幀中繼的兩個實驗：點到點、點到多點
1、【點到點】 拓撲如下：
實驗步驟
幀中繼交換機設定
r1>r2 DLCI :102r1>r3 DLCI :103
注意：r2和r3之間是沒有PVC的。
r1上
interface FastEthernet0/0ip address 192.168.1.1 255.255.255.0 interface Serial0/0/0
no ip address
encapsulation frame-relay
!
interface Serial0/0/0.2 point-to-point
ip address 10.0.0.1 255.255.255.0
frame-relay interface-dlci 102
interface Serial0/0/0.3 point-to-point
ip address 10.0.1.1 255.255.255.0

version 2
network 10.0.0.0
network 192.168.1.0 r2上： interface FastEthernet0/0
ip address 192.168.2.1 255.255.255.0 interface Serial0/0/0
ip address 10.0.0.2 255.255.255.0

version 2
network 192.168.2.0 r3上： interface FastEthernet0/0
ip address 192.168.3.1 255.255.255.0 interface Serial0/0/0
ip address 10.0.1.2 255.255.255.0
encapsulation frame-relay router rip
version 2
network 10.0.0.0
network 192.168.3.0 測試：pc0去ping pc1和pc2
pc1去ping pc2
2、【點到多點】
拓撲同上
r1>r2 DLCI :102 r2>r1 DLCI :201r1>r3 DLCI :103 r3>r1 DLCI :301
實驗步驟：
R1上：
interface FastEthernet0/0ip address 192.168.1.1 255.255.255.0 interface Serial0/0/0
no ip address
encapsulation frame-relay
!

version 2
network 10.0.0.0
network 192.168.3.0 測試： R1的路由表：
R2的路由表：
R3的路由表：
PC0 ping PC1和PC2
PC1ping PC2
由於水平分割是不能ping通的！
