route-map做过滤

实验目的:
        1:熟练配置路由重分发
        2:利用route-map过滤相应的路由

实验拓扑:



实验步骤和要求:

     3人一组(或者一人独立完成),由授课老师负责分配设备并掩饰配置路由协力和重分发,并说明如何通过配置route-map来过滤路由。最终由学生按实验 要求独力配置。

实验要求:
       1:在london上看到192.168.1.0/3.0/5.0/7.0的网络
       2:在denver上不看到172.16.2.0/4.0/6.0/8.0的网络

1:具体配置

End

按拓扑要求配置路由器的各个接口,并起用ospf,把所有直链网络宣告进ospf,且属于area0。

route-map isis-ospf permit 10 (具体定义策略isis-ospf的内容,符合地址的被分发)

!
route-map ospf-isis deny 10(具体定义ospf-isis的策略内容,符合地址的被分发)
match ip address 2
!
route-map ospf-isis permit 20
!
end

按要求配置该路由器的各个接口,并起用ospf和isis,把相映的网络宣告进两种协议,最后分别在两种协力里做了双向的重分发,并且要满足策略内 容的才可以被分发出去。

按要求配置该路由器的各个接口,并在各个接口下起用isis,最后在全局模式下启用isis,且规定isis的区域为1。


1:仔细观察路由表,观察实验现象

2:熟悉route-map的其他参数

3:比较route-map和distribute-list的区别
