本次練習是參考Cisco網路學院
CCNP1 Building Scalable Internetworks v5.0
Student Lab Manual
我將它轉成Dynamips的設定檔 並寫下自己的實驗紀錄
Dynamips的設定檔:

autostart=false
[localhost:7200]

autostart = false
slot0 = NM-1FE-TX
slot1 = NM-4T

這Lab只是基本OSPF設定練習
我的設定是
1. 先設定R1-3每個介面的ip address
R1:
hostname R1
!
no ip domain lookup
!
interface Loopback1
ip address 10.1.1.1 255.255.255.0
!
interface FastEthernet0/0
ip address 10.1.200.1 255.255.255.0
no shutdown
!
interface Serial1/0
ip address 10.1.100.1 255.255.255.0
no shutdown
!
line con 0
logging synchronous
!
end
R2:
hostname R2
!
no ip domain lookup
!
interface Loopback2
ip address 10.1.2.1 255.255.255.0
!
interface FastEthernet0/0
ip address 10.1.200.2 255.255.255.0
no shutdown
!
interface Serial1/0
ip address 10.1.100.2 255.255.255.0
no shutdown
!
line con 0
logging synchronous
!
end
R3:
hostname R3
!
no ip domain lookup
!
interface Loopback3
ip address 10.1.3.1 255.255.255.0
!
interface FastEthernet0/0
ip address 10.1.200.3 255.255.255.0
no shutdown
!
line con 0
logging synchronous
!
end
2. 設定整個10.1.100.0 & 10.1.200.0網段的OSPF
R1:
router ospf 1
network 10.1.100.1 0.0.0.0 area 0
network 10.1.200.0 0.0.0.255 area 0
R2:
router ospf 1
network 10.1.100.0 0.0.0.255 area 0
network 10.1.200.0 0.0.0.255 area 0
R3:
router ospf 1
network 10.1.200.0 0.0.0.255 area 0
3. Loopback interface跑OSPF
R1:
router ospf 1
network 10.1.1.0 0.0.0.255 area 0
R2:
router ospf 1
network 10.1.2.0 0.0.0.255 area 0
R3:
router ospf 1
network 10.1.3.0 0.0.0.255 area 0
4. R1-3改變OSPF link cost
R1-3:
interface fastEthernet 0/0
ip ospf cost 50
5. 驗證指令
show ip ospf neighbor
show ip ospf interface
ping
R1設定檔:
hostname R1
!
no ip domain lookup
!
interface Loopback1
ip address 10.1.1.1 255.255.255.0
!
interface FastEthernet0/0
ip address 10.1.200.1 255.255.255.0
ip ospf cost 50
duplex auto
speed auto
!
interface Serial1/0
ip address 10.1.100.1 255.255.255.0
!
router ospf 1
network 10.1.1.0 0.0.0.255 area 0
network 10.1.100.1 0.0.0.0 area 0
network 10.1.200.0 0.0.0.255 area 0
!
line con 0
logging synchronous
!
end
R2設定檔:
hostname R2
!
no ip domain lookup
!
interface Loopback2
ip address 10.1.2.1 255.255.255.0
!
interface FastEthernet0/0
ip address 10.1.200.2 255.255.255.0
ip ospf cost 50
duplex auto
speed auto
!
interface Serial1/0
ip address 10.1.100.2 255.255.255.0
!
router ospf 1
network 10.1.2.0 0.0.0.255 area 0
network 10.1.100.0 0.0.0.255 area 0
network 10.1.200.0 0.0.0.255 area 0
!
line con 0
logging synchronous
!
end
R3設定檔:
hostname R3
!
no ip domain lookup
!
interface Loopback3
ip address 10.1.3.1 255.255.255.0
!
interface FastEthernet0/0
ip address 10.1.200.3 255.255.255.0
ip ospf cost 50
duplex auto
speed auto
!
router ospf 1
network 10.1.3.0 0.0.0.255 area 0
network 10.1.200.0 0.0.0.255 area 0
