八、用路由器模拟帧中继交换机配制
8.1、拓扑图
（注：这个模拟完全可以用模拟器作，而且IE的机试一定要考的）
图上所示是一个部分网状的帧中继的拓扑，其中R7中模拟帧中继交换机，R1为中心路由器，R2和R3为分支路由器
8.2、基本配制

当所有基本都配制好后，我们就可以在R1、R2、R3之间互相ping串口的IP，如果能通就说明帧中继正常工作。但是我们是不能ping 对方的loopback０的地址。
当然也可以用一些查看帧中继的命来查看
Show fram map
Show fram pvc
Show ip route
来验证
8.3、配制OSPF
注意事项：配制时须要指明网络类型
R1:
int s1/2
ip ospf network point-to-multipoint
router ospf 1
net 192.168.192.0 0.0.0.255 area 0
net 192.168.10.0 0.0.0.255 area 0
R2：
int s1/2
ip ospf network point-to-multipoint
router ospf 1
net 192.168.192.0 0.0.0.255 area 0
net 192.168.20.0 0.0.0.255 area 0
R3：
int s1/2
ip ospf network point-to-multipoint
router ospf 1
net 192.168.192.0 0.0.0.255 area 0
net 192.168.30.0 0.0.0.255 area 0
此时配制完成
我们可以在一个路由器上ping另一个路由器的loopback0地址，如果通就说明配制成功
也可以用show ip route来查看是不是有对方的loopback0路由
