CCNA R&S CCNA 5.0 Câu lệnh cấu hình Frame relay
– Cấu hình map động
+ Bước 1: cấu hình int se như bình thường, có đặt ip
R1(config)#int se0/0/0
R1(config-if)#ip add 10.1.1.1 255.255.255.0
R1(config-if)#no shut
+ Bước 2: Cấu hình đóng gói Frame-relay trên int se
R1(config-if)#encapsulation frame-relay cấu hình đóng gói frame-relay
R1(config-if)#frame-relay interface-dlci 102 gán chỉ số DLCI trong hợp đồng thuê kênh vào int vật lý.
–Câu lệnh cấu hình int serial đóng gói Frame relay và map tĩnh IP nexthop với DLCI
R1(config)#int se0/0/0
R1(config-if)#ip add 10.1.1.1 255.255.255.0
R1(config-if)#no shut
R1(config-if)#encapsulation frame-relay cấu hình đóng gói frame-relay
R1(config-if)#no frame-relay inverse-arp bỏ map động bằng inverse-arp mặc định trên int được cấu hình Frame-relay
R1(config-if)#frame-relay map ip 10.1.1.2 102 broadcast cisco Cấu hình map tĩnh ip nexthop là 10.1.1.2 với chỉ số DLCI local là 102
Cấu hình subint
HubCity
HubCity(config)#int serial 0
HubCity(config-if)#no shut
HubCity(config-if)#encapsulation frame-relay
interface Serial0.1 multipoint
ip address 172.16.3.3 255.255.255.0
frame-relay interface-dlci 301
frame-relay interface-dlci 302
Spokane
interface Serial0.1 point-to-point
ip address 172.16.3.1 255.255.255.0
frame-relay interface-dlci 103
Spokomo
interface Serial0.1 point-to-point
ip address 172.16.3.2 255.255.255.0
frame-relay interface-dlci 203
Cấu hình giả môi trường broadcast cho OSPF
RouterA(config-if)#ip ospf network-type broadcast
NBMA – non-broadcast multiaccess không hỗ trợ broadcast. Vì vậy OSPF không gửi ra bản tin LSA theo kiểu multicast. Vì vậy ở tần 3 cần có câu lệnh để giả lập môi trường Frame relay thành broadcast mới truyền được các bản tin multicast và broadcast.
