目 录
本文档介绍了OSPF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OSPF路由信息过滤的特性。
如图1所示，公司A使用OSPF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RIP路由协议与公司A的OSPF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OSPF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R2825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OSPF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全部过滤掉。

核心网接入承载网组网中，需要通过OSPF多实例隔离不同业务的路由。
如图3所示，各设备承担的角色分别为：
· Device A为网关设备，称为GW。
· Device B和Device C为核心网设备，称为CE。
· Device D和Device E为承载网设备，称为AR。
本举例中业务1接入VPN1，业务2接入VPN2。通过OSPF多实例隔离业务1和业务2的路由，需要做如下部署：
· GW上创建两个VPN实例vpn1和vpn2。
· GW上创建两个OSPF进程OSPF 15和OSPF 115。将OSPF 15与vpn1绑定，OSPF 115与vpn2绑定。
· CE和AR上分别创建两个VPN实例vpn1和vpn2。
· CE和AR上分别创建两个OSPF进程OSPF 15和OSPF 115。将OSPF 15与vpn1绑定，OSPF 115与vpn2绑定。
· CE上将不同业务的路由分别汇总为静态黑洞路由，然后在OSPF中引入汇总后的静态黑洞路由，并通过路由策略控制引入的路由。这样可以避免CE将业务明细路由发布给AR，减少AR上的路由条目数量，降低路由震荡的风险。
CE 1和CE 2上的业务网段分别为（本例中使用LoopBack接口模拟不同的业务网段）：
¡ CE 1上vpn1业务网段为19.0.0.0/24，vpn2业务网段为20.0.0.0/24。
¡ CE 2上vpn1业务网段为21.0.0.0/24，vpn2业务网段为22.0.0.0/24。
