07-IP组播配置举例

02-S12500_IPv6_PIM-SM典型配置举例

1 简介

本文档介绍了IPv6 PIM-SM配置举例。

IPv6 PIM-SM（Protocol Independent Multicast-Sparse Mode，稀疏模式协议无关组播）属于稀疏模式的IPv6组播路由协议，使用“拉（Pull）模式”传送IPv6组播数据，通常适用于IPv6组播组成员分布相对分散、范围较广的大中型网络。

2 配置前提

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IPv6 PIM-SM特性。

3 配置举例

3.1 组网需求

如图1所示，三层交换机Switch A、Switch B和Switch C之间采用OSPFv3协议进行互连，IPv6单播路由正常。接收者通过IPv6组播方式接收视频点播信息，末梢用户网络N1、N2、N3中存在不同视频信息的接收者。

要求在该网络中采用IPv6 PIM-SM协议实现IPv6组播数据的分发，并通过自举机制来动态选举RP，同时配置静态RP以避免动态RP故障而使通信中断。

图1 IPv6 PIM-SM配置组网图

设备	接口	IPv6地址	设备	接口	IPv6地址
Switch A	Vlan-int100(GE3/0/1)	2001:100::1/64	Switch C	Vlan-int102(GE3/0/1)	2001:102::1/64
	Vlan-int12(GE3/0/2)	2001:12::1/64		Vlan-int13(GE3/0/3)	2001:13::3/64
	Vlan-int13(GE3/0/3)	2001:13::1/64		Vlan-int23(GE3/0/2)	2001:23::3/64
	Loopback0	2001:2001::1/128		Vlan-int33(GE3/0/4)	2001:33::3/64
Switch B	Vlan-int101(GE3/0/1)	2001:101::1/64
	Vlan-int12(GE3/0/2)	2001:12::2/64
	Vlan-int23(GE3/0/3)	2001:23::2/64

3.2 配置思路

· 为了确保一个C-RP故障时，另一个C-RP能够生效，将Switch A的Loopback接口0和Switch B的VLAN接口12均为配置C-RP，其中前者的优先级较高；同时为了确保上述两个接口都发生故障时静态RP能够生效，将Swtich C的VLAN接口13配置为静态RP。

· 为了能动态选举出RP，需要在Switch A和Switch B上配置C-BSR来自动选举产生BSR，以负责收集C-RP发来的宣告报文。

3.3 使用版本

本举例是在S12500-CMW710-R7129版本上进行配置和验证的。

3.4 配置注意事项

· 同一台设备所有接口上所使能的IPv6 PIM模式必须相同。

· BSR和RP接口必须使能IPv6 PIM-SM。

· 在边界设备连接用户网络的接口上必须使能MLDv1功能，以建立和维护各IPv6组播组的成员关系。
