CCNA - Cấu hình Frame-Relay SubInterfaces Point to point

Mô tả và yêu cầu
- Cấu hình EIGRP qua frame-relay 
- Tại hub RA sử dụng 2 subinterface point to point
- Tại spoke RB và RC cấu hình subinterface point to point

Các bước thực hiện


Bước 1: Cấu hình Frame Relay Switch

Code: 

FRSwitch#configure terminal
FRSwitch(config)#frame-relay switching //bật tính năng frame-relay trên router
FRSwitch(config)#interface s0/0
FRSwitch(config-if)#no ip address   //chú ý không đặt địa chỉ
FRSwitch(config-if)#encapsulation frame-relay
FRSwitch(config-if)#clock rate 64000
FRSwitch(config-if)#frame-relay intf-type dce//dce này khác với dce của dây serial
FRSwitch(config-if)#frame-relay route 200 interface s0/1 200
FRSwitch(config-if)#exit

FRSwitch(config)#interface s0/1
FRSwitch(config-if)#no ip address
FRSwitch(config-if)#encapsulation frame-relay
FRSwitch(config-if)#clock rate 64000
FRSwitch(config-if)#frame-relay intf-type dce
FRSwitch(config-if)#frame-relay route 200 interface s0/0 200
FRSwitch(config-if)#frame-relay route 100 interface s0/2 100
FRSwitch(config-if)#exit

FRSwitch(config)#interface s0/2
FRSwitch(config-if)#no ip address
FRSwitch(config-if)#encapsulation frame-relay
FRSwitch(config-if)#clock rate 64000
FRSwitch(config-if)#frame-relay intf-type dce
FRSwitch(config-if)#frame-relay route 100 interface s0/1 100

Bước 2: Cấu hình Router A

Code: 

RouterA(config)#interface s0
RouterA(config-if)#no ip address
RouterA(config-if)#encapsulation frame-relay
RouterA(config-if)#no shutdown
RouterA(config-if)#exit
RouterA(config)#interface serial 0.1 point-to-point
RouterA(config-if)#ip address 192.168.1.2 255.255.255.0
RouterA(config-if)#frame-relay interface dlci 200
RouterA(config-if)#no shutdown
RouterA(config-if)#exit

RouterA(config)#interface ethernet 0
RouterA(config-if)#ip address 172.16.1.1 255.255.255.0
RouterA(config-if)#no shut
RouterA(config-if)#exit

RouterA(config)#router eigrp 100
RouterA(config-router)#network 172.16.0.0
RouterA(config-router)#network 192.168.1.0

Bước 3: Cấu hình Router B

Code: 

RouterB(config)#interface s0
RouterB(config-if)#no ip address
RouterB(config-if)#encapsulation frame-relay
RouterB(config-if)#no shutdown
RouterB(config-if)#exit

RouterB(config)#interface serial 0.1 point-to-point
RouterB(config-subif)#ip address 192.168.2.2 255.255.255.0
RouterB(config-subif)#frame-relay interface dlci 100
RouterB(config-subif)#no shutdown
RouterB(config-subif)#exit

RouterB(config)#interface ethernet 0
RouterB(config-if)#ip address 172.16.2.1 255.255.255.0
RouterB(config-if)#no shut
RouterB(config-if)#exit

RouterB(config)#router eigrp 100
RouterB(config-router)#network 172.16.0.0
RouterB(config-router)#network 192.168.1.0

 

Bước 4: Cấu hình Router C

Code: 

RouterC(config)#interface serial 0
RouterC(config-if)#no ip address
RouterC(config-if)#encapsulation frame-relay
RouterC(config-if)#no shutdown
RouterC(config-if)#exit

RouterC(config)#interface serial 0.1 point-to-point
RouterC(config-subif)#ip address 192.168.1.1 255.255.255.0
RouterC(config-subif)#frame-relay interface dlci 100
RouterC(config-subif)#no shutdown
RouterC(config-subif)#exit

RouterC(config)#interface serial 0.2 point-to-point
RouterC(config-subif)#ip address 192.168.2.1 255.255.255.0
RouterC(config-subif)#frame-relay interface dlci 200
RouterC(config-subif)#no shutdown
RouterC(config-subif)#exit

RouterC(config)#interface ethernet 0
RouterC(config-if)#ip address 172.16.3.1 255.255.255.0
RouterC(config-if)#no shut
RouterC(config-if)#exitRouterC(config)#router eigrp 100
RouterC(config-router)#network 172.16.0.0
RouterC(config-router)#network 192.168.1.0
RouterC(config-router)#network 192.168.2.0

Bước 5: Kiểm tra trên Router A, Router B, Router C

Code: 

Router#show frame-relay pvc
Router#show frame-relay lmi
Router#show frame-relay route
Router#show frame-relay map
