ip add 10.10.2.2 255.255.255.0
exit
int f0/0
no shu

exit
r3:enable

exit
int l 0
ip add 10.10.4.4 255.255.255.0
exit
配置ospf
r1：router os 1
router-id 1.1.1.1
net 192.168.12.0 0.0.0.255 ar 12
net 10.10.1.0 0.0.0.255 ar 12
exit
r2:router os 1
router-id 2.2.2.2
net 192.168.12.0 0.0.0.255 ar 12
net 192.168.23.0 0.0.0.255 ar 0
net 10.10.2.0 0.0.0.255 ar 0
exit
r3:router os 1
router-id 3.3.3.3

net 10.10.4.0 0.0.0.255 ar 0
exit
做3類彙總思路先在r1作幾個直連路由，在r2做彙總，在其他路由
做驗證r1：
int l 11
ip add 11.11.1.1 255.255.255.0
exit
int l 12
ip add 11.11.2.2 255.255.255.0
exit
int l 13
ip add 11.11.3.3 255.255.255.0
exit
router os 1
router-id 1.1.1.1
net 11.11.1.0 0.0.0.255 ar 12
net 11.11.2.0 0.0.0.255 ar 12
net 11.11.3.0 0.0.0.255 ar 12
exit
clear ip os p
yshow ip route
show ip os da
r2:router os 1
area 12 range 11.11.0.0 255.255.0.0 (把12區域的11.11的各
個網段彙總為11.11.0.0網段)
exit
clear ip os p
yshow ip route
show ip os da
r3:clear ip os p
yshow ip route
show ip os da
show ip os
r4:clear ip os p
yshow ip route
show ip os da
show ip os
show ip route os
做5類的彙總思路，先在r1做幾個直連路由，靜態重分發，做5類
lsa，在r1做會總，在其他路由驗證
r1：int l 21
ip add 22.22.1.1 255.255.255.0
exit
int l 22
ip add 22.22.2.2 255.255.255.0
exit
int l 23
ip add 22.222.3.3 255.255.255.0
exit
router os 1
redistribute connected subnets (靜態重分發，建5類lsa)
exit
router os 1
summary-address 22.22.0.0 255.255.0.0
exit
clear ip os p
yshow ip route
show ip os
show ip os da
r2:clear ip os p
yshow ip route
show ip os da
r3:clear ip os p
yshow ip rute os
show ip os da
r4:clear ip os p
yshow ip rute os
show ip os da

lsa五類 OSPF五類LSA型別詳解
實驗拓撲 簡單說明 cisco和華為的管理距離不同，當然配置也不可能相同 cisco 110huawei 10 華為通過ospf學習到的路由為內部路由器，值是10，在ospf程序裡引入rip路由，外部路由器的話，150 ospf在內部無環，但是當然不可能是不出環的，不出環是不可能的，出環那麼好玩，是...
OSPF及一類LSA 二類LSA
ospf 鏈路狀態行協議 距離向量型和鏈路狀態型的區別 距離向量型 分布式計算 路由傳遞的計算都包含前乙個路由器計算的基礎。好處 減少計算量可以達到快速收斂的目的。壞處 前乙個計算錯誤會出現問題可靠性低，在傳遞過程中會將不優的丟棄 鏈路狀態型 先傳遞資訊沿途路由器不會進行加工。會收到全網的鏈路狀態形...
