我们现在要把区域 100 做成完全末节网络，来阻断 LSA3 类 在全局模式下用
rack02(config)#ipv router ospf 100 rack02(config-rtr)#ar
rack02(config-rtr)#area 100 st rack02(config-rtr)#area 100 stub n
rack02(config-rtr)#area 100 stub no-summary
R3 上
rack03(config)#router ospf 100 rack03(config-router)#ar
rack03(config-router)#area 100 st rack03(config-router)#area 100 stub
来看看 R3 的 路由表： rack03#sh ipv route
IPv6 Routing Table - 7 entries

rack03#ping 2000::1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2000::1, timeout is 2 seconds: !!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 64/96/176 ms rack03#ping 2002::1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2002::1, timeout is 2 seconds: !!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 28/52/120 ms
连通性也测试成功
