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，此选项仍然有效，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，我们将介绍适用于ACI交换矩阵上L3组播路由的实际客户部署方案的经验证的解决方案。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
客户需要端到端解决方案来实现交换矩阵内外的第3层组播路由。部署方案具有以下要求：
- 为所有租户部署一个VRF。
注意：组播要求每个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。
- 交换矩阵中具有外部源的接收器
- 具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
拓扑回顾
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条链路。分层LAN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。
L3组播流通过核心层在ACI交换矩阵和传统LAN网络中运行。对于静态RP场景，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LAN网络模块中的不同位置。接收方发送IGMP v2成员加入消息。
连接到Sleaf2的内部源：源IP地址为10.101.101.115~124，正在发送到组地址：228.0.0.1~10
连接到Bleaf1、Cleaf1和Cleaf2的内部接收器：启用组播的BD为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WAN设备上设置RP，在分层LAN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> VRFs>组播，在工作面板上，单击黄油以启用组播。
第2步：在BD和L3out级别启用组播，为接收方BD启用IGMP。导航至Networking > VRFs > VRF name > Multicast，在工作面板上，选择Configuration > Interface选项卡，单击“+”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，它将在L3out下的所有接口上启用PIM，并且该L3out的所有边界枝叶都通过组播路由启用。为L3out接口组选择PIM策略。
此处假设已调配BD和L3out。
将IGMP策略附加到BD也使其成为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L3Out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。导航至Tenant > VRF > Multicast，在工作面板中选择Configuration > Rendezvous Points。在本例中，选择了静态RP。单击“+”添加RP。
对于自动RP配置，选中“Rendezvous Points”（交汇点）页面上的“Forward Auto-RP updates”（转发自动RP更新）和“Listen to Auto-RP Updates”（侦听自动RP更新）复选框。
在ACI交换矩阵外，NX-OS平台上的AUTO-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。导航至租户>VRF ->组播，在工作面板中，选择配置> PIM设置，注意VRF GIPo地址225.1.192.0/32，由APIC从组播组地址池分配。VRF GIPo将用作启用PIM的BD的组播流量的外部组IP地址。
启用快速融合模式（默认为禁用）后，启用PIM的所有边界枝叶将向外部网络发送加入，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。启用快速融合有助于在边界枝叶关闭导致条带赢家更改时，减少具有外部源和内部接收器的组播流的丢包持续时间。从新条带赢家加入PIM树不会产生延迟。这是以非条带赢家的外部链路上额外带宽使用的成本计算的，因为所有边框都会从外部源中拉出流量。
关于条带优胜者 — 当前ACI使用BSR（引导路由器）哈希计算BL条带优胜者。 散列值使用枝叶的S、G和环回IP计算。 自ACI 3.0(1)起，无法影响用户的条带赢家选举。
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方（不需要合同）
— 接收器内部交换矩阵，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，我们在交换矩阵外部有接收器，在EPG101中应用L3out_to_Core和mcast源之间的合同。
验证
PIM验证
当为组播路由启用VRF时，将为交换矩阵内的组播路由创建一个交换矩阵接口（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问候。 L3Out接口在正常模式下运行PIM，包括发送和接收问询、选举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问询，但不发送PIM问询。非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
如果使用组播路由启用了多个边界枝叶，APIC会为所有活动边界枝叶上的每个组地址选择一个条带赢家。作为组的条带赢家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。
组的条带赢家决定指定转发器。如果条带赢家具有到根的可达性，则条带赢家也是DF。如果条带赢家没有到根的外部连接，则BL通过交换矩阵接口发送PIM加入来选择DF。
