目 录
本文档介绍IPv6 IS-IS配置举例。
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IPv6 IS-IS特性。
如图1所示,某公司总部和分部使用IPv6 IS-IS路由协议进行互联。公司总部内为市场部(Mkt dept.)和财务部(F&A dept.)设置了独立的网络。该公司的合作伙伴使用的是OSPFv3路由协议。现要求:
· 公司总部内市场部和财务部可以通信;并通过配置路由渗透功能,实现总部与分部间,市场部与分部可以正常通信,财务部与分部无法通信,且分部无法查看到财务部的路由信息。
· 将合作伙伴的OSPFv3路由引入公司分部的网络中,并保证市场部与合作伙伴可以通信。
图1 IPv6 IS-IS配置组网图
· 为了实现公司总部内市场部和财务部的相互通信,在area 10区域部署Level-1路由器。
· 为了使公司总部内财务部和公司分部不能相互通信,且公司分部无法查看财务部的路由,需要通过在Switch C上配置IS-IS路由渗透并引用地址前缀列表来实现Level-1区域只将3001:1::/64网段的路由信息向Level-2发布。
· 为了实现公司总部内市场部与合作伙伴的网络互通,需要在Switch D的IS-IS进程中引入OSPF进程的路由,并在OSPF进程中引入IS-IS进程的路由。
本举例是在S12500-S-CMW710-R7150P02版本上进行配置和验证的。

(1) 在Switch D上查看IPv6 IS-IS路由表,可以查看到市场部(3001:1::/64)的路由,无法查看到财务部(3001:2::/64)的路由,说明公司分部只能与市场部通信。
