篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了必看!华为HCIA路由与交换实验配置大全相关的知识,希望对你有一定的参考价值。
ARP代理
实验:如下配置两台PC,要求实现两台PC的互相通信。
在这里插入图片描述
为PC各自配置IP,网关设置为G0/0/0口和G0/0/1接口的IP
配置AR3的接口IP,并开启相关的服务
[R1-GigabitEthernet0/0/0]undo info en //不会提示信息
[R1-GigabitEthernet0/0/0]arp-proxy enable //开启ARP代理
[R1-GigabitEthernet0/0/1]arp-proxy enable
[R1-GigabitEthernet0/0/1]dis ip int bri //查看所有的接口信息,检查IP地址是否配上以及接口是否双up
Interface IP Address/Mask Physical Protocol
GigabitEthernet0/0/0 192.168.10.254/24 up up
GigabitEthernet0/0/1 192.168.20.254/24 up up
[R1-GigabitEthernet0/0/1]dis arp all //查看ARP表项
####在PC上做连通性测试
可以通过配置网关实现互通,网关地址为路由器与PC接口的IP通过ARP代理实现互通,需要改变子网掩码使不同网段的IP处于同一网段,如本题中的可以将子网掩码修改为255.255.192.0,即可不通过网关实现互通
划分VLAN
实验:如下图配置PC的IP地址,需求相同VLAN可以互通,不同VLAN不能互通。
[SW1]dis vlan //查看VLAN
[SW1]vlan batch 10 20 //创建VLAN10、VLAN20
[SW1]int e0/0/2
[SW1-Ethernet0/0/2]port link-type access //设置接口类型为Access
[SW1-Ethernet0/0/2]port default vlan 10 //默认划分进VLAN10
同样方法配置e0/0/3接口,划分进VLAN 20
[SW1]int g0/0/1 //进入g0/0/1接口
[SW1-GigabitEthernet0/0/1]port link-type trunk //配置接口类型为Trunk
[SW1-GigabitEthernet0/0/1]port trunk allow-pass vlan 10 20 //设置允许通过的VLAN为10 20 ,VLAN1默认允许通过
#SW2相同的配置
#做连通性测试#同样方法配置e0/0/2接口port hybrid pvid vlan 10
port hybrid untagged vlan 10 30
#同样方法配置e0/0/2接口
#配置e0/0/4接口
port hybrid pvid vlan 30
port hybrid untagged vlan 10 20 30
#配置e/0/1接口
port hybrid tagged vlan 10 20 30
默认PVID是VLAN 1
#SW2同样的配置
#进行连通性测试
hybrid
按照如下拓扑,配置相关IP地址。需求:
- 不同楼层的HR部门和市场部门实现部门内部通信
- 两部门之间不允许通信
- IT部门可以访问任意部门
[SW1]dis vlan //查看是否创建
[SW1]int e0/0/3//进入e0/0/3接口
[SW1-Ethernet0/0/3]port hybrid untagged vlan 20 30 //设置允许通信的VLAN
[SW1-Ethernet0/0/3]port hybrid pvid vlan 20 //设置PVID
[SW1-Ethernet0/0/3]dis th //查看当前接口下的命令
[SW1]vlan batch 10 20 30 //创建VLAN10、20、30
port hybrid pvid vlan 10
port hybrid untagged vlan 10 30
#配置e0/0/4接口
port hybrid pvid vlan 30
port hybrid untagged vlan 10 20 30
#配置e/0/1接口
port hybrid tagged vlan 10 20 30
默认PVID是VLAN 1
#SW2同样的配置
#进行连通性测试
#同样方法配置e0/0/2接口
VLAN间路由
单臂路由
- 把PC划分到相应的VLAN
- 把g0/0/1接口配置成trunk,并允许所有VLAN通过
- 配置路由器的子接口配置IP地址
- 子接口配置VLAN ID封装(
dot1q termination vid 10
) - 接口开启arp广播(
arp broadcast enable
)
#先给PC配置相应的IP地址,网关254
[SW1]vlan batch 10 20 30 //创建VLAN
[SW1]dis vlan //查看VLAN是否创建成功
[SW1]int g0/0/2 //进入g0/0/2接口
[SW1-GigabitEthernet0/0/2]port link-type access //配置接口类型为access
[SW1-GigabitEthernet0/0/2]port default vlan 10 //划分默认VLAN
#同样的方法配置g0/0/3、g0/0/4接口
#配置trunk接口,并允许所有VLAN通过
[SW1]int g0/0/1
[SW1-GigabitEthernet0/0/1]port link-type trunk //配置接口类型为trunk
[SW1-GigabitEthernet0/0/1]port trunk all vlan all //允许所有VLAN通过
#在R1上配置子接口
[R1]int g0/0/0.1 //配置子接口
[R1-GigabitEthernet0/0/0.1]ip add 192.168.10.254 24 //为子接口配置IP
#同样方法配置其他子接口
[R1]dis ip int br //查看所有接口详细信息
#封装VLAN号
[R1]int g0/0/0.1
[R1-GigabitEthernet0/0/0.1]dot1q termination vid 10 //指定vid,即这个接口对应的VLAN ID
[R1-GigabitEthernet0/0/0.1]arp broadcast enable //开启ARP的广播功能
#同样方法配置其他的子接口
#进行连通性测试
三层交换
[SW1]int Vlanif 10 //创建VLAN10
[SW1-Vlanif10]ip add 192.168.10.254 24 //配置IP地址
[SW1-Vlanif10]int vlanif 20
[SW1-Vlanif20]ip add 192.168.20.254 24
[SW1-Vlanif20]int vlanif 30
[SW1-Vlanif30]ip add 192.168.30.254 24
#进行连通性测试

0 Ethernet0/0/3 ALTE DISCARDING NONE
# Ethernet0/0/1为RP,数据正常转发,Ethernet0/0/2和Ethernet0/0/3为AP,DISCARDING端口关闭,不转发数据
[SW4]dis stp bri //查看SW4的STP
MSTID Port Role STP State Protection
0 Ethernet0/0/1 ROOT FORWARDING NONE
0 Ethernet0/0/2 DESI FORWARDING NONE
拓展:使SW1为根桥,SW3位次根桥
[SW1]stp root primary //使SW1成为主根桥
[SW1]dis stp //查看cost优先级为0
[SW3]stp root secondary //使SW3成为次根桥
[SW3]dis stp //查看cost优先级为4096
增长为12次方增长,下一个是8192,一次类推

[SW1-Ethernet0/0/1]stp cost ? //修改接口开销

RIP配置

[R1]int LoopBack 1
[R1-LoopBack1]ip ad 1.1.1.1 24
[R1-LoopBack1]int g0/0/0
[R1-GigabitEthernet0/0/0]ip ad 12.1.1.1 24
相同方法配置其他路由器
配置RIP,对外宣告主网(宣告的为自身已知的主网)
[R1]rip 1
[R1-rip-1]network 1.0.0.0
[R1-rip-1]network 12.0.0.0
#相同方法配置其他路由器 连通性测试
RIP环路
- 网络发生故障时,RIP网络有可能会产生环路
- 环路避免:
- 水平分割:路由器从某个接口学到的路由,不会从该接口再发回给领居路由
- 毒性逆转:路由从某个接口学到路由后,将该路由的跳数设置为16,并从原接收接口发回给领居路由器
- 触发更新:当路由信息发生变化时,立即向邻居设备发送触发更新报文(避免环路产生)

# 配置RIP报文的收发

# 抑制接口,命令优先级大于rip in/output
