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SwitchA、SwitchB和SwitchC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均配置为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，还需要在SwitchA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-CMW520-R1825P01版本上进行配置和验证的。

3.4  配置注意事项

·     为实现IPv6报文在各个交换机上能正常转发，必须先使能IPv6报文转发功能（缺省情况为关闭）。

·     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。

(2)     通过使用display ipv6 pim rp-info命令可以查看IPv6 PIM-SM域中的RP信息。

# 查看SwitchB上所有IPv6组播组对应的RP信息。
