實驗說明:
1.在上面拓撲圖中,R1\R2\R3\R4四臺router分別設(shè)置三個loopback口(圖上畫不出來滴-_-|).
R1:171.16.1.1/24、171.16.2.1/24、171.16.3.1/24
R2: 172.16.1.1/24、172.16.2.1/24、172.16.3.1/24
R3: 173.16.1.1/24、173.16.2.1/24、173.16.3.1/24
R4: 174.16.1.1/24、174.16.2.1/24、174.16.3.1/24
2.在整個拓撲中,使用OSPF劃分成3個area:
area 0 : 171.16.0.0/22、10.10.10.0/24
area 1 : 172.16.0.0/22、20.20.20.0/24、173.16.0.0/22
area 2 : 174.16.0.0/22、192.168.1.0/24 30.30.30.0/24
實驗?zāi)康?
multiarea ospf + ospf route summrization + virtual link + ospf default route/static default route
(涉及到的知識點超級多滴!!嘿嘿~~~)
配置思路:
1.用multiarea OSPF把路由搞定先!!!
2.配置route summrization,將所有router上總共4個loopback匯總一下子。
3.分別使用三個方法將area 2的路由配通一遍:
a. OSPF virtual link
b. OSPF default route
c. ststic default route
4.最終驗證時在PC上ping全網(wǎng)可以通就OK... ^oo^
一、基本配置:

line vty 0 4
exec-timeout 0 0
logging syn
pass cisco
login
end

二、動態(tài)路由OSPF配置:
R1:
conf t
router ospf 1
network 10.10.10.0 0.0.0.255 area 0
network 171.16.1.0 0.0.0.255 area 0
network 171.16.2.0 0.0.0.255 area 0
network 171.16.3.0 0.0.0.255 area 0
network 171.16.4.0 0.0.0.255 area 0
end
R2:
conf t
router ospf 1
network 10.10.10.0 0.0.0.255 area 0
network 172.16.1.0 0.0.0.255 area 1
network 172.16.2.0 0.0.0.255 area 1
network 172.16.3.0 0.0.0.255 area 1
network 172.16.4.0 0.0.0.255 area 1
network 20.20.20.0 0.0.0.255 area 1
end
R3:
conf t
router ospf 1
network 20.20.20.0 0.0.0.255 area 1
network 173.16.1.0 0.0.0.255 area 1
network 173.16.2.0 0.0.0.255 area 1
network 173.16.3.0 0.0.0.255 area 1
network 173.16.4.0 0.0.0.255 area 1
network 30.30.30.0 0.0.0.255 area 2
end
#p#副標題#e#
R4:
conf t
router ospf 1
network 30.30.30.0 0.0.0.255 area 2
network 174.16.1.0 0.0.0.255 area 2
network 174.16.2.0 0.0.0.255 area 2
network 174.16.3.0 0.0.0.255 area 2
network 174.16.4.0 0.0.0.255 area 2
network 192.168.1.0 0.0.0.255 area 2
end
*********************************************************************
三、配通網(wǎng)絡(luò)的三種方法:
***************ospf virtual-link:***************
r2(ABR):
conf t
router ospf 1
area 1 virtual-link 173.16.4.1
r3(ABR):
conf t
router ospf 1
area 1 virtual-link 172.16.4.1
檢驗:
#sh ip ospf virtual-link
--------------------------------------------------------------------------------------------
***************ospf default route:***************
r3:
conf t
router ospf 3
default-information originate always
檢驗:
#sh ip route
#ping
--------------------------------------------------------------------------------------------
***************static default route:***************
r1:
conf t
ip route 0.0.0.0 0.0.0.0 10.10.10.2
r2:
conf t
ip route 0.0.0.0 0.0.0.0 20.20.20.2
r4:
conf t
ip route 0.0.0.0 0.0.0.0 30.30.30.1
=====================================================================
四、ospf route summarization
r2:(ABR)
conf t
router ospf 1
area 0 range 171.16.0.0 255.255.252.0
area 1 range 172.16.0.0 255.255.252.0
r3:(ASBR)
conf t
router ospf 1
summary-address 173.16.0.0 255.255.252.0
summary-ad
