC 地址安装消息的根运营边缘设备Root PE地址或者该静态MAC地址安装消息中携带的Root PE地址,获取与该MAC地址关联的P2P Pff信息;安装该MAC地址和P2P Pff信息到静态转发表。 When PE2 and PE3 receives the static MAC address installation message, parsing the static MAC address of the installation message, it determines whether the static MAC address of the installation message contains P2P Pff information associated with the MAC address of the point pseudo wire, if the determination result is yes, the MAC address and P2P PW information is attached to the static forwarding; root operations edge device root PE address determination result is NO, the installation message based on the transmission of the static MAC address or the static MAC address mounting root PE address carried in the message, P2P Pff obtain information associated with the MAC address; MAC address and the installation of P2P Pff information to static forwarding.

[0025] 另外,图中的以太组播源R可能不是终端用户(或服务器),而是一台网桥设备,多个终端用户(或服务器)可以通过该网桥设备接入到PE1。 [0025] Further, in FIG Ethernet multicast source R may not be an end user (or server), but a bridge device, a plurality of end-users (or servers) can access the bridge device to PE1. 此时,PEl需要将这些终端用户(或服务器)所对应的MAC地址列表通过控制信令或网络管理平台通过管理平面命令通告到所有叶子PE上。 At this time, PEl these end-user needs (or server) corresponding to the advertised list of MAC addresses to all leaf PE through control signaling or through a network management platform management plane command.

[0026] 若有一个叶子(Li)发送的目的地址为以太组播源R端口对应MAC地址的以太单播帧进入PE2的VSI转发器,在MAC地址查找中,通过上述过程安装的静态转发表项得到其关联的P2P伪线PWl,然后将该以太单播帧通过该PWl进行传送。 [0026] If the destination address of a leaf (Li) transmitted from an Ethernet MAC multicast source address corresponding to R port Ethernet unicast frame into the transponder of PE2 VSI in the MAC address lookup, the process of installing the above-described static forwarding its associated item obtained P2P PW PWl, then the Ethernet frame is transmitted by unicast the PWl. 具体可以为:在分组封装时,首先插入P2P的PW标签(PWl标签),然后经过P2P的LSP隧道封装,再通过点对点伪线PWl传送到Root PE (PEl)上,PEl根据MAC地址将该以太单播帧发送到相应的Root端口。 It may be: when the packet encapsulation, is first inserted into the P2P PW label (label PWL), then through the P2P LSP tunnel encapsulation, and then transmitted to the Root PE (PEl) via a point pseudo wire PWl, PEl the Ethernet MAC address unicast frames are sent to respective Root port.

[0027] 本发明实施例二给出了以太组播源的MAC地址删除过程。 MAC address Example [0027] The present invention gives two Ethernet multicast source delete process. 当以太网组播业务停止,或者以太组播源的接入拓扑发生变化时,Root PE通过控制信令或者网络管理平台通过管理平面命令发送静态MAC地址删除消息,将原以太组播源端口所对应的MAC地址通告所有叶子PE,叶子PE接收到删除消息后,将所通告的MAC地址表项从静态转发表中删除。 When the Ethernet multicast service is stopped, or Ethernet multicast source access topology changes, Root PE static MAC address transmitted by the control signaling network management platform or the command to delete the message by a management plane, the original Ethernet multicast source port advertisement after the corresponding MAC address of all leaf PE, the PE receives leaf deletion message, the advertised MAC address entry is deleted from a static forwarding table.

[0028] 当以太组播源的接入拓扑发生变化时,在优化的实现方式下,上述RootPE也可以通过控制信令或者网络管理平台通过管理平面命令发送静态MAC地址重安装消息,将新的以太组播源端口所对应的MAC地址通告所有叶子PE,每个叶子PE接收到该消息后,将所通告的MAC地址表项从静态转发表中删除,并安装与新的以太组播源端口关联的新静态转发表项。 [0028] When the access topology Ethernet multicast source changes in an optimized implementation, the above-described static RootPE may be transmitted by the control signaling or MAC address network management platform through the message command to reinstall the management plane, a new after the Ethernet source port corresponding to the multicast MAC address announcement to all leaf PE, each PE receives the message leaves the advertised MAC address entry is deleted from a static forwarding table, and installs a new source port Ethernet multicast the new static correlation forwarding entry.

[0029] 本发明实施例通过扩展LDP信令来实现MAC地址安装和删除的实现方法。 Example [0029] The present invention achieves implemented method for installing and removing the MAC address by extending the LDP signaling. 目前LDP是建立PW的主要信令,因此以它为例加以说明。 At present the main LDP signaling the establishment of PW, so it as an example to illustrate this. 但是本发明所描述的机制同样也适用于BGP(Border Gateway Protocol,边界网关协议)等其它路由信令协议上。 However, the mechanism described in the present invention is also applicable to BGP (Border Gateway Protocol, BGP) and other routing signaling protocol.

[0030] 如图3和图4所示,分别给出了LDP协议下扩展的静态MAC地址安装和静态MAC 地址删除两种类型的消息格式。 [0030] FIGS. 3 and 4, respectively, given the extended LDP protocol and static MAC address is a static MAC address deletion mounting two types of message formats. 可选性地,PW信息可以携带在消息的选项参数字段上。 Optional ground, PW information may be carried on the options parameter field of the message. 静态MAC地址重安装的消息格式与此类似。 Static MAC address re-installation message format similar to this.

[0031] 首先,当一个支持组播的VPLS在所有PE之间建立PW时,若Root PE与叶子PE是通过LDP信令建立它们之间的以太网伪线,则Root PE可通过图3的消息格式发送静态MAC 地址安装消息,即,通过一个TLV(Type Length Value,类型长度值)携带所要通告的一个或多个以太组播源端口所对应的MAC地址表,它还可选择进一步携带一个TLV选项,携带它所对应的PW信息。 [0031] First, when a multicast support VPLS PW established between all PE, and a leaf PE if PE Root to establish an Ethernet pseudo wire between them through LDP, PE by the Root FIG. 3 message format message transmission installation static MAC address, i.e., by means of a TLV (type length value, type length value) carries the MAC address table of one or more Ethernet ports to be advertised multicast sources corresponding to the further optionally a further bearing TLV option carries its corresponding PW information.

[0032] 当Leaf PE接收到静态MAC地址安装消息后,解析该消息以及它所携带的TLV,首先它解析得到以太组播源端口所对应的MAC地址集,若消息中携带有包含PW信息的选项TLV,则将相应的〈Root MAC, PW>作为MAC转发表项安装到静态转发表。 [0032] When receiving Leaf PE static MAC address installation message, parses the message and TLV carried in, it is first parsed MAC address set corresponding to the Ethernet multicast source port, if the message carries information contained PW options TLV, then the corresponding <Root MAC, PW> as the MAC forwarding entry to install static forwarding. 否则,它根据发送该静态MAC地址安装消息的根运营边缘设备Root PE地址(源IP地址)或者该静态MAC 地址安装消息中携带的Root PE地址,获取对应于该IP地址的唯一P2P Pff信息;最后将〈Root MAC, Pff>作为MAC转发表项安装到静态转发表。 Root operating edge device Root PE address Otherwise, its installation messages based on the transmission of the static MAC address (source IP address) or the static MAC address mounting Root PE address carried in the message, acquires unique P2P Pff information corresponding to the IP address; Finally, the <Root MAC, Pff> as the MAC forwarding entry to install static forwarding. 若MAC地址集包含多个地址,则按上述过程安装多个静态转发表项。 If the MAC address set contains a plurality of addresses, the above-described process of mounting a plurality of press static forwarding entries.

[0033] 当组播业务停止时,Root PE可通过图4的消息格式发送静态MAC地址删除消息, 即,通过一个TLV携带所要通告的一个或多个以太组播源端口对应的MAC地址表。 [0033] When the multicast service is stopped, Root PE message may be deleted by the static MAC address message format in FIG. 4, i.e., by a TLV carrying one or more Ethernet source port corresponding to the multicast MAC address to be advertised.

[0034] 当Leaf PE接收到静态MAC地址删除消息后,解析该消息以及它所携带的TLV,得到以太组播源端口所对应的MAC地址表,然后将所对应的一个或多个MAC转发表项从静态转发表中删除。 [0034] When receiving Leaf PE static MAC address deletion message, parses the message, and a TLV carried by it, to obtain the Ethernet MAC address table corresponding to the multicast source port, and then one or more MAC forwarding table corresponding removed from a static forwarding table.

[0035] 本发明又一实施例给出了在Root主备保护以及负载分担下的VPLS组播实施例。 [0035] A further embodiment of the present invention are given VPLS multicast standby protection and load sharing under the Root embodiment. 如图5所示,两个组播源Root设备和多个leaf设备分别通过PE设备接入VPLS网络,并且在VPLS网络中为该客户的组播业务配置了两棵组播树,通过它们两个Root设备可以为所有的leaf设备提供组播服务。 5, the two devices and the plurality of multicast source leaf Root devices respectively connecting the PE to the VPLS network, and VPLS network is configured with two multicast tree for the multicast service customer, through which two a Root device can provide multicast services for all leaf devices.

[0036] 在Root主备保护模式下,一般指定一个Root作为工作Root,而另一个Root作为保护Root。 [0036] In the Root standby protection mode, generally designated as a Root Root work, and the other as a protective Root Root. 正常情况下,只有工作Root进行组播,而保护Root并不提供组播服务。 Under normal circumstances, only the work Root multicast, and multicast service does not provide protection Root. 在提供组播业务之前,工作Root PE按照上述实施例所述过程在所有叶子PE上安装自己的静态MAC地址表项使其关联到对应于自己的PW,这样,正常时只有工作Root PE能够接收到叶子所发送的单播报文。 Before providing a multicast service, the Working Root PE of the process according to the above embodiment is mounted on all leaf PE own static MAC address entries associated with it corresponding to the PW own, so that, during normal working Root PE can receive only to unicast packets sent by the leaves. 一旦工作Root出现故障(例如,设备出现故障或者接入链路出现故障),那么保护Root则接替提供组播服务。 Once the work Root failure (eg, equipment failure, or an access link fails), then the protection Root will succeed to provide multicast services. 同时,保护Root PE按照上述实施例过程发送重安装消息并在每个叶子PE上安装新的静态MAC地址表项,使其关联到对应于自己的新PW, 并使得叶子PE的单播报文发送到保护Root上。 At the same time, protect the Root message PE sending heavy installation and install a new static MAC address entries on each leaf according to the above procedure of Example PE, associate it to the PW corresponding to their new, and that the leaf PE unicast packet transmission to the protection Root.

[0037] 在Root负载分担模式下,两个(或更多个)Root同时能够提供组播业务,也都能够处理来自叶子的单播报文。 The [0037] Root in load sharing mode, two (or more) Root while providing the multicast service, also capable of handling multicast packets from a single leaf. 在提供组播业务之前,Root PE或者网络管理平台在一部分叶子PE上安装对应于Rootl的静态MAC地址表项,而在另一部分叶子PE上则安装对应于Root2的静态MAC地址表项,从而使得各个leaf PE的反向单播路径分别指向两个不同的Root ΡΕ,从而达到一个Root为一部分leaf服务,而另一个Root则为另一部分leaf服务的目的。 Before providing a multicast service, or a network management platform Root PE corresponding to Rootl mounted static MAC address entries on a portion of a leaf PE, while another portion of the installation corresponds to a leaf PE static MAC address entries Root2 such that unicast reverse path to each leaf of the PE point to two different Root ΡΕ, so as to achieve as part of a leaf Root service, while another portion of the other leaf Root object services compared. 信令可以采用如上述实施例的消息形式。 In the form of a signaling message as described in Example may be employed. 如果是点对点的控制信道,则只需要提供相应的MAC地址和PW即可;如果是广播控制信道(例如BGP),则还需要在信令中携带叶子组信息(例如只安装到叶子组1,只安装到叶子组2,或者安装到全体叶子组),以便叶子PE能够根据叶子组信息和自己的叶子组ID来决定是否安装静态MAC地址表项,只有叶子组信息和其叶子组ID匹配的那些叶子PE才安装相应的转发表项。 If the control channel is a point, need only provide the appropriate MAC address and can PW; if it is a broadcast control channel (e.g., the BGP), is also required to carry signaling information leaf group (e.g., a leaf mounted to only one group, only mounted to the leaf pack 2, or attached to the whole leaves group), so that the leaf PE is able to decide whether to install a static MAC address entry according leaves group information and their leaves group ID, only leaves group information and which leaves the group ID matches PE those leaves only install the appropriate forwarding entry.

[0038] 通过上述实施例,本发明实施例能很容易的实现Root的主备保护和负载分担。 [0038] By the above-described embodiments, embodiments of the present invention can easily achieve the Root standby protection and load balancing.

[0039] 对于城域以太网论坛MEF组织定义的E-1Tree业务(E-1Tree是MEF定义的一种通用的新业务,是VPLS组播技术的一种重要应用场景,它具有如下特性:Root到Leaf为一对多关系,并可能存在多个Root设备;Root可发送信流到任意Root和Leaf,Leaf也可发送到任何Root ;Leaf和Leaf之间不能连通,需要信流隔离。),其leaf和leaf之间不能有信流连通,需要进行信流隔离,而叶子只可以将报文发送到一个或多个Root。 [0039] For Metro Ethernet Forum MEF-defined E-1Tree tissue business (E-1Tree MEF is a common definition of new business, is an important application of the VPLS multicast technology, it has the following characteristics: Root Leaf to many relationship, and there may be a plurality of devices Root; Root flow channel can transmit and any Leaf Root, Leaf Root may be sent to any; and not communication between Leaf Leaf, isolated from the flow channel needs). can not have between leaf and leaf flow communication channels, need to be isolated from the flow channel, and leaves can only send packets to one or more Root. 这可以通过本实施例的方法来加以解决:首先,在业务传送之前,在所有叶子PE的VSI上安装一条特殊的静态转发表项(它关联于一条或多条PW,每条PW对应于一个Root ΡΕ);当叶子PE的VSI从叶子客户接收到组播、广播帧或未知目的地址的单播帧时,则通过上述特殊静态转发表项对该帧进行转发。 This can be by the method according to the present embodiment is solved: First, before service delivery, the installation of a special static forwarding entries (which is associated with one or more leaf PE PW on all of the VSI, each corresponding to a PW root ΡΕ); when a unicast frame is received from a VSI leaf PE to the client leaves a multicast, broadcast frames or unknown destination address, through the above-described special static forwarding entries to the forwarding frame. 这样一来,各个叶子PE相互之间无分组洪泛,一方面实现了叶子隔离,另一方面避免学习到其它叶子的MAC地址,提高了网络的扩展性。 Thus, each leaf PE no flooding packets to each other, on the one hand to achieve isolation leaves, on the other hand to avoid learning MAC addresses of other leaves, improve the network scalability.

[0040] 这种特殊静态转发表项的安装和删除可以采用如下方法:例如,令MAC地址的数值为O或其他特殊值表示这种特殊表项,而静态MAC地址安装消息携带一条或多条PW信息。 [0040] This special static forwarding entries installation and removal method may be employed: For example, let the value of this particular MAC address table entry represents O or other special values, while static MAC address message carries one or more mounting PW information. 当接收到静态MAC安装消息,并且其MAC地址数值为O或其他特殊值,则安装相应的特殊静态转发表项。 Upon receiving the install static MAC message and the MAC address value of O or other special values, corresponding special installation static forwarding entries. 当接收到静态MAC地址删除消息,并且其MAC地址数值为O或其他特殊值,则将该特殊静态转发表项删除。 When receiving the deleting message static MAC address, its MAC address and a value of O or other special value, the special static forwarding entries to delete.

[0041] 使用本发明实施例的方法,每个叶子PE无需修改转发平面,即可支持VPLS组播业务,降低了设备成本。 [0041] Using a method embodiment of the invention, each leaf PE without modifying the forwarding plane, to support VPLS multicast services, less costly equipment. 从而既能够使得传统的VPLS PE设备能够立即实现VPLS组播,既能兼容于原有VPLS组播模型下的PE设备,也能够在一般转发平面的PE上进行实现,有利于实现VPLS网络的无缝升级,又降低了网络升级部署的复杂性。 Which not only enables conventional VPLS VPLS multicast PE device can be realized immediately, not only compatible with the original PE device VPLS multicast model can be performed on a general forwarding plane implemented in PE, it is conducive to free VPLS network seam upgrade, but also reduces the complexity of the network upgrade deployment.
