【OSPF】基础配置案例

2026-09-27T05:09:00+08:00
OSPF基础配置实例配置简单基础案例如图 有R1、R2、R3 要求使用OSPF 使得R1的1.1.1.1与R3的3.3.3.3互通配置接口#配置R1接口
[R1]int GigabitEthernet 0/0/0
[R1-GigabitEthernet0/0/0]dis this
[V200R003C00]
#
interface GigabitEthernet0/0/0
ip address 10.0.1.254 255.255.255.0
#
return
[R1-GigabitEthernet0/0/0]q
[R1]int LoopBack 0
[R1-LoopBack0]dis this
[V200R003C00]
#
interface LoopBack0
ip address 1.1.1.1 255.255.255.0
#
return
[R1-LoopBack0]
#配置R2接口
[R2]int GigabitEthernet 0/0/0
[R2-GigabitEthernet0/0/0]dis this
[V200R003C00]
#
interface GigabitEthernet0/0/0
ip address 10.0.1.1 255.255.255.0
#
return
[R2-GigabitEthernet0/0/0]q
[R2]int GigabitEthernet 0/0/1
[R2-GigabitEthernet0/0/1]dis this
[V200R003C00]
#
interface GigabitEthernet0/0/1
ip address 10.0.2.1 255.255.255.0
#
return
[R2-GigabitEthernet0/0/1]
#配置R3接口
[R3]int GigabitEthernet 0/0/0
[R3-GigabitEthernet0/0/0]dis this
[V200R003C00]
#
interface GigabitEthernet0/0/0
ip address 10.0.2.254 255.255.255.0
#
return
[R3-GigabitEthernet0/0/0]q
[R3]int LoopBack 0
[R3-LoopBack0]dis this
[V200R003C00]
#
interface LoopBack0
ip address 3.3.3.3 255.255.255.0
#
return
[R3-LoopBack0]配置OSPF#配置R1 OSPF协议
[R1]ospf 1
[R1-ospf-1]dis this
[V200R003C00]
#
ospf 1 router-id 1.1.1.1
area 0.0.0.0
network 1.1.1.1 0.0.0.0
network 10.0.1.0 0.0.0.255
#
return
[R1-ospf-1]
#配置R2 OSPF协议
[R2]ospf 1
[R2-ospf-1]dis this
[V200R003C00]
#
ospf 1 router-id 2.2.2.2
area 0.0.0.0
network 10.0.1.0 0.0.0.255
area 0.0.0.1
network 10.0.2.0 0.0.0.255
#
return
[R2-ospf-1]
#配置R3 OSPF协议
[R3]ospf 1
[R3-ospf-1]dis this
[V200R003C00]
#
ospf 1 router-id 3.3.3.3
area 0.0.0.1
network 3.3.3.3 0.0.0.0
network 10.0.2.0 0.0.0.255
#
return
[R3-ospf-1]此时配置完成后 会有相关提示 最终有Full 代表邻居建立完成结果验证在路由器R2上查看OSPF邻居表 最终状态为Full 代表成功[R2]dis ospf peer brief

<R1> system-view
[R1] ospf 1
[R1-ospf-1] area 0.0.0.0
[R1-ospf-1-area-0.0.0.0] network 10.10.10.0 0.0.0.255 <-- 宣告新网段
[R1-ospf-1-area-0.0.0.0] quit
[R1-ospf-1] quit
在 R3 上操作:
<R3> system-view
[R3] ospf 1
[R3-ospf-1] area 0.0.0.1 <-- 注意:R3 之前配置的是 Area 1
[R3-ospf-1-area-0.0.0.1] network 30.30.30.0 0.0.0.255 <-- 宣告新网段
[R3-ospf-1-area-0.0.0.1] quit
[R3-ospf-1] quit
注意:R2 不需要宣告 10.10.10.0 或 30.30.30.0,它只负责中转测试结果:
<R1>ping -a 10.10.10.10 30.30.30.30

华为交换机的学习文档(持续更新)
https://xiongan.host/index.php/archives/231/
2024-05-21T04:44:59+08:00
基础配置如何配置端口镜像//将交换机连接监控设备的端口配置观察端口
//例如,将监控设备的端口GE0/0/20配置成观察端口
[SWA]observe-port 1 int g0/0/20
//将待镜像的报文流经的端口设置镜像端口,将这个端口需要镜像的方向,即接受或发送报文的方向绑定到观察端口
//将连接下游主机的端口GE0/0/7配置成镜像端口
[SWA]int g0/0/7
[SWA]port-mirroring to observe-port 1 inbound配置如上后,就可以在监控设备上启用监控软件,获取镜像报文

华为S系列的交换机Telnet登录
https://xiongan.host/index.php/archives/230/
2024-04-06T07:47:35+08:00
通过telent登录交换机应用场景:两台物理交换机(同段)之间的telnet访问 SW2 可以 以AAA验证方式登录到SW1的VRP系统已经配置好了交换机的vlanif 2端口ip (两台都在同段)具体配置配置Telnet登录所用的VTY用户界面的终端属性,指定VTY 0\~4这5条VTY虚拟通道可以用于登录[SW1]user-interface vty 0 4
[SW1-ui-vty0-4]idle-timeout 20 //设置超时间为20分钟
[SW1-ui-vty0-4]history-command max-size 20 //设置历史命令缓冲区的大小为20配置Telnet登录VTY用户界面的AAA验证方式和用户类别[SW1-ui-vty0-4]authentication-mode aaa
[SW1-ui-vty0-4]user privilege level 15
[SW1-ui-vty0-4]q配置控制通过Telnet访问交换机的用户ACL策略[SW1]user-interface maximum-vty 5 //设置VTY用户界面的最大个数
[SW1]acl 2001
[SW1-acl-basic-2001]rule permit source xxx //配置仅允许IP地址xx的主机访问
[SW1-acl-basic-2001]q
[SW1]user-interface vty 0 4
[SW1-ui-vty0-4]acl 2001 inbound //在VTY 0-4这5个用户界面中应用上面的ACL创建用于Telnet登录AAA验证的用户名和密码[SW1]aaa
[SW1-aaa]local-user huawei password cipher hello@123 //设置用户密码
[SW1-aaa]local-user huawei service-type telnet //设置该用户的服务类型为telnet
[SW1-aaa]local-user huawei privilege level 15 //生效级别设置的15开启Telnet服务器功能,并设置端口[SW1]telnet server enable
[SW1]telnet server port 1028测试结果查看,在SW2测试telnet交换机SW1

【OpenDaylight】及Postman实现流表下发

2023-04-14T00:25:00+08:00
安装OVS主机名ip角色ovs192.168.123.10ovs首先连接SSH用finalshell连接,需要提前配置好ip和网卡上传ovs源文件,并解压进入目录,执行./configure,生成Makefile文件然后进入编译安装make
make install实验六-OpenDaylight及Postman实现流表下发使用Opendaylight虚拟机安装jdk1.8,并启动opendaylight安装组件:首先清理旧数据DELETE http://127.0.0.1:8181/restconf/config/opendaylight-inventory:nodes/node/openflow:1/然后CLI命令行里再次清理sudo mn -c生成拓扑并连接 OpenDaylightsudo mn --topo=single,3 --controller=remote,ip=本机ip,port=6633 --switch ovsk,protocols=OpenFlow13使用 Postman 填入 JSON 格式的 http 请求//以下内容是Body中需要填写的

]
}现在CLI中h1 ping h3,再去PUT数据链接测试成功,结果符合预期鸣谢:小桂哥,King
