分析:
1.目前根据拓补,我们配置好OSPF的区域.很快发现,AS2无法学习到AS 0里的路由.为此,我们需要为AS2通往AS 0建条路,当然这条路是需要经过AS1的,所以,虚电路就在AS1上进行.本实例其实就是一个命令的使用.为日后实验打下基础.有关OSPF内容,我将专门记载.
建立虚电路命令:
Area 经过的区域 virtual-link 目标路由ID
R1#show run
interface Loopback1
ip address 192.168.1.1 255.255.255.0
!
interface Loopback2
ip address 192.168.2.1 255.255.255.0
!
interface Serial1/1
ip address 12.0.0.1 255.255.255.252
serial restart-delay 0

验证:(主干区域拥有的是常规区域的汇总路由,常规区域拥用的是主干区域的精确通由.)
