ospf实验配置-2

OSPF的接口信息

OSPF接口状态信息，可以描述接口的各种OSPF时间参数，接口的网络类型和OSPF路由的具体信息。

R1#sh ip ospf interface 查询OSPF的接口信息 Serial1/0 is up, line protocol is up 接口是完全的UP 的

Internet Address 199.99.1.1/24, Area 0 接口地址在区域0中

Process ID 100, Router ID 1.1.1.1, Network Type POINT_TO_POINT, Cost: 64

进程ID是100，路由ID是1.1.1.1，网络类型是点对点，开销为64 Transmit Delay is 1 sec, State POINT_TO_POINT,

LSA通告从路由器接口发送后经历的时间，以Transmit Delay显示，缺省值为1sec

传输的延迟是1秒

Timer intervals configured, Hello 10, Dead 40, Wait 40, Retransmit 5

Hello的间隔时间为10秒，死亡时间为40秒，等待时间为40秒，中继为5

Hello due in 00:00:08 Hello的正当时间

Index 2/2, flood queue length 0 泛洪队列为0，证明不是广播模式

Next 0x0(0)/0x0(0)

Last flood scan length is 1, maximum is 1

Last flood scan time is 0 msec, maximum is 0 msec

Neighbor Count is 1, Adjacent neighbor count is 1 邻居只发现了一个

Adjacent with neighbor 2.2.2.2 邻居的ID

Suppress hello for 0 neighbor(s)

Loopback0 is up, line protocol is up 环回接口是UP

Internet Address 1.1.1.1/24, Area 0

Process ID 100, Router ID 1.1.1.1, Network Type LOOPBACK, Cost: 1

Loopback interface is treated as a stub Host 环回接口是一个标准的末节主机，含义是后面不会有任何网络设备。

OSPF的中继列表

R1#sh ip ospf retransmission-list 查询R1所连接的中继路由器

OSPF Router with ID (1.1.1.1) (Process ID 100)

Neighbor 2.2.2.2, interface Serial1/0 address 199.99.1.2 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
