我將它轉成Dynamips的設定檔 並寫下自己的實驗紀錄

這Lab是OSPF Over Frame Relay(FR)的設定練習
我的設定是
1. 先設定HQ, East, West 的interface
HQ:
hostname HQ
!
no ip domain lookup
!
interface Loopback1
ip address 10.1.1.1 255.255.255.0
!
interface Serial1/0
ip address 10.1.123.1 255.255.255.0
encapsulation frame-relay
frame-relay map ip 10.1.123.1 102
frame-relay map ip 10.1.123.2 102 broadcast
frame-relay map ip 10.1.123.3 103 broadcast
no frame-relay inverse-arp
no shutdown
!
line con 0
logging synchronous
!
end
East:
hostname East
!
no ip domain lookup
!
interface Loopback2
ip address 10.1.2.1 255.255.255.0
!
interface FastEthernet0/0
ip address 10.1.23.2 255.255.255.0
no shutdown
!
interface Serial1/0
ip address 10.1.123.2 255.255.255.0
encapsulation frame-relay
frame-relay map ip 10.1.123.1 201 broadcast
frame-relay map ip 10.1.123.2 201
frame-relay map ip 10.1.123.3 201 broadcast
no frame-relay inverse-arp
no shutdown
!
line con 0
logging synchronous
!
end
West:
hostname West
!
no ip domain lookup
!
interface Loopback3
ip address 10.1.3.1 255.255.255.0
!
interface FastEthernet0/0
ip address 10.1.23.3 255.255.255.0
no shutdown
!
interface Serial1/0
ip address 10.1.123.3 255.255.255.0
encapsulation frame-relay
frame-relay map ip 10.1.123.1 301 broadcast
frame-relay map ip 10.1.123.2 301 broadcast
frame-relay map ip 10.1.123.3 301
no frame-relay inverse-arp
no shutdown
!
line con 0
logging synchronous
!
end
2. 設定NBMA OSPF
HQ:
router ospf 1
network 10.1.1.0 0.0.0.255 area 0
network 10.1.123.0 0.0.0.255 area 0
!
interface Loopback1
ip ospf network point-to-point
East:
router ospf 1
network 10.1.2.0 0.0.0.255 area 0
network 10.1.123.0 0.0.0.255 area 0
!
interface Loopback2
ip ospf network point-to-point
Wast:
router ospf 1
network 10.1.3.0 0.0.0.255 area 0
network 10.1.123.0 0.0.0.255 area 0
!
interface Loopback3
ip ospf network point-to-point
會發現OSPF沒有建立起鄰接關係
HQ&East&Wast:
show ip ospf neighbor
show ip ospf database
show ip ospf interface serial 1/0
為什麼??因為Network Type NON_BROADCAST 需要手動指定鄰接關係
HQ:
router ospf 1
neighbor 10.1.123.2
neighbor 10.1.123.3
再將HQ成為DR 可節省FR的頻寬
East&Wast:
interface Serial1/0
ip ospf priority 0
3. Changing the Network Type to Point-to-Multipoint
先恢復上一步
HQ:
router ospf 1
no neighbor 10.1.123.2
no neighbor 10.1.123.3
East&Wast:
interface Serial1/0
no ip ospf priority 0
改變Network Type 為 Point-to-Multipoint
HQ&East&Wast:
interface serial 1/0
ip ospf network point-to-multipoint
4. Changing OSPF Timers
East&Wast:
router ospf 1
network 10.1.23.0 0.0.0.255 area 0
!
interface fastEthernet 0/0
ip ospf hello-interval 5
ip ospf dead-interval 15
5. 驗證指令
show fram-relay pvc
show ip ospf neighbor
show ip route ospf
show ip ospf interface
ping
HQ設定檔:
hostname HQ
!
no ip domain lookup
!
interface Loopback1
ip address 10.1.1.1 255.255.255.0
ip ospf network point-to-point
!
interface Serial1/0
ip address 10.1.123.1 255.255.255.0
encapsulation frame-relay
ip ospf network point-to-multipoint
frame-relay map ip 10.1.123.1 102
frame-relay map ip 10.1.123.2 102 broadcast
frame-relay map ip 10.1.123.3 103 broadcast
no frame-relay inverse-arp
!
router ospf 1
network 10.1.1.0 0.0.0.255 area 0
network 10.1.123.0 0.0.0.255 area 0
!
line con 0
logging synchronous
!
end

ip ospf hello-interval 5
ip ospf dead-interval 15
!
interface Serial1/0
ip address 10.1.123.2 255.255.255.0
encapsulation frame-relay
ip ospf network point-to-multipoint
frame-relay map ip 10.1.123.1 201 broadcast
frame-relay map ip 10.1.123.2 201
frame-relay map ip 10.1.123.3 201 broadcast
no frame-relay inverse-arp
!
router ospf 1
network 10.1.2.0 0.0.0.255 area 0
network 10.1.23.0 0.0.0.255 area 0
network 10.1.123.0 0.0.0.255 area 0
!
line con 0
logging synchronous
!
end
West設定檔:
hostname West
!
no ip domain lookup
!

frame-relay map ip 10.1.123.2 301 broadcast
frame-relay map ip 10.1.123.3 301
no frame-relay inverse-arp
