步骤
1、使用ACL创建将要匹配的路由条目
2、使用route-map匹配ACL
3、在重分布路由（redistribute）时调用route-map
Example
演示
使用Standard ACL过滤10.5.1.0/24、10.4.1.0/27路由条目重分布进OSPF
使用Extended ACL过滤10.3.3.0/30、10.2.0.0/24、10.2.1.0/25路由条目重分布进EIGRP
此示例使用的拓扑图 
IP地址、动态路由协议及重分布配置
在此只截取部分主要配置以供参考，IP配置省略，只截取路由配置
在配置EIGRP时，可以用network 0.0.0.0 0.0.0.0（可省略为network 0.0.0.0）命令宣告所有路由器上活动接口所在的子网。
配置OSPF时，可以使用network 0.0.0.0 0.0.0.0 area 0命令宣告所在路由器活动接口所在的子网，此命令将宣告所有子网在同一区域。
配置OSPF时，环回接口需在接口下配置ip ospf network point-to-point以真实显示所配置子网信息，如不配置此命令，在路由表中将显示为32位掩码。
ACL 可用ip access-list standard(extended) NAME进入子条目配置匹配列表，
也可用access-list NUM(ACL号）来配置匹配列表，两都在配置时稍有区别，在配置每条命令时可用？来查看不同之处。
