实验目的：比较ospf的5种网络类型，不同的ospf网络类型能否建立邻居？

实验拓扑：

接口如果是串口的话，默认的网络类型是点到点，然而接口如果是以太口的话，默认的网络类型是广播型网络。

R2#show ip ospf int s1/0

Serial1/0 is up, line protocol is up

Internet Address 10.1.1.2/24, Area 0

Process ID 1, Router ID 2.2.2.2, Network Type POINT_TO_POINT, Cost: 64

Transmit Delay is 1 sec, State POINT_TO_POINT,

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

oob-resync timeout 40

Hello due in 00:00:02

Index 2/2, flood queue length 0

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

Adjacent with neighbor 1.1.1.1

Suppress hello for 0 neighbor(s)

R3#show ip ospf int fa0/0

FastEthernet0/0 is up, line protocol is up
