06-三层组播支持M-LAG典型配置举例
本章节下载： 06-三层组播支持M-LAG典型配置举例 (327.62 KB)
本文档介绍了三层组播支持M-LAG（组播源在M-LAG系统侧）和IPv6三层组播支持M-LAG（组播源在M-LAG系统侧）的配置举例。
PIM/IPv6利用M-LAG（Multichassis link aggregation，跨设备链路聚合）功能将两台物理设备连接起来虚拟成一台设备，使用该虚拟设备连接组播源或组播接收者，可避免单点故障对组播网络造成影响，提高组播网络可靠性。
本文档中的配置均是在实验室环境下进行的配置和验证，配置前设备的所有参数均采用出厂时的缺省配置。如果您已经对设备进行了配置，为了保证配置效果，请确认现有配置和以下举例中的配置不冲突。
本文假设您已了解三层组播支持M-LAG特性。
· 网络中运行OSPF协议，接收者通过组播方式接收视频点播信息，不同组织的接收者群体组成末梢网络，每个末梢网络中都存在至少一个接收者，整个PIM域采用SM非管理域方式。
· DeviceC作为二层设备，通过接口HundredGigE1/0/5与组播源互联，通过聚合口1与Device A和Device B形成的M-LAG系统互联。组播源发送的组播数据流量，通过Device C的聚合口进行负载分担，发送到Device A和Device B的M-LAG接口上。Device A和Device B上的Vlan-interface20接口上配置的IP地址作为组播源接入M-LAG系统的网关地址。组播接收者Host A通过Device D接入M-LAG系统。
· 配置Device A和Device B的三层以太网接口HundredGigE1/0/3为保留接口，在该三层以太网接口上搭建Keepalive链路，保证Keepalive报文能够正常传输。
· 在Device A的Vlan-interface 20接口上配置VRRP，设置Device A在备份组1中的优先级为200，以保证Device A成为Master，从而与Device A在M-LAG中角色一致。
· Device A和Device B的M-LAG接口上，允许VLAN 20通过，并在各自的Vlan-interface 20接口上配置PIM协议。
· Device A和Device B上使能IP组播路由功能。
