帧中继点到多点子接口

实验目的：了解怎么样配置点到点子接口；解决水平分割问题

实验拓扑：（R3。R4使用帧中继主接口，在R1上创建点到多点子接口）

 

 

 

R1：

ena

conf t

no ip domain-loo

line cons 0

logging syn

no exec-t

int s0/0

no ip add                  //主接口下不需要IP地址

encapsulation frame-relay         // 启用帧中继封装协议 

no frame-relay inv          //关闭自动映射

no shut

int s0/0.1 multipoint                          //创建点到点子接口

ip add 192.168.123.1 255.255.255.0

frame-relay map ip 192.168.123.3 103 broadcast

frame-relay map ip 192.168.123.4 104 broadcast            //配置帧中继映射

int lo0

ip add 1.1.1.1 255.255.255.0

 

router rip

net 1.0.0.0

net 192.168.123.0

 

 

R2:

frame-relay switching
int s0/0
no shutdown
clock rate 64000
encapsulation frame-relay
frame-relay lmi-type cisco
frame-relay intf-type dce
frame-relay route 103 interface s0/1 301
frame-relay route 104 interface s0/2 401

int s0/1
no shutdown
clock rate 64000
encapsulation frame-relay
frame-relay lmi-type cisco
frame-relay intf-type dce
frame-relay route 301 interface Serial0/0 103

int s0/2
no shutdown
clock rate 64000
encapsulation frame-relay
frame-relay lmi-type cisco
frame-relay intf-type dce
frame-relay route 401 interface Serial0/0 104

 

R3:

 

int s0/1

ip add 192.168.123.3 255.255.255.0

encapsulation frame-relay

no frame-relay inv

frame-relay map ip 192.168.123.1 301 broadcast

no shut

int lo0

ip add 3.3.3.3 255.255.255.0

router rip

net 3.0.0.0

net 192.168.123.0

 

R4:

int s0/2

ip add 192.168.123.4 255.255.255.0

encapsulation frame-relay

no frame-relay inv

frame-relay map ip 192.168.123.1 401 broadcast

no shut

int lo0

 ip add 4.4.4.4 255.255.255.0

router rip

net 192.168.123.0

net 4.0.0.0
