OSPF协议项目实战讲解-第一篇
1、要求按照下列标准配置一个OSPF网络
2、配置一个IP网络,实验逻辑图如图,IP地址见拓扑图
3、路由协议采用OSPF,进程ID为1 ,RID为loopback0地址
4、R1/R2/R3相连的三个站点链路OSPF网络类型配置成广播型,其中R1路由器做为永久性DR
5、按照图示配置OSPF区域,其中R2/R3/R4之间的区域要配置成完全末梢区域
6、R6为新并入的站点,由于来不及布线施工而暂时并到R5这个站点上,所在区域为AREA 56,配置使得所有网络可达(采用ping测试)
7、OSPF内部的网络希望通过R1路由器访问Internet,配置R1使其能够满足需求,只考虑内部路由器上路由的实现,不考虑NAT(下发默认路由)
8、AREA 0基于安全的原因配置上MD5认证,Key-ID为1,密码:Huawei
9、于R3与R4之间的链路质量较好,适当配置使得R4优先选取R3访问自身区域除外的外部网络
10、为了减少网络流量,R1只能学习到R6环回口的路由条目汇总条目(172.16.0.0/16)
1、要求按照下列标准配置一个OSPF网络
搭建拓扑图如下
2、配置一个IP网络,实验逻辑图如图,IP地址见拓扑图

检查
在R1上面检查如下
<R1>display ospf peer brief
OSPF Process 1 with Router ID 1.1.1.1

----------------------------------------------------------------------------
Area Id Interface Neighbor id State
0.0.0.0 GigabitEthernet0/0/0 2.2.2.2 Full
0.0.0.0 GigabitEthernet0/0/0 3.3.3.3 Full
----------------------------------------------------------------------------
在R2上面检查如下
<R2>display ospf peer brief
OSPF Process 1 with Router ID 2.2.2.2
Peer Statistic Information
----------------------------------------------------------------------------
Area Id Interface Neighbor id State
0.0.0.0 GigabitEthernet0/0/0 1.1.1.1 Full
0.0.0.0 GigabitEthernet0/0/0 3.3.3.3 2-Way
0.0.0.234 GigabitEthernet0/0/1 4.4.4.4 Full
----------------------------------------------------------------------------
因为R1为永久性DR,所以R2和R3是DROther
在R3上面检查如下
[R3]display ospf peer brief
OSPF Process 1 with Router ID 3.3.3.3
Peer Statistic Information
----------------------------------------------------------------------------
Area Id Interface Neighbor id State
0.0.0.0 GigabitEthernet0/0/0 1.1.1.1 Full

0.0.0.234 GigabitEthernet0/0/1 4.4.4.4 Full
----------------------------------------------------------------------------
在R4上面检查如下
<R4>display ospf peer brief
OSPF Process 1 with Router ID 4.4.4.4

----------------------------------------------------------------------------
Area Id Interface Neighbor id State
0.0.0.234 GigabitEthernet0/0/0 2.2.2.2 Full
0.0.0.234 GigabitEthernet0/0/1 3.3.3.3 Full
----------------------------------------------------------------------------
在R5上面检查如下
<R5>display ospf peer brief
OSPF Process 1 with Router ID 5.5.5.5
Peer Statistic Information
----------------------------------------------------------------------------
Area Id Interface Neighbor id State
0.0.0.35 GigabitEthernet0/0/0 3.3.3.3 Full
0.0.0.56 GigabitEthernet0/0/1 6.6.6.6 Full
----------------------------------------------------------------------------
在R6上面检查如下
<R6>display ospf peer brief
OSPF Process 1 with Router ID 6.6.6.6
Peer Statistic Information
----------------------------------------------------------------------------
Area Id Interface Neighbor id State
0.0.0.56 GigabitEthernet0/0/0 5.5.5.5 Full
----------------------------------------------------------------------------
此时发现R1 R2 R3 R4 R5之间都能够学习到各自的OSPF路由条目,R6由于没有按照正确的OSPF拓扑区域结构进行划分,导致R6不能够学习到任何其他设备的路由条目
4、R1/R2/R3相连的三个站点链路OSPF网络类型配置成广播型,其中R1路由器做为永久性DR
思路就是把R2和R3的接口优先级设置为0 OSPF的接口优先级的取值范围是0~255 当优先级为0的时候 代表本接口OSPF路由器不参与DR的选举,优先级为255就只代表优先级为255 这个和VRRP那个优先级要区分开来
#
interface GigabitEthernet0/0/0
ospf dr-priority 0
#
在R1上面查看DR
<R1>display ospf interface GigabitEthernet 0/0/0
OSPF Process 1 with Router ID 1.1.1.1

Designated Router: 192.168.123.1
Backup Designated Router: 0.0.0.0
Timers: Hello 10 , Dead 40 , Poll 120 , Retransmit 5 , Transmit Delay 1
5、按照图示配置OSPF区域,其中R2/R3/R4之间的区域要配置成完全末梢区域
R2的配置
#
ospf 1 router-id 2.2.2.2
area 0.0.0.234
stub no-summary
#
R3的配置
#
ospf 1 router-id 3.3.3.3

#
R4的配置
#
ospf 1 router-id 4.4.4.4

7、OSPF内部的网络希望通过R1路由器访问Internet,配置R1使其能够满足需求,只考虑内部路由器上路由的实现,不考虑NAT(下发默认路由)
在R1上面配置静态路由 然后下发其静态路由

8、AREA 0基于安全的原因配置上MD5认证,Key-ID为1,密码:Huawei
在R1的区域0中配置区域0的认证
#
ospf 1 router-id 1.1.1.1
area 0.0.0.0
authentication-mode md5 1 plain Huawei
#
在R2的区域0中配置区域0的认证
#
ospf 1 router-id 2.2.2.2
area 0.0.0.0
authentication-mode md5 1 plain Huawei
#
在R3的区域0中配置区域0的认证
#
ospf 1 router-id 3.3.3.3
area 0.0.0.0
authentication-mode md5 1 plain Huawei
#
在R5的区域0中配置区域0的认证
#
ospf 1 router-id 5.5.5.5
area 0.0.0.0
authentication-mode md5 1 plain Huawei
#
或者第二种方法:
#
ospf 1 router-id 5.5.5.5
area 0.0.0.0
area 0.0.0.35
network 5.5.5.5 0.0.0.0
network 192.168.35.0 0.0.0.255
vlink-peer 3.3.3.3 md5 1 plain Huawei 直接在后面接上认证的参数也是可以的
area 0.0.0.56
network 192.168.56.0 0.0.0.255
#
检查 看下 R5和R3之间的FULL关系是否正常
9、于R3与R4之间的链路质量较好,适当配置使得R4优先选取R3访问自身区域除外的外部网络
在R4的G0/0/0接口修改OSPF的开销值
[R4-GigabitEthernet0/0/0]dis this
[V200R003C00]
#
interface GigabitEthernet0/0/0
ip address 192.168.24.4 255.255.255.0
ospf cost 2

检查

10、为了减少网络流量,R1只能学习到R6环回口的路由条目汇总条目(172.16.0.0/16)
在R5的区域56当中进行路由汇总
#
ospf 1 router-id 5.5.5.5
area 0.0.0.56
abr-summary 172.16.0.0 255.255.0.0
#
return
检查如下
