· BIER域和BIER子域：网络中所有BFR的集合称为BIER域（Domain）。一个BIER域可以划分为一个或者多个BIER子域（Sub-domain）。通过Sub-domain ID来区分不同的BIER子域。
· BFR ID：用来在一个BIER子域中唯一标识一台BIER边缘设备，Transit BFR无需配置BFR ID。
· BFR prefix：相当于路由协议中的Router ID，用来标识BIER节点。在同一个BIER子域中，每个BFR必须配置唯一的BFR前缀，且该前缀必须是BIER子域内路由可达的。目前只支持配置为Loopback口的地址。
· Bit String（Bit String，比特串）：BIER用一个特定长度的BS来表示BIER边缘设备。Bit String从最右边开始，每一个比特位对应一个BFR ID。比特串的长度用BSL（Bit String Length）来表示。比如，使用一个BSL为3的比特串来最多标识一个BIER子域内三个BIER边缘设备，那么“001”就表示BFR ID为1的BIER边缘设备。
· SI（Set Identifier，集标识）：在BIER中，当使用的BSL长度不足以表示一个BIER子域内配置的BFR ID的最大值时，需要将Bit String分成不同的集合，每个集合通过SI来标识。
· BIRT（Bit Index Routing Table，位索引路由表）：BIRT是通过IGP协议携带BIER信息（Sub-domain、BSL、BFR ID）在网络上进行泛洪，并根据IGP传递的BIER信息和路由信息生成。
· F-BM（Forwarding-Bit Mask，转发位串掩码）：F-BM用来表示往下一跳邻居复制发送组播报文时，通过该邻居能到达的BIER子域边缘节点集合。通过将该邻居所能到达的所有BIER子域边缘节点的Bit String进行“或”操作后得到。
· BIFT（Bit Index Forwarding Table，位索引转发表）：BIER子域内的组播流量通过查询BIFT来实现逐跳转发。每张BIFT都由三元组（BSL，SD，SI）唯一确定。BIFT是通过将BIRT表项中到达相同邻居不同表项进行合并生成，生成F-BM与该邻居对应的表项。
(1) 组播源侧PE首先通过与接收者PE交互BGP MVPN路由，获知组播流量需要发送给哪些接收者侧PE。
(2) 组播源侧PE和接收者侧PE之间通过BGP报文中携带的Intra-AS I-PMSI A-D Route、S-PMSI A-D Route和Leaf A-D Route三大路由信息传递BIER信息（BFR ID、Sub domain ID、BFR prefix）。
(3) 组播数据根据PIM路由表由CE传输到PE上的相容性隧道时完成了私网到公网的无缝连接，组播源侧PE将收到私网组播数据封装BIER头后，通过相容性隧道传输给远端PE，远端PE收到该报文后通过剥离标签信息将其还原成私网组播报文。
(4) 当组播源侧PE上有满足切换选择性隧道条件的组播流量时，建立选择性隧道，并通过选择性隧道传输封装了BIER头的私网组播数据。
BIER模式的MVPN中，使用BIER作为公网承载隧道，将组播私网流量通过BIER封装，发送给BIER子域内的其他各节点。
组播源侧PE首先通过与接收者PE交互BGP MVPN路由，获知组播流量需要发送给哪些接收者侧PE，此过程与RSVP-TE和mLDP模式的MVPN类似，区别在于Intra-AS I-PMSI A-D Route、S-PMSI A-D Route和Leaf A-D Route中将会携带BIER信息（BFR ID、Sub domain ID、BFR prefix）。关于RSVP-TE和mLDP模式MVPN的详细介绍，请分别参见“IP组播配置指导”中的“RSVP-TE模式MVPN”和“mLDP模式MVPN”。
组播源侧PE将收到的私网组播流量封装Bit String后，在公网内进行BIER转发。有关BIER转发的详细介绍，请参见“BIER配置指导”中的“BIER”。
与RSVP-TE和mLDP类似，组播数据根据PIM路由表由CE传输到PE上的相容性隧道时完成了私网到公网的无缝连接，私网组播数据通过相容性隧道传输给远端PE，远端PE收到该报文后通过剥离标签信息将其还原成私网组播报文。当组播源侧PE上有满足切换选择性隧道条件的组播流量时，建立选择性隧道。
BIER支持多种封装类型，不同封装类型的BIER模式MVPN工作过程相似，但封装时使用的BIER报文头格式略有不同。关于BIER不同封装类型的详细介绍，请参见“BIER配置指导”中的“BIER”。
如图1-1所示，私网侧采用PIM协议，公网为BIER网络。在PE 1、PE 2和PE 3上均部署了BGP和MVPN之后，相容性隧道的创建过程如下：
(1) PE 1向PE 2和PE 3发送1类路由Intra-AS I-PMSI A-D Route，该路由携带以下信息：
¡ Route Target：用于控制路由的发布和接收，配置为PE 1的Export Target。
¡ PMSI Tunnel attribute，用于传递隧道信息。其中，Tunnel Type字段取值为BIER隧道，并携带PE 1的BIER信息（Sub domain ID、BFR ID、BFR prefix）。
(2) PE 2和PE 3接收到PE 1发送的1类路由后，检查此路由中的Route Target属性与本地VPN实例配置的Import Target是否匹配。如果匹配，则接收此路由。同时向PE 1回复4类路由Leaf A-D route，该路由携带以下信息：
¡ Route Target：用于控制路由的发布和接收，配置为PE 2或者PE 3的Export Target。
¡ PMSI Tunnel attribute，用于传递隧道信息。其中，Tunnel Type字段取值为BIER隧道，并携带各自与PE 1处于相同BIER子域的BIER信息（通过PE 1发送的1类路由中获取到的Sub domain ID查找到本地相同的子域中，配置的BFR ID和BFR prefix）。
(3) PE 1收到PE 2和PE 3发送的4类路由后，检查此路由中的Route Target属性与本地VPN实例配置的Import Target是否匹配。如果匹配，则接收此路由。将PE 2和PE 3记录为MVPN的成员。同时，根据收到的4类路由中携带的BFR ID和对应BIER子域内配置的BSL的值，计算得到SI。PE1将所有叶子的信息合并，就生成了对应的Bit String，即BIER类型的相容性隧道。
当相容性隧道接收到指定（S，G）表项的组播流量时，进行选择性隧道切换，实现了不同组播流量传输的隧道分离。一个VPN实例内允许存在多个选择性隧道。
如图1-2所示，创建选择性隧道并进行隧道切换的具体过程如下：
(1) PE 1向PE 2和PE 3发送3类路由S-PMSI A-D Route，该路由携带以下信息：
¡ Route Target：用于控制路由的发布和接收，配置为PE 1的Export Target。
¡ PMSI Tunnel attribute，用于传递隧道信息。其中，Tunnel Type字段取值为BIER隧道，并携带PE 1的BIER信息（Sub domain ID、BFR ID、BFR prefix）。
(2) PE 2和PE 3接收到PE 1发送的3类路由后，检查此路由中的Route Target属性与本地VPN实例配置的Import Target是否匹配。如果匹配，则接收此路由。如果下游存在接收者，则向PE 1回复4类路由Leaf A-D route，否则丢弃该路由。回复的4类路由携带以下信息：
¡ Route Target：用于控制路由的发布和接收，配置为PE 2或者PE 3的Export Target。
¡ PMSI Tunnel attribute，用于传递隧道信息。其中，Tunnel Type字段取值为BIER隧道，并携带各自与PE 1处于相同BIER子域的BIER信息（通过PE 1发送的1类路由中获取到的Sub domain ID查找到本地相同的子域中，配置的BFR ID和BFR prefix）。
(3) PE 1收到PE 2和PE 3发送的4类路由后，检查此路由中的Route Target属性与本地VPN实例配置的Import Target是否匹配。如果匹配，则接收此路由。将PE 2和PE 3记录为MVPN的成员。同时，根据收到的4类路由中携带的BFR ID和对应BIER子域内配置的BSL的值，计算得到SI。PE1将所有叶子的信息合并，就生成了指定（S，G）对应的Bit String，即BIER类型的选择性隧道。
NG MVPN over BIER场景下，使用BIER建立承载隧道，组播私网流量经过BIER封装后穿越公网发送到BIER子域其他各节点。
NG MVPN over BIER的控制平面包括以下特有的技术实现：
· 接收者PE信息收集
该场景中，组播源侧PE首先获知组播流量要发送给哪些接收者侧PE，然后组播源侧PE根据收到的私网组播流量封装Bit String。其中，MVPN中各PE成员的收集机制与RSVP-TE和mLDP模式下的MVPN过程类似。
· 新增BIER类型隧道属性
为了支持NG MVPN over BIER，RFC8556定义了在BGP MVPN业务中使用BIER隧道时所需要的信息，即一个BIER类型的PTA（PMSI Tunnel attribute，PMSI隧道属性）。在BGP MVPN业务使用BIER隧道时，使用上述BIER类型的PTA。其中，PTA的MPLS Label字段原本用于标识MVPN实例的上游分配标签，在基于BIER隧道的MVPN中不再使用该字段，而是使用一个新的BGP属性携带用于标识MVPN实例的IPv6源地址（组播服务源地址、src-dt4或src-dt6）。对于G-BIER，该BGP属性称为MSID（Multicast Service Identifier，组播服务ID）；对于BIERv6或MSR6，该BGP属性则称为Prefix-SID 。相应的，PTA中MPLS Label字段值则被设置为0。
在MVPN over G-BIER中，新增的BGP属性MSID用来标识MVPN实例，MSID中的组播服务源地址通过组播源侧PE在1类路由Intra-AS I-PMSI A-D route中携带，通告给接收者侧PE。接收者侧PE记录该源地址与MVPN实例的对应关系。当接收侧PE收到G-BIER封装的组播报文时，会通过报文中的组播服务源地址找到相应的MVPN实例，在对应的MVPN实例中找到对应的组播转发表项，并转发组播报文。
BGP MSID属性及其内容遵循BGP属性定义的格式要求，格式如图1-3所示。
MSID Attribute各字段的含义如下：
· Attribute Flags：8bits，属性标识。
· Attribute Type：8bits，属性类别字段，属性名为MSID。
· Attribute Length：16bits，属性长度。
· Attribute Data：可变长度，属性数据。采用无固定字段的Sub-TLV表示。
Attribute Data为无固定字段的Sub-TLV，具体格式如图1-4所示。
Sub-TLV各字段的含义如下：
· Sub-TLV Type：8bits，Sub-TLV类型。
· Sub-TLV Length：16bits，Sub-TLV长度。
· Reserved：8bits，保留字段。
· IPv6 address：IPv6源地址。
· sub-sub-TLV：可变长度，表示本Sub-TLV携带的sub-sub-TLV，目前仅支持Structure sub-sub-TLV。
Structure sub-sub-TLV的格式如图1-5所示。
Structure sub-sub-TLV各字段的含义如下：
· sub-sub-TLV Type：8bits，sub-sub-TLV类型，取值为1，表示Structure sub-sub-TLV。
· sub-sub-TLV Length：16bits，sub-sub--TLV长度，取值为5。
· Flags：8bits，标志字段用于后续扩展，目前要求为0。
· Prefix Length：8bits，前缀长度。
· MSID Length：8bits，组播服务ID的长度。
· Must Be Zero：16bits，保留字段。
在MVPN over BIERv6中，BGP属性Prefix-SID用来携带BIERv6隧道封装的IPv6源地址，BIERv6组播源侧PE通过在1类路由Intra-AS I-PMSI A-D route和3类路由S-PMSI A-D route中携带Prefix-SID，将隧道源地址通告给接收者侧PE。接收者侧PE收到1类和3类路由后，根据路由携带的Route Target属性匹配本地的VPN实例或公网实例，并记录路由携带的Prefix-SID与VPN实例或公网实例的对应关系。接收侧PE收到BIERv6封装的组播报文时，会根据报文中的BIERv6隧道源地址找到对应的VPN实例或公网实例，在VPN实例或公网实例对应的MVPN实例中建立组播转发表项，并转发组播报文。
BGP Prefix-SID属性及其内容遵循RFC标准定义的格式要求，格式如图1-6所示。
BGP Prefix-SID各字段的含义如下：
· TLV Type：TLV的类型。取值为5，表示SRv6承载的是三层业务；取值为6，表示SRv6承载的是二层业务。
· TLV Length：TLV的长度。
· Reserved：保留字段。
· SRv6 Service Sub-TLVs：Prefix-SID的相关业务信息，为可变长度。
SRv6 Service Sub-TLV包含如下字段：
· SRv6 Service Sub-TLV Type：Prefix-SID业务信息的类型，固定取值为1，表示SRv6 SID Information Sub-TLV。
· SRv6 Service Sub-TLV Length：SRv6 Service Sub-TLV的长度。
· SRv6 Service Sub-TLV Value：SRv6 Service Sub-TLV的取值，长度可变。
类型为SRv6 SID Information Sub-TLV时，SRv6 Service Sub-TLV包含如下字段：
· SRv6 Service Sub-TLV Type：SRv6 Service Sub-TLV的类型，固定取值为1。
· SRv6 Service Sub-TLV Length：SRv6 SID Information Sub-TLV的长度。
· Reserverd1：保留字段。
· SRv6 SID Value：Prefix-SID的值。表示BIERv6隧道源地址的Src.DT4 SID和Src.DT6 SID由此字段携带。
· SRv6 SID Flags：Prefix-SID的标记，固定取值为0。
· SRv6 Endpoint Behavior：Prefix-SID的类型。取值0x45表示Src.DT4 SID，取值0x44表示Src.DT6 SID。
· Reserverd2：保留字段。
MVPN的扩展团体属性主要用于C-multicast路由的发布和接收，包括以下两种类型：
· Source AS Extended Community：该属性用于标识组播源所在的AS号，用于跨域场景。
· VRF Route Import Extended Community：该属性用于标识组播源侧PE的IP地址以及组播源所在的VPN实例。
Source AS Extended Community以及VRF Route Import Extended Community在扩展团体属性中的格式分别如图1-7和图1-8所示。
图1-7 Source AS Extended Community的格式
Source AS Extended Community包含如下字段：
· Type：扩展团体属性的类型，取值为0x00（表示2字节AS号类型的扩展团体属性）或0x02（表示4字节AS号类型的扩展团体属性）。
· Sub-Type：扩展团体属性的子类型，取值为0x09，表示该扩展团体属性为Source AS Extended Communit。
· Global Administrator：组播源所在的AS号，可以是2字节形式的AS号，也可以是4字节形式的AS号。
· Local Administrator：取值为0，暂无特殊含义。
图1-8 VRF Route Import Extended Community的格式
VRF Route Import Extended Community包含如下字段：
· Type：扩展团体属性的类型，取值为0x01（表示IPv4地址类型的扩展团体属性）或无取值（表示IPv6地址类型的扩展团体属性）。
· Sub-Type：扩展团体属性的子类型，取值为0x0b（IPv4地址类型的扩展团体属性时的取值）或0x000b（IPv6地址类型的扩展团体属性时的取值），表示该扩展团体属性为VRF Route Import Extended Community。
· IPv4/IPv6 address：组播源侧PE的IP地址。
· Local Administrator：组播源所处的VPN实例。
如图1-9所示，PE 1和PE 2都是组播源测PE，PE 3为接收侧PE。PE 1和PE 2都与VPN 1以及公网实例的站点相连，PE 1上VPN 1的VRF Route Import Extended Community值为1.1.1.1:1；PE 1上公网实例的VRF Route Import Extended Community值为1.1.1.1:0（公网实例的VRF Route Import Extended Community中Local Administrator的值必须为0）；PE 1上Source AS Extended Community的值为10:0。PE 2上VPN 1的VRF Route Import Extended Community值为2.2.2.2:1；PE 2上公网实例的VRF Route Import Extended Community值为2.2.2.2:0（公网实例的VRF Route Import Extended Community中Local Administrator的值必须为0）；PE 1上Source AS Extended Community的值为10:0。
图1-9 MVPN扩展团体属性工作机制
PE 1和PE 2都与PE 3建立BGP MVPN地址族的BGP会话后，PE 1和PE 2都会向PE 3发布到组播源的单播路由信息，其中VPN实例的组播源单播路由信息通过BGP VPNv4或VPNv6路由携带，公网实例的组播源单播路由信息通过BGP IPv4/IPv6单播路由或BGP IPv4/IPv6组播路由携带。所有通告到组播源的单播路由信息的BGP路由均会携带Source AS Extended Community和VRF Route Import Extended Community。
PE 3接收到通告到组播源的单播路由信息的BGP路由后，会对BGP路由进行优选，然后将路由携带的Source AS Extended Community和VRF Route Import Extended Community存储下来，用于后续构造C-multicast路由。在本例中假设PE 3优选了来自PE 1的通告到VPN 1组播源的单播路由信息的BGP路由，以及优选了来自PE 2的通告到公网实例组播源的单播路由信息的BGP路由。
VPN实例VPN 1以及公网实例的C-multicast路由构造过程如下：
· 当PE 3收到来自CE 3的组播加入消息后，会构造C-multicast路由，然后向PE 1和PE 2发送，这个路由的Source AS字段为收到的Source AS Extended Community中的AS号，路由携带的Route Target属性为BGP优选路由的VRF Route Import Extended Community，即1.1.1.1:1。
¡ PE 1收到C-multicast路由后，对比C-multicast路由RT属性中携带的IP地址，发现是1.1.1.1，即本地的源接口地址，接收C-multicast路由。随即PE 1根据RT属性中的Local Administrator确定C-multicast路由属于VPN实例VPN 1，将C-multicast路由添加到VPN 1的组播路由表中。
¡ PE 2收到C-multicast路由后，对比C-multicast路由RT属性中携带的IP地址，发现是1.1.1.1，不是本地的源接口地址，丢弃C-multicast路由。
后续处于VPN 1的组播源发送组播报文时，由于仅PE 1形成了组播表项，组播报文会在PE 1进行BIER封装后通过BIER公网隧道发送到PE 3，在PE 3上进行解封装后转发到CE 3。
· 当PE 3收到来自CE 4的组播加入消息后，会构造C-multicast路由，然后向PE 1和PE 2发送，这个路由的Source AS字段为收到的Source AS Extended Community中的AS号，路由携带的Route Target属性为BGP优选路由的VRF Route Import Extended Community，即2.2.2.2:0。
¡ PE 2收到C-multicast路由后，对比C-multicast路由RT属性中携带的IP地址，发现是2.2.2.2，即本地的源接口地址，接收C-multicast路由。随即PE 2根据RT属性中的Local Administrator确定C-multicast路由属于公网实例，将C-multicast路由添加到公网实例的组播路由表中。
¡ PE 1收到C-multicast路由后，对比C-multicast路由RT属性中携带的IP地址，发现是2.2.2.2，不是本地的源接口地址，丢弃C-multicast路由。
后续处于公网实例的组播源发送组播报文时，由于仅PE 2形成了组播表项，组播报文会在PE 2进行BIER封装后通过BIER公网隧道发送到PE 3，在PE 3上进行解封装后转发到CE 4。
在实际组网应用中，当一个VPN跨越多个AS（Autonomous System，自治系统）时，需要连通其分布在不同AS内的Site，这种VPN跨越多个AS的应用方式被称为跨域VPN。跨域VPN的解决方案包括（详细介绍请参见“MPLS配置指导”中的“MPLS L3VPN”）：
· ASBR之间建立VRF-to-VRF连接，也称为A类跨AS。
· ASBR之间通过MP-EBGP发布VPN-IPv4路由，也称为B类跨AS。
· PE之间通过MP-EBGP发布VPN-IPv4路由，也称为C类跨AS。
如图1-10所示，VPN跨越了AS 100和AS 200两个自治系统，PE 3和PE 4分别是AS 100和AS 200的ASBR。PE 3和PE 4通过各自的VPN实例相连，并互把对方视为CE设备。
图1-10 A类跨AS的BIER模式MVPN示意图
采用本方式时，需在每个AS内各建立一个独立的MVPN，在各MVPN之间实现私网组播数据跨AS的传输。跨AS传输私网组播数据的过程如下：
(1) 由于PE 3与PE 4互把对方视为自己的CE，因此：在AS 100中，CE 1与PE 4（相当于PE 3的CE）之间可以互通组播业务；在AS 200中，CE 2与PE 3（相当于PE 4的CE）之间也可以互通组播业务。
(2) CE 1发出VPN 1的私网组播协议和数据报文在PE 1上经过MPLS封装后通过BIER Tunnel1到达PE 3，PE 3解封装后通过普通三层组播转发到达PE 4，该报文被PE 4视为与自己私网接口相连的VPN 2的私网报文，于是将其通过BIER Tunnel2转发给CE 2；CE 2发出的VPN 2的报文也同理到达CE 1。这样，就实现了私网组播数据在CE 1与CE 2之间的互通。
A类跨域域间无法互相学习通告激活组播源的自动发现路由（Source Active A-D route），所以必须在RP间配置MSDP或anycast-RP用于域间传递组播源信息。
当前仅G-BIER与MSR6支持C类跨AS的BIER模式MVPN。
如图1-11所示，VPN跨越了AS 100和AS 200两个自治系统，PE 3和PE 4分别是AS 100和AS 200的ASBR。PE 3和PE 4通过MP-EBGP相连，并互把对方视为P设备。在此组网中，不同AS的PE之间建立多跳MP-EBGP会话，并通过该会话直接在PE之间发布VPN-IPv4路由。
图1-11 C类跨AS的BIER模式MVPN示意图
采用本方式时，只需在所有AS内统一建立一个MVPN即可，在该MVPN内实现私网组播数据跨AS的传输。跨AS传输私网组播数据的过程如下：
(1) CE 1收到组播流量后，如果域内RP为PE 1，则发送注册报文到PE 1；如果RP为CE 1或者CE 2，需要通过建立MSDP或者Anycast-RP将组播源信息发送到PE 1。不管哪种方式，当PE 1发现组播源信息后，发送source-active A-D route通告组播源，该路由可以通过BGP直接发送给PE 2。
(2) PE 2上收到source-active A-D route后，检查本AS域内是否存在组播接收者信息，如果存在接收者，向上游发送C-Multicast Route加入，该路由可以通过BGP直接传递到PE 1。
(3) PE 1收到C-Multicast Route后，将组播流量封装MPLS标签后通过BIER Tunnel发送到PE 2，在PE 2上进行解封装后转发到私网侧。

执行本配置后，本设备向发送给对等体的BGP路由增加Source AS Extended Community、VRF Route Import Extended Community和IDF Negotiation Community属性：
· Source AS Extended Community属性携带本地BGP自治系统号信息，取值为MVPN组播源的AS号，格式为32位自治系统号:0，例如：100:0。
· VRF Route Import Extended Community属性携带本地源地址标识和BGP 路由所属的VPN实例信息，格式为32位或128位源地址标识:VPN实例索引，例如：192.168.122.15:1。
· IDF Negotiation Community属性为IDF协商属性，如果建立起BGP会话的对等体双方都收到了来自对方的携带IDF Negotiation Community属性的路由，则这两台设备开始协商选举出主用IDF和备用IDF。IDF Negotiation Community属性的取值为0x0000ffff。需要注意的是，只有通过warm-root-standby命令开启了组播温备功能时，设备才能为路由添加IDF Negotiation Community属性，否则只能为路由添加Source AS Extended Community和VRF Route Import Extended Community属性。
在组播VPN网络中，组播源侧PE需要向其他PE发布本地产生的Source AS Extended Community、VRF Route Import Extended Community和IDF Negotiation Community属性，发布方式为将这些属性携带在来自私网CE的路由中，发布给骨干公网中的其他PE，以协助组播表项顺利建立以及IDF的选举。但当PE创建的MVPN属于公网实例时，PE和CE都位于公网，组播源侧PE无法自动区分要为哪些路由携带Source AS Extended Community、VRF Route Import Extended Community和IDF Negotiation Community属性。
因此，需要通过本功能在组播源侧PE上手动指定CE，以帮助组播源侧PE识别需要为哪些路由携带Source AS Extended Community、VRF Route Import Extended Community和IDF Negotiation Community属性的路由。
在纯公网场景中，执行peer mvpn-rt-import命令和mvpn-advertise-rt-import命令后，设备将为从指定对等体/对等体组接收到的BGP路由添加Source AS Extended Community、VRF Route Import Extended Community和IDF Negotiation Community属性。并且设备可以将添加属性后的路由发布给对等体。
· 组播源和组播接收者位于公网时，如果MVPN支持IPv6 Underlay功能处于开启状态，请在BGP IPv6单播地址族视图或BGP IPv6组播地址族视图下配置本功能；如果MVPN支持IPv6 Underlay功能处于关闭状态，请在BGP IPv4单播地址族视图或BGP IPv4组播地址族视图下配置本功能。
· 组播源和组播接收者位于私网时，请在BGP VPNv4地址族视图、BGP VPNv6地址族视图或BGP EVPN地址族视图下配置本功能。
· 在BGP IPv4单播地址族视图和BGP IPv4组播地址族视图下配置本功能的效果一致，在BGP IPv6单播地址族视图和BGP IPv6组播地址族视图下配置本功能的效果一致。
· 建立了BGP IPv4 MVPN对等体后，BGP IPv4单播地址族视图、BGP IPv4组播地址族视图以及BGP VPNv4地址族视图下配置的本功能才能生效。
· 建立了BGP IPv6 MVPN对等体后，BGP IPv6单播地址族视图、BGP IPv6组播地址族视图以及BGP VPNv6地址族视图下配置的本功能才能生效。
· 在BGP IPv4单播地址族视图、BGP IPv4组播地址族视图、BGP IPv6单播地址族视图以及BGP IPv6组播地址族视图下配置本命令后，发布的BGP路由中携带的VPN实例索引为0。若通过source命令配置了MVPN源接口，则源地址使用MPVN源接口地址，否则使用本地BGP实例的Router ID。这两个属性用来标识生成这条路由的设备。
· 执行peer mvpn-rt-import命令后，如果设备从指定对等体/对等体组收到的路由中，原本就携带了Source AS Extended Community、VRF Route Import Extended Community和IDF Negotiation Community属性，则设备不会为路由重复添加这三个属性，也不会修改这三个属性。
· 执行undo peer mvpn-rt-import命令后，设备不会再为从指定对等体/对等体组收到的路由添加Source AS Extended Community、VRF Route Import Extended Community和IDF Negotiation Community属性，并且会删除本地已经为路由添加的这些属性。

目前，IANA为IPv6地址类型的VRF Route Import Extended Community和Route Target扩展团体属性规定的类型值分别为0x000b和0x0002，H3C设备按照该标准为BGP路由携带扩展团体属性。一些厂商对VRF Route Import Extended Community和Route Target扩展团体属性的发送、识别类型值定义为0x010b和0x0102，无法与H3C设备互通。
开启IPv6地址类型的扩展团体属性兼容功能后，BGP将修改发送路由携带的VRF Route Import Extended Community和Route Target扩展团体属性的类型值，将其修改为0x010b和0x0102；BGP还会将修改接收路由携带的VRF Route Import Extended Community和Route Target扩展团体属性的类型值，将其修改为0x000b和0x0002，以实现同其他厂商设备的互通。

组播源侧PE可以在1类路由（Intra-AS I-PMSI A-D route）和3类路由（S-PMSI A-D route）中携带SID，该SID即为隧道源地址，可用于BIERv6或MSR6封装类型的BIER模式MVPN。
接收者侧PE收到1类和3类路由后，根据路由携带的Route Targe属性匹配本地的VPN实例或公网实例，并记录路由携带的SID与VPN实例或公网实例的对应关系。接收侧PE收到BIERv6或MSR6封装的组播报文时，会根据报文中的BIERv6或MSR6隧道源地址找到对应的VPN实例或公网实例，在VPN实例或公网实例对应的MVPN实例中建立组播转发表项，并转发组播报文。

在组播VPN中，当组播源侧PE发生故障时，用户组播业务将出现中断。只有在单播路由收敛后，组播业务才能恢复。但是，单播路由收敛时间长，远远不能满足实时性要求高的组播业务的需求。组播FRR功能可以用来解决上述问题。
组播源通过两个PE（PE 1和PE 2）接入公网，分别形成以PE 1和PE 2为根、接收者侧PE为叶子的两条BIER隧道。接收者侧PE根据路由优选策略选择主备隧道。在链路正常的情况下，组播数据流量沿主备隧道同时转发。接收者侧PE会选择接收主隧道的组播数据流量，丢弃备隧道的组播数据流量。在接收者侧PE上配置组播FRR功能后，接收者侧PE将为同一个（S，G）表项保存主备两个入接口，并周期性检测主备入接口的组播流量。如果检测到组播流量未从主入接口到达，则表示主隧道存在故障，此时接收者侧PE将选择接收从备份隧道发来的组播流量，从而大幅提高组播业务收敛速度，提高可靠性。
本功能可以在MVPN地址族视图下或BGP地址族视图下配置。如果组播源以及接收者位于公网，请在BGP地址族视图下配置本功能；如果组播源以及接收者位于私网，请在MVPN地址族视图下配置本功能。

在组播VPN中，当组播源侧PE发生故障时，组播业务将出现中断。只有在单播路由收敛后，组播业务才能恢复。但是，单播路由收敛时间长，远远不能满足实时性要求高的组播业务的需求。
在组网中部署两台组播源侧PE，并通过本命令在两台组播源侧PE及对应接收者侧PE上开启组播温备功能可以解决上述问题。
如图1-12所示，组播源通过两个PE（PE 1和PE 2）接入公网，接收者侧PE同时向PE 1和PE 2发送组播加入请求，分别形成以PE 1和PE 2为根、接收者侧PE（PE 3）为叶子的两条BIER隧道。
在任一时刻仅有一个组播源侧PE负责向接收者侧PE发送组播流量。在链路正常的情况下，负责向接收者侧发送组播流量的组播源侧PE称为主用IDF（Ingress Designated Forwarder，入口指定转发器），另一组播源侧PE设备称为备用IDF。当主用IDF故障之后，备用IDF接替主用IDF角色负责向接收者侧PE发送组播流量。
· 仅BIER模式的组播VPN支持本命令。
· 组播温备功能和FRR功能互斥，同一MVPN不能同时配置。
· 组播温备功能和组播流量负载分担功能互斥，同一MVPN不能同时配置。关于组播流量负载分担功能的详细介绍，请参见“IP组播命令参考”中的load-splitting命令。
· 由于温备功能通过周期性检测流量的方式判断链路故障，此功能仅适用于持续、大速率转发组播流量的场景。否则可能会因为没有检测到流量，导致备用IDF无法接替主用IDF转发流量。

IDF选举规则分为两类：
· 基于MVPN实例选择主用IDF：系统将选择源地址更小的BIER隧道作为主用隧道，即选择该隧道的根为主用IDF。
· 基于（S，G）表项选择主用IDF：系统将通过特定哈希函数，对BIER隧道源地址、组播源的地址S、组播组的地址G进行哈希计算，并选择哈希计算结果更小的BIER隧道作为主用隧道，即选择该隧道的根为主用IDF。
· 在配置本功能前，请先通过warm-root-standby命令开启组播温备功能。
· 可通过以下命令配置BIER隧道的源地址：
¡ G-BIER隧道头端节点的组播服务源地址：tunnel-source
¡ IPv4组播VPN中BIERv6或MSR6隧道的源地址：src-dt4 locator

|
功能描述 |
· 组播源侧PE实现组播温备功能：当主用IDF故障之后，备用IDF接替主用IDF角色负责向接收者侧PE发送组播流量 · 公网配置本地保护：当公网的中间节点或主路径故障时，数据流量在其他设备单播路由收敛之前，快速切换到备份路径继续转发 |
|
组播源和接收者 |
VPN实例a中的组播源为S，接收者为R |
|
PE各接口所属实例 |
· PE 1：Ten-GigabitEthernet3/1/1和LoopBack1接口属于VPN实例a，Ten-GigabitEthernet3/1/3、Ten-GigabitEthernet3/1/4和LoopBack0接口属于公网实例 · PE 2：Ten-GigabitEthernet3/1/4接口属于VPN实例a，Ten-GigabitEthernet3/1/2、Ten-GigabitEthernet3/1/3和LoopBack0接口属于公网实例 · PE 3：Ten-GigabitEthernet3/1/2接口属于VPN实例a，Ten-GigabitEthernet3/1/3、Ten-GigabitEthernet3/1/1和LoopBack0接口属于公网实例 · PE 4：Ten-GigabitEthernet3/1/2接口属于VPN实例a，Ten-GigabitEthernet3/1/3、Ten-GigabitEthernet3/1/1和LoopBack0接口属于公网实例 |
|
单播路由协议和BIER |
· 在公网中配置IS-IS，在各PSR与SW之间配置EBGP对等体 · 在PE 1、PE 2和PE 3、PE 4各自的LoopBack0接口两两之间建立IBGP对等体 · 在公网中配置BIER子域0、BSL为128、Max-SI为32 · 在PE 1、PE 2、P 1、P 2、P 3、P 4和PE 3、PE 4上配置BFR prefix为各自LoopBack0接口的IPv6地址，并各自配置End.RGB SID |
|
IP组播路由功能 |
· 在PE 1、PE 2和PE 3、PE 4的VPN实例a中均使能IP组播路由 · 在CE 1和CE 2上均使能IP组播路由 |
|
IGMP功能 |
在PE 3和PE 4的Ten-GigabitEthernet3/1/2接口上使能IGMPv3 |
|
PIM功能 |
私网中运行PIM-SM： · 在PE 1、PE 2和PE 3、PE 4的所有不与接收者直连的私网接口上均使能PIM-SM · 在CE 1和CE 2所有不连接接收者的接口上均使能PIM-SM · PE 1和PE 2的LoopBack1接口为VPN a的C-BSR和C-RP（服务于所有组播组） |

组网需求如表1-13所示。
表1-13 跨AS域 BIER温备本地保护配置（MSR6封装类型）组网需求
|
项目 |
组网需求 |
|
功能描述 |
· 组播源侧PE实现组播温备功能：当主用IDF故障之后，备用IDF接替主用IDF角色负责向接收者侧PE发送组播流量 · 公网配置本地保护：当公网的中间节点或主路径故障时，数据流量在其他设备单播路由收敛之前，快速切换到备份路径继续转发 |
|
组播源和接收者 |
VPN实例a中的组播源为S，接收者为R |
|
PE各接口所属实例 |
· PE 1：Ten-GigabitEthernet3/1/1和LoopBack1接口属于VPN实例a，Ten-GigabitEthernet3/1/3、Ten-GigabitEthernet3/1/4和LoopBack0接口属于公网实例 · PE 2：Ten-GigabitEthernet3/1/4接口属于VPN实例a，Ten-GigabitEthernet3/1/2、Ten-GigabitEthernet3/1/3和LoopBack0接口属于公网实例 · PE 3：Ten-GigabitEthernet3/1/2接口属于VPN实例a，Ten-GigabitEthernet3/1/3、Ten-GigabitEthernet3/1/1和LoopBack0接口属于公网实例 · PE 4：Ten-GigabitEthernet3/1/2接口属于VPN实例a，Ten-GigabitEthernet3/1/3、Ten-GigabitEthernet3/1/1和LoopBack0接口属于公网实例 |
|
单播路由协议和BIER |
· 在公网AS 100和AS 200中配置IS-IS，在P 1与P 3、P 2与P 4之间配置EBGP对等体 · 在PE 1与PE 2、PE 3、PE 4的LoopBack0接口之间建立BGP对等体 · 在PE 2与PE 1、PE 3、PE 4的LoopBack0接口之间建立BGP对等体 · 在PE 3 与PE 1、PE 2、PE 4的LoopBack0接口之间建立BGP对等体 · 在PE 4 与PE 1、PE 2、PE 3的LoopBack0接口之间建立BGP对等体 · 在公网中配置BIER子域0、BSL为128、Max-SI为32 · 在PE 1、PE 2、P 1、P 2、P 3、P 4和PE 3、PE 4上配置BFR prefix为各自LoopBack0接口的IPv6地址，并各自配置End.RGB SID |
|
IP组播路由功能 |
· 在PE 1、PE 2和PE 3、PE 4的VPN实例a中均使能IP组播路由 · 在CE 1和CE 2上均使能IP组播路由 |
|
IGMP功能 |
在PE 3和PE 4的Ten-GigabitEthernet3/1/2接口上使能IGMPv2 |
|
PIM功能 |
私网中运行PIM-SM： · 在PE 1、PE 2和PE 3、PE 4的所有不与接收者直连的私网接口上均使能PIM-SM · 在CE 1和CE 2所有不连接接收者的接口上均使能PIM-SM · PE 1和PE 2的LoopBack1接口为VPN a的C-BSR和C-RP（服务于所有组播组） |

组网需求如表1-15所示。
表1-15 跨AS域BIER前缀保留IBGP(Proxy)-EBGP-ISIS（MSR6封装类型）组网需求
|
项目 |
组网需求 |
|
功能描述 |
· 对于MSR6封装类型，ASBR设备对域外的BIER前缀信息进行保留，域内进行域外信息发布的时候，使用原有前缀信息发布 · AS 100内通过BGP报文携带BIER信息，AS 200通过IS-IS报文携带BIER信息 |
|
组播源和接收者 |
VPN实例a中的组播源为S，接收者为R |
|
PE各接口所属实例 |
· PE 1：Ten-GigabitEthernet3/1/2和LoopBack1接口属于VPN实例a，Ten-GigabitEthernet3/1/1和LoopBack0接口属于公网实例 · PE 2：Ten-GigabitEthernet3/1/2接口属于VPN实例a，Ten-GigabitEthernet3/1/1和LoopBack0接口属于公网实例 |
|
单播路由协议和BIER |
· 在公网AS 100中配置IBGP，在AS 200中配置IS-IS，在ASBR 1与ASBR 2之间配置EBGP对等体 · 在PE 1与P 1、P 1与ASBR 1和PE 1与ASBR 1的LoopBack0接口之间建立BGP对等体 · 在ASBR 2 与PE 2的LoopBack0接口之间建立BGP对等体 · 在PE 1与PE 2的LoopBack0接口之间建立BGP对等体 · 在公网中配置BIER子域0、BSL为128、Max-SI为32 · 在PE 1、ASBR 1、ASBR 2、PE 2上配置BFR prefix为各自LoopBack0接口的IPv6地址，并各自配置End.RGB SID |
|
IP组播路由功能 |
在PE 1和PE 2的VPN实例a中均使能IP组播路由 |
|
IGMP功能 |
PE 2的Ten-GigabitEthernet3/1/2接口上使能IGMP |
|
PIM功能 |
私网中运行PIM-SM： · 在PE 1和PE 2的所有不与接收者直连的私网接口上均使能PIM-SM · PE1的LoopBack1接口为VPN a的C-BSR和C-RP（服务于所有组播组） |

|
项目 |
组网需求 |
|
功能描述 |
· 对于MSR6封装类型，ASBR设备对域外的BIER前缀信息进行保留，域内进行域外信息发布的时候，使用原有前缀信息发布 · AS 100内通过BGP报文携带BIER信息，AS 200通过BGP报文携带BIER信息 |
|
组播源和接收者 |
VPN实例a中的组播源为S，接收者为R |
|
PE各接口所属实例 |
· PE 1：Ten-GigabitEthernet3/1/2和LoopBack1接口属于VPN实例a，Ten-GigabitEthernet3/1/1和LoopBack0接口属于公网实例 · PE 2：Ten-GigabitEthernet3/1/2接口属于VPN实例a，Ten-GigabitEthernet3/1/1和LoopBack0接口属于公网实例 |
|
单播路由协议和BIER |
· 在公网AS 100和 AS 200中均配置IBGP，在ASBR 1与ASBR 2之间配置EBGP对等体 · 在PE 1与P 1、P 1与ASBR 1和PE 1与ASBR 1的LoopBack0接口之间建立BGP对等体 · 在PE 2与P 2、P 2与ASBR 2和PE 2与ASBR 2的LoopBack0接口之间建立BGP对等体 · 在PE 1 与PE 2的LoopBack0接口之间建立BGP对等体 · 在公网中配置BIER子域0、BSL为128、Max-SI为32 · 在PE 1、ASBR 1、ASBR 2、PE 2上配置BFR prefix为各自LoopBack0接口的IPv6地址，并各自配置End.RGB SID |
|
IP组播路由功能 |
在PE 1和PE 2的VPN实例a中均使能IP组播路由 |
|
IGMP功能 |
PE 2的Ten-GigabitEthernet3/1/2接口上使能IGMP |
|
PIM功能 |
私网中运行PIM-SM： · 在PE 1和PE 2的所有不与接收者直连的私网接口上均使能PIM-SM · PE1的LoopBack1接口为VPN a的C-BSR和C-RP（服务于所有组播组） |

项目 |
组网需求 |
|
功能描述 |
· 对于MSR6封装类型，ASBR设备对域外的BIER前缀信息进行保留，域内进行域外信息发布的时候，使用原有前缀信息发布 · AS 100内通过BGP或IS-IS报文携带BIER信息，AS 200通过IS-IS报文携带BIER信息 |
|
组播源和接收者 |
VPN实例a中的组播源为S，接收者为R |
|
PE各接口所属实例 |
· PE 1：Ten-GigabitEthernet3/1/2和LoopBack1接口属于VPN实例a，Ten-GigabitEthernet3/1/1和LoopBack0接口属于公网实例 · PE 2：Ten-GigabitEthernet3/1/2接口属于VPN实例a，Ten-GigabitEthernet3/1/1和LoopBack0接口属于公网实例 |
|
单播路由协议和BIER |
· 在公网AS 100和AS 200中配置IS-IS，在ASBR 1与ASBR 2之间配置EBGP对等体 · 在PE 1与ASBR 1的LoopBack0接口之间建立BGP对等体 · 在ASBR 2 与PE 2的LoopBack0接口之间建立BGP对等体 · 在PE 1与PE 2的LoopBack0接口之间建立BGP对等体 · 在公网中配置BIER子域0、BSL为128、Max-SI为32 · 在PE 1、ASBR 1、ASBR 2、PE 2上配置BFR prefix为各自LoopBack0接口的IPv6地址，并各自配置End.RGB SID |
|
IP组播路由功能 |
在PE 1和PE 2的VPN实例a中均使能IP组播路由 |
|
IGMP功能 |
PE 2的Ten-GigabitEthernet3/1/2接口上使能IGMP |
|
PIM功能 |
私网中运行PIM-SM： · 在PE 1和PE 2的所有不与接收者直连的私网接口上均使能PIM-SM · PE 1的LoopBack1接口为VPN a的C-BSR和C-RP（服务于所有组播组） |

|
项目 |
组网需求 |
|
功能描述 |
· 对于G-BIER封装类型，ASBR设备对域外的BIER前缀信息进行替换，不保留原有前缀，域内进行域外信息发布的时候，使用ASBR的前缀信息发布 · AS 100内通过IS-IS报文携带BIER信息，AS 200通过IS-IS报文携带BIER信息 |
|
组播源和接收者 |
VPN实例a中的组播源为S，接收者为R |
|
PE各接口所属实例 |
· PE 1：Ten-GigabitEthernet3/1/2和LoopBack1接口属于VPN实例a，Ten-GigabitEthernet3/1/1和LoopBack0接口属于公网实例 · PE 2：Ten-GigabitEthernet3/1/2接口属于VPN实例a，Ten-GigabitEthernet3/1/1和LoopBack0接口属于公网实例 |
|
单播路由协议和BIER |
· 在公网AS 100和AS 200中配置IS-IS，在ASBR 1与ASBR 2之间配置EBGP对等体 · 在PE 1与ASBR 1的LoopBack0接口之间建立BGP对等体 · 在ASBR 2 与PE 2的LoopBack0接口之间建立BGP对等体 · 在PE 1与PE 2的LoopBack0接口之间建立BGP对等体 · 在公网中配置BIER子域0、BSL为128、Max-SI为32 · 在PE 1、ASBR 1、ASBR 2、PE 2上配置BFR prefix为各自LoopBack0接口的IPv6地址，并各自配置组播策略预留地址 |
|
IP组播路由功能 |
在PE 1和PE 2的VPN实例a中均使能IP组播路由 |
|
IGMP功能 |
PE 2的Ten-GigabitEthernet3/1/2接口上使能IGMP |
|
PIM功能 |
私网中运行PIM-SM： · 在PE 1和PE 2的所有不与接收者直连的私网接口上均使能PIM-SM · PE 1的LoopBack1接口为VPN a的C-BSR和C-RP（服务于所有组播组） |

|
功能描述 |
· 对于G-BIER封装类型，ASBR设备对域外的BIER前缀信息进行替换，不保留原有前缀，域内进行域外信息发布的时候，使用ASBR的前缀信息发布 · AS 100内通过BGP报文携带BIER信息，AS 200通过IS-IS报文携带BIER信息 |
|
组播源和接收者 |
VPN实例a中的组播源为S，接收者为R |
|
PE各接口所属实例 |
· PE 1：Ten-GigabitEthernet3/1/2和LoopBack1接口属于VPN实例a，Ten-GigabitEthernet3/1/1和LoopBack0接口属于公网实例 · PE 2：Ten-GigabitEthernet3/1/2接口属于VPN实例a，Ten-GigabitEthernet3/1/1和LoopBack0接口属于公网实例 |
|
单播路由协议和BIER |
· 在公网AS 100中配置IBGP，在AS 200中配置IS-IS，在ASBR 1与ASBR 2之间配置EBGP对等体 · 在PE 1与P 1、P 1与ASBR 1和PE 1与ASBR 1的LoopBack0接口之间建立BGP对等体 · 在ASBR 2与PE 2的LoopBack0接口之间建立BGP对等体 · 在PE 1与PE 2的LoopBack0接口之间建立BGP对等体 · 在公网中配置BIER子域0、BSL为128、Max-SI为32 · 在PE 1、ASBR 1、ASBR 2、PE 2上配置BFR prefix为各自LoopBack0接口的IPv6地址，并各自配置组播策略预留地址 |
|
IP组播路由功能 |
在PE 1和PE 2的VPN实例a中均使能IP组播路由 |
|
IGMP功能 |
在PE 1的Ten-GigabitEthernet3/1/2和PE 2的 Ten-GigabitEthernet3/1/2接口上使能IGMP |
|
PIM功能 |
私网中运行PIM-SM： · 在PE 1和PE 2的所有不与接收者直连的私网接口上均使能PIM-SM · PE 1的LoopBack1接口为VPN a的C-BSR和C-RP（服务于所有组播组） |

|
项目 |
组网需求 |
|
功能描述 |
· 对于G-BIER封装类型，ASBR设备对域外的BIER前缀信息进行替换，不保留原有前缀，域内进行域外信息发布的时候，使用ASBR的前缀信息发布 · AS 100内通过BGP报文携带BIER信息，AS 200通过BGP报文携带BIER信息 |
|
组播源和接收者 |
VPN实例a中的组播源为S，接收者为R |
|
PE各接口所属实例 |
· PE 1：Ten-GigabitEthernet3/1/2和LoopBack1接口属于VPN实例a，Ten-GigabitEthernet3/1/1和LoopBack0接口属于公网实例 · PE 2：Ten-GigabitEthernet3/1/2接口属于VPN实例a，Ten-GigabitEthernet3/1/1和LoopBack0接口属于公网实例 |
|
单播路由协议和BIER |
· 在公网AS 100和 AS 200中均配置IBGP，在ASBR 1与ASBR 2之间配置EBGP对等体 · 在PE 1与P 1、P 1与ASBR 1和PE 1与ASBR 1的LoopBack0接口之间建立BGP对等体 · 在PE 2与P 2、P 2与ASBR 2和PE 2与ASBR 2的LoopBack0接口之间建立BGP对等体 · 在PE 1 与PE 2的LoopBack0接口之间建立BGP对等体 · 在公网中配置BIER子域0、BSL为128、Max-SI为32 · 在PE 1、ASBR 1、ASBR 2、PE 2上配置BFR prefix为各自LoopBack0接口的IPv6地址，并各自配置组播策略预留地址 |
|
IP组播路由功能 |
在PE 1和PE 2的VPN实例a中均使能IP组播路由 |
|
IGMP功能 |
PE 2的Ten-GigabitEthernet3/1/2接口上使能IGMP |
|
PIM功能 |
私网中运行PIM-SM： · 在PE 1和PE 2的所有不与接收者直连的私网接口上均使能PIM-SM · PE 1的LoopBack1接口为VPN a的C-BSR和C-RP（服务于所有组播组） |
