1  简介

本文档介绍IPv6 IS-IS配置举例。

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。

本文档假设您已了解IPv6 IS-IS特性。

3  配置举例

3.1  组网需求

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

3.2  配置思路

·     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。

(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。
