import-route命令用来从其它路由协议或其它IS-IS进程引入路由信息。
undo import-route命令用来取消从其它路由协议或其它IS-IS进程引入路由信息。

undo import-route { bgp4+ | direct | { isisv6 | ospfv3 | ripng } [ process-id | all-processes ] | static }
【缺省情况】
IS-IS不引入其它协议的路由信息。

在ISIS下使用Import-route命令重分布即可。
以下是配置案例，请参考：
组网说明：
本案例采用H3C HCL模拟器的S5820来模拟IPV6 静态路由与ISIS路由重分布的典型组网配置。SW1与SW2运行静态路由协议，SW2与SW3运行ISIS路由协议，为了实现物理机能够PING通SW3，因此需要在SW2配置静态路由与ISIS路由重分布。
配置步骤
1、按照网络拓扑图正确配置IP地址
2、SW1与SW2运行静态路由协议
3、SW2与SW3运行ISIS路由协议
4、SW2配置静态与ISIS路由重分布
配置关键点
SW1:
<H3C>sys
System View: return to User View with Ctrl+Z.
[H3C]sysname SW1
[SW1]int gi 1/0/2

[SW3-GigabitEthernet1/0/2]quit
测试：
物理机填写IPV6地址：
物理机能PING通SW3的loopback 1:
分别查看SW2、SW3的ISIS邻居信息：
分别查看SW1、SW2、SW3的IPV6路由表：
