目 录
本文档介绍了OSPFv3路由信息过滤的配置举例。
本文档不严格与具体软、硬件版本对应,如果使用过程中与产品实际情况有差异,请参考相关产品手册,或以设备实际情况为准。
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。
本文档假设您已了解OSPFv3路由信息过滤的特性。
如图1所示,公司A使用OSPFv3路由协议实现公司设备全网互通,后来公司A扩张兼并了公司B,要求将公司B采用的RIPng路由协议与公司A的OSPFv3协议互相引入,使得各个部门可以实现互通。Device A和Device B作为公司核心设备负责各个部门间的通信。由于业务需要,现要求通过下列措施控制并调整网络中的路由信息:
· 在Device E上对引入的路由信息进行过滤,使得研发二部所在网段无法被引入到OSPFv3内。
· 在Device C上使用路由信息的过滤功能,使得市场一部所在网段无法访问研发一部。
· 在Device D上使用路由信息的过滤功能,使得研发一部和售后服务部所在网段无法访问市场二部。

本举例是在S6890-CMW710-R2712版本上进行配置和验证的。
· 路由信息过滤功能中对于引入外部路由信息时采用export关键字进行过滤,该参数只能在ASBR上生效。
· 路由信息过滤功能只是对路由表中相关路由信息过滤,并不是过滤掉OSPFv3中通告的LSA。
· 由于路由通信是双向的,使用路由信息过滤功能将某一目的网段过滤后,该路由器下联的其它网段无法访问这个目的网段的设备,这个目的网段的设备也不能访问源地址网段的设备。
· 使用路由信息过滤功能配合ACL使用时,必须将最后一条规则设置为允许所有源地址通过才能避免将所有网段路由被全部过滤掉。
· 配置OSPFv3时必须手工指定Router ID。
· 缺省情况下,S6890系列交换机的接口处于ADM(Administratively Down)状态,请根据实际需要在对应接口视图下使用undo shutdown命令开启接口。

综合Device C和Device D的路由表信息,发现路由表中均没有14::/64网段路由信息,说明设备已经将引入OSPFv3的RIPng路由中研发二部所在网段过滤掉。
