上一篇：OSPF接口信息及中继列表
OSPF的链路状态数据库的路由链路状态信息
更加详细的描述R1路由器的链路状态数据库中每一个学习到的路由信息的具体状态信息。
R1#sh ip ospf database router 查询OSPF的链路状态数据库的路由链路状态信息
OSPF Router with ID (1.1.1.1) (Process ID 100)
路由ID是1.1.1.1，进程ID是100
Router Link States (Area 0)
LS age: 1320 链路状态的老化是1320
Options: (No TOS-capability, DC)
LS Type: Router Links 链路类型是路由链路
Link State ID: 1.1.1.1 链路状态ID是1.1.1.1
Advertising Router: 1.1.1.1 路由的ID是1.1.1.1
LS Seq Number: 80000007 链路状态的标识符
