注意其中没有使用汇总，直接把每个c类的网络加了进去。
拿172.30.152.0、24举例子：
interface vlan 20
ip address 172.30.152.253 255.255.255.0
no shutdown
set port vlan ge.2.14 20
set port vlan ge.2.15 20
set port vlan ge.2.16 20
set port vlan ge.2.17 20
set port vlan ge.2.18 20
set port vlan ge.2.19 20
set port vlan ge.2.20 20
set port vlan ge.2.21 20
set port vlan ge.2.22 20
set port vlan ge.2.23 20
set port vlan ge.2.24 20
set port vlan ge.2.25 20
set port vlan ge.2.26 20
set port vlan ge.2.27 20
set port vlan ge.2.28 20
set port vlan ge.2.29 20
set port vlan ge.2.30 20
set port vlan ge.2.31 20
set port vlan ge.2.32 20
set port vlan ge.2.33 20
set port vlan ge.2.34 20
set port vlan ge.2.35 20
set port vlan ge.2.36 20
set port vlan ge.2.37 20
set port vlan ge.2.38 20
set port vlan ge.2.39 20
set port vlan ge.2.40 20

那么，当ge.2.40被人为的关闭交换机的时候，n7.14汇聚交换机的ospf进程就会产生一个变化：172.30.152.0不可达。并且通告给核心。
而核心上就会产生路由变化：
O 172.30.152.0/24 [110/20] via 172.26.3.4, Vlan 301
这一条路由就会消失
OSPF重新计算期间就会占用CPU。
