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

R1 ========================================== host R1 no ip domain-look line con 0 logg sy exec-time 0 0 ! int s1/2 encap frame ip add 192.168.192.1 255.255.255.0 no sh frame map ip 192.168.192.2 102 broadcast frame map ip 192.168.192.4 103 broadcast ! int loop 0  ip add 192.168.10.10 255.255.255.0 R2 ========================================== host R2 no ip domain-look line con 0 logg sy exec-time 0 0 ! int s1/2 encap frame ip add 192.168.192.2 255.255.255.0 no sh frame map ip 192.168.192.1 201 broadcast frame map ip 192.168.192.4 201 broadcast no frame inverse-arp int loop 0  ip add 192.168.20.20 255.255.255.0 ! R3 ========================================== host R3 no ip domain-look line con 0 logg sy exec-time 0 0 ! int s1/2 encap frame ip add 192.168.192.4 255.255.255.0 no sh frame map ip 192.168.192.1 301 broadcast frame map ip 192.168.192.2 301 broadcast no frame inverse-arp int loop 0  ip add 192.168.30.30 255.255.255.0 ! R7 ========================================== 路由器模拟frame-relay交换机配制 host Frame-Swith no ip domain-look line con 0 logg sy exec-time 0 0 ! frame switching ! interface Serial1/0  no ip directed-broadcast  clock rate 56000  encapsulation frame-relay  frame-relay intf-type dce  frame-relay route 102 interface Serial1/1 201  frame-relay route 103 interface Serial1/2 301  no sh ! interface Serial1/1  no ip directed-broadcast  clock rate 56000  encapsulation frame-relay  frame-relay intf-type dce  frame-relay route 201 interface Serial1/0 102  no sh ! interface Serial1/2  no ip directed-broadcast  clock rate 56000   encapsulation frame-relay  frame-relay intf-type dce  frame-relay route 301 interface Serial1/0 103  no sh !  

 

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
