　　目的：通过汇总减少路由器由于路由表中的路由条目过多产生的负担

　　路由器的基本配置：

r1#sho run ! interface Loopback0 ip address 199.172.16.1 255.255.255.0 ! interface Loopback1 ip address 199.172.17.1 255.255.255.0 ! interface Loopback2 ip address 199.172.18.1 255.255.255.0 ! interface Loopback3 ip address 199.172.19.1 255.255.255.0 ! interface FastEthernet0/0 ip address 12.0.0.1 255.255.255.0 duplex half ! router ospf 110 log-adjacency-changes network 0.0.0.0 255.255.255.255 area 12 ! !
