1、用路由器模拟帧中继交换机配置（GNS3_C3640 模拟修正版）1、拓扑图 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 2、基本配置R1 =host R1no ip domain-lookline con 0logg syexec-time 0 0!int s1/2encap frameip add 192.168.192.1 255.255.255.0no shframe map ip 192.168.192.2 102 broadcastframe map ip 192.168.192.4 103 broadcas

6、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 通对方的 loopback的地址。当然也可以用一些查看帧中继的命来查看Show fram mapShow fram pvcShow ip route来验证3、配制 OSPF注意事项：配制时须要指明网络类型R1:int s1/2ip ospf network point-to-multipointrouter ospf 1net 192.168.192.0 0.0.0.255 area 0net 192.168.10.0 0.0.0.255 area 0R
7、2：int s1/2ip ospf network point-to-multipointrouter ospf 1net 192.168.192.0 0.0.0.255 area 0net 192.168.20.0 0.0.0.255 area 0R3：int s1/2ip ospf network point-to-multipointrouter ospf 1net 192.168.192.0 0.0.0.255 area 0net 192.168.30.0 0.0.0.255 area 0此时配置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。
