案例分析：ACI交换矩阵中的L3组播
简介
从版本2.0开始，ACI交换矩阵支持第3层组播路由，并且需要EX交换机（即N9K-C93180YC-EX）。 在版本2.0之前，ACI仅支持网桥域内的L2组播。 在2.0中这仍是一个有效的选项，可用于非EX交换机。
在ACI版本2.0中，支持的组播路由功能包括：PIM ASM、PIM SSM、静态RP、PIM自动RP和PIM BSR。
在本文档中，我们介绍一个经验证的解决方案，用于在ACI交换矩阵上进行L3组播路由的实际客户部署方案。所选ACI版本为2.1(1h)。 此版本不支持交换矩阵上的RP，因此PIM ASM需要外部RP。
设计要求
客户需要在交换矩阵内外使用L3组播路由的端到端解决方案。部署方案具有以下要求：
- 为所有租户部署一个VRF。
注意：组播需要每个VRF使用专用L3out。如果交换矩阵中有多个VRF，则组播路由不支持共享L3out。
- 带有外部源的交换矩阵中的接收器
- 带有外部接收器的交换矩阵中的源
- 交换矩阵中的源和接收器
- 静态RP或自动RP
解决方案
拓扑审核
在拓扑中，有两个主要组件：aci模块和分层LAN网络模块。两个模块通过运行OSPF和PIM的点对点L3链路连接到核心设备。在ACI模块中，外部路由网络称为与VRF common:default关联的L3out-to-Core。它包括从两个边界枝叶到核心设备的四个链路。分层局域网网络模块（称为交换矩阵外部）由传统接入层和带vPC的汇聚层组成。
第3层组播流通过核心层在ACI交换矩阵和传统LAN网络上运行。对于静态RP方案，RP部署在广域网边缘设备上。
我们使用Spirent流量生成器(STC)来模拟内部和外部源和接收器。Spirent端口连接到ACI模块和分层局域网网络模块中的不同位置。接收方发送IGMP v2成员资格加入消息。
连接到Sleaf2的内部源：源IP地址为10.101.101.115~124，发送到组地址：228.0.0.1~10
连接到Bleaf1、Cleaf1和Cleaf2的内部接收器：支持组播的BD是BD90、BD91、BD31、BD32，感兴趣的组：228.0.0.1~10和229.0.0.1~10。
连接到LAN网络中接入层的外部源：源IP地址为10.103.103.40~49，发送到组地址：229.0.0.1~10。
连接到LAN网络接入层的外部接收器：vlan131、vlan132，感兴趣的组：228.0.0.1~10。
配置
第 0 步： 在连接到核心的模拟广域网设备上设置RP，在分层局域网网络设备上启用PIM稀疏模式。
!!!!! RP configuration ip pim rp-address 99.99.99.99 group-list 224.0.0.0/4 ip pim ssm range 232.0.0.0/8 interface loopback99 ip address 99.99.99.99/32 ip router ospf 65017 area 0.0.0.0 ip pim sparse-mode interface Ethernet2/1 ip pim sparse-mode interface Ethernet2/2 ip pim sparse-mode
第1步：在VRF上启用组播。在租户空间中，导航到网络> VRF >组播，在工作面板上，点击黄油以启用组播。
第2步：在BD和L3out级别启用组播，为接收方BD启用IGMP。导航到Networking > VRFs > VRF name > Multicast，在工作面板上，选择Configuration > Interface选项卡，点击“+”以添加需要组播流量的网桥域。为启用组播的BD启用IMGP策略。
然后单击“+”为此VRF添加L3out。当为L3out启用组播时，它将启用L3out下所有接口上的PIM，并且该L3out的所有边界枝叶均通过组播路由启用。为L3out接口组选择PIM策略。
此处假设BD和L3out已调配。
将IGMP策略附加到BD使其也成为IGMP查询器。IGMP策略在Tenant > Networking > Protocol Policies > IGMP Interface下配置。默认IGMP策略具有以下参数，您可以在其中定义查询间隔。如果未指定策略，接口将使用默认策略。
PIM策略也在Tenant > Networking > Protocol Policies > PIM下配置。
默认PIM策略具有以下参数，您可以在其中定义hello间隔。
边界枝叶上的L3Outs必须配置为在节点配置文件中启用环回地址。
步骤 3：为PIM ASM配置RP。导航到Tenant > VRF > Multicast，在工作面板中选择Configuration > Rendezvous Points。在本示例中，选择静态RP。点击“+”以添加RP。
对于自动RP配置，请选中“交汇点”(Rendezvous Points)页面上的“转发自动RP更新”(Forward Auto-RP updates)和“侦听自动RP更新”(Listen Auto-RP Updates)复选框。
在ACI交换矩阵之外，NX-OS平台上的自动RP配置保持不变。
!!! On RP candidate ip pim send-rp-announce loopback99 group-list 224.0.0.0/4 ip pim send-rp-discovery loopback99 scope 32 !!! On RP listeners: ip pim auto-rp listen forward
第4步：配置必要的PIM设置。导航到Tenant >VRF -> Multicast，在工作面板中选择Configuration > PIM settings，注意由APIC从组播组地址池分配的VRF GIPo地址225.1.192.0/32。对于启用PIM的BD，VRF GIPo将用作组播流量的外部组IP地址。
当启用快速收敛模式（默认情况下为禁用）时，所有启用了PIM的边界枝叶都将向外部网络发送联合，但只有一个边界枝叶会将流量转发到交换矩阵以防止重复。转发组流量的边界枝叶是组的指定转发器。当由于边界枝叶关闭而出现条带优胜者更改时，启用快速收敛有助于缩短具有外部源和内部接收器的组播流的数据包丢弃持续时间。从新的条带优胜者加入PIM树不会产生延迟。由于所有边界都从外部源提取流量，因此要付出对非条带优胜者的外部链路增加带宽使用量的代价。
About the Stripe Winner — 当前ACI使用BSR（Bootstrap路由器）哈希计算BL条带赢家。 使用枝叶的S、G和环回IP计算散列。 从ACI 3.0(1)开始，无法影响用户的条带获胜者选举。
第5步：创建所需的合同以允许组播流量：
— 交换矩阵内的源和接收器（无需合同）
— 接收器在交换矩阵内，外部源（不需要合同）
— 源内部交换矩阵、外部接收器（需要合同）*
*如果BD部署在边界枝叶上，则不需要合同
在本例中，我们在交换矩阵外具有接收器，应用L3out_to_Core与EPG101中组播源之间的合同。
验证
PIM验证
为组播路由启用VRF时，交换矩阵内为组播路由创建交换矩阵接口（隧道）。PIM控制平面数据包通过交换矩阵内的交换矩阵接口发送。隧道目标将是VRF GiPo组播地址。在边界枝叶交换机上，隧道源将是边界枝叶上的环回接口。在非边界枝叶交换机上，隧道源将是环回地址(127.0.0.100)。
边界枝叶在交换矩阵接口上发送PIM问询。L3Out接口在正常模式下运行PIM，包括发送和接收hello、选择DR等。非边界枝叶在交换矩阵接口上以被动模式运行；它们会侦听来自边界枝叶的PIM hello，但不会发送PIM hello。无边界枝叶不会显示在“show ip pim neighbor”的输出中。

活动边界枝叶验证
如果通过组播路由启用多个边界枝叶，APIC会为所有活动边界枝叶上的每个组地址选择一个条带胜者。作为组条带优胜者的边界枝叶负责代表交换矩阵发送PIM加入并将组播流量转发到交换矩阵。
组条带化优胜者将决定指定转发器。如果条带优胜者能够到达根节点，则条带优胜者也是DF。如果条带优胜者没有到根的外部连接，则该BL通过在交换矩阵接口上发送PIM加入来选择DF。
