实验过程涉及知识：分发列表(distribute-list)、管理距离(distance)、邻居关系(neighbor)、访问控制列表(access-list)。
实验过程描述：首先什么都不做，只是让交换机和路由器能互相学习到对方的信息，然后再添加分发列表、管理距离等，最后查看所有设备的路由表以检验实验是否成功。

配置完基础命令，检查一下交换机的路由表。
SW#show ip route

SW#
给交换机 SW 配置管理距离；给路由器 R1 配置被动端口、分发列表。
SW(config)#router rip
SW(config-router)#distance 100 192.168.34.1 0.0.0.0
R1#conf t
R1(config)#access-list 10 permit 10.10.34.0 0.0.0.255
R1(config)#router rip
R1(config-router)#passive-interface f0/0
R1(config-router)#neighbor 192.168.34.3
R1(config-router)#distribute-list 10 out f0/0
R1(config-router)#end
此时再查看交换机 SW 的路由表，将收不到路由器 R1 的 Loop 1 端口的路由信息(默认被拒绝)。
