减压稳压消火栓有几种:CCNP:用Router模拟帧中继交换机配置实验 - 中国思科华为3COM网络技术认证专业...

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

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
