邏輯子接口-幀中繼實現局域網互聯

幀中繼實現局域網互聯

用幀中繼實現局域網互聯，拓撲如下：

R1配置如下：
interface Loopback0
ip address 192.168.1.1 255.255.255.0

interface Serial1/0
no ip address
encapsulation frame-relay
serial restart-delay 0
no frame-relay inverse-arp
!
interface Serial1/0.2 multipoint
ip address 12.12.12.1 255.255.255.0
no ip split-horizon
frame-relay map ip 12.12.12.2 102 broadcast
frame-relay map ip 12.12.12.3 103 broadcast
no frame-relay inverse-arp
!
R2配置如下：
interface Loopback0
ip address 192.168.2.2 255.255.255.0
!

interface Serial1/0
ip address 12.12.12.2 255.255.255.0
encapsulation frame-relay
serial restart-delay 0
frame-relay map ip 12.12.12.1 201 broadcast
no frame-relay inverse-arp
!
R3配置如下：
interface Loopback0
ip address 192.168.3.3 255.255.255.0
!
interface Serial1/0
ip address 12.12.12.3 255.255.255.0
encapsulation frame-relay
serial restart-delay 0
frame-relay map ip 12.12.12.1 301 broadcast
no frame-relay inverse-arp
!
FR配置如下：
interface Serial1/0
no ip address
encapsulation frame-relay
serial restart-delay 0
clock rate 64000
frame-relay intf-type dce
frame-relay route 102 interface Serial1/1 201
frame-relay route 103 interface Serial1/2 301
!
interface Serial1/1
no ip address
encapsulation frame-relay
serial restart-delay 0
clock rate 64000
frame-relay intf-type dce
frame-relay route 201 interface Serial1/0 102
!
interface Serial1/2
no ip address
encapsulation frame-relay
serial restart-delay 0
clock rate 64000
frame-relay intf-type dce
frame-relay route 301 interface Serial1/0 103
!
現在只能從R1 ping通12.12.12.2，從R2 ping通12.12.12.1
從R1 ping通12.12.12.3，從R3 Ping通12.12.12.1
其他的都不通，求諸位大神幫個忙，在線等

啊啊啊，原來在幀中繼網絡中OSPF需要設置為broadcast才可以
