帧中继多点子接口、单点子接口配置试验

拓扑图以下：

首先作下帧中继交换机的配置：

FRSwitch:

frame-relay switching

interface s1/0

encapsulation frame-relay

no shut

frame-relay intf-type dce

frame-relay lmi-type cisco

clock rate 64000

interface s1/1

encapsulation frame-relay

no shut

frame-relay intf-type dce

frame-relay lmi-type cisco

clock rate 64000

interface s1/2

encapsulation frame-relay

no shut

frame-relay intf-type dce

frame-relay lmi-type cisco

clock rate 64000

interface s1/3

encapsulation frame-relay

no shut

frame-relay intf-type dce

frame-relay lmi-type cisco

clock rate 64000

接下来，咱们要配置frame-relay route用来定义接口上DLCI并与对端DLCI造成一个PVC

interface s1/0

frame-relay route 102 interface s1/1 100

frame-relay route 103 interface s1/2 130

interface s1/1

frame-relay route 100 interface s1/0 102

interface s1/2

frame-relay route 130 interface s1/0 103

帧中继交换机的配置咱们已经结束

R1：

interface lo0

ip address 1.1.1.1 255.255.255.0

no shut

exit

interface s1/0

no shut

encapsulation frame-relay

no ip address

interface s1/0.1 multipoint

ip address 192.168.1.101 255.255.255.0

no shut

frame-relay map ip 192.168.1.101 101

frame-relay map ip 192.168.1.102 102 broadcast

frame-relay map ip 192.168.1.103 103 broadcast

用来将IP和DLCI进行一个映射

EIGRP的配置：

router eigrp 90

network 192.168.1.0 0.0.0.255

network 1.1.1.1 0.0.0.0

no auto-summary

eigrp router-id 1.1.1.1

R2：

interface lo0

ip address 2.2.2.2 255.255.255.0

no shut

exit

interface s1/0

encapsulation frame-relay

no shut

no ip address

interface s1/0.1 multipoint

ip add 192.168.1.102 255.255.255.0

no shut

frame-relay map ip 192.168.1.102 100 broadcast

exit

router eigrp 90

network 192.168.1.0 0.0.0.255

network 2.2.2.2 0.0.0.0

no auto-summary

eigrp router-id 2.2.2.2

R3:

interface lo0

ip address 3.3.3.3 255.255.255.0

no shut

exit

interface s1/0

encapsulation frame-relay

no shut

no ip address

interface s1/0.1 multipoint

ip address 192.168.1.103 255.255.255.0

no shut

frame-relay map ip 192.168.1.103 130 broadcast

router eigrp 90

network 192.168.1.0 0.0.0.255

network 3.3.3.3 0.0.0.0

no auto-summary

eigrp router-id 3.3.3.3

看到了吧

R2和R3上彼此的环回口网络没有回去由于水平分割的问题

因此须要在R1上的S1/0.1接口上关闭水平分割

interface s1/0.1 multipoint

no ip split-horizon eigrp 90

这样路由表就能够获取了。

这种适合帧中继全互联或局部互联的拓扑结构

下面咱们来配置单点子接口的配置，适用于HUB-SPOKER拓扑结构

帧中继交换机配置同上

R1：

interface s1/0

encapsulation frame-relay

no shut

interface s1/0.2 point-to-point

ip address 192.168.2.1 255.255.255.0

no shut

frame-relay interface-dlci 102

interface s1/0.3 point-to-point

ip address 192.168.3.1 255.255.255.0

no shut

frame-relay inteface-dlci 103

interface lo0

ip address 1.1.1.1 255.255.255.0

no shut

router eigrp 90

network 192.168.2.0 0.0.0.255

network 192.168.3.0 0.0.0.255

no auto-summary

eigrp router-id 1.1.1.1

network 192.168.2.0 0.0.0.255

network 2.2.2.2 0.0.0.0

no auto-summary

eigrp router-id 2.2.2.2

no shut

interface s1/0

encapsulation frame-relay

no shut

interface s1/0.3

network 3.3.3.3 0.0.0.0

no auto-summary

eigrp router-id 3.3.3.3

呵呵，配置结束。不用配置水平分割，就能够获取全部的路由条目
