简单介绍命令

以太网工作在数据链路层

数据的三要素：1.语法2.语义3.同步（接口速率）

mac-address 查看mac地址表

sysname R1 改名为R1

dis version 查看系统版本

interface gigabitethernet0/0/1 进入g0/0/1接口

ip- subnet-vlan 查看接口vlan网段信息

speed 10 接口速率配置为10M

undo negotiation auto 关闭自动协商

dis vlan 查看vlan接口分布表

int g0/0/0 进入g0/0/0 接口

ip add 192.168.1.1. 24 配置接口ip地址为192.168.1.1 子网掩码24位

undo shutdown 启用

pre 优先级

cost 花销值

浮动路由

即备份一条优先级比当前路由低的路由

实验名称：

实现三台路由器的loop 接口互联互通

配置各个路由器的接口ip就开始配置相应的路由条目

1.1.1.1 去ping 2.2.2.2，有两条路可走，分别是R1》》R2，和R1》》R3》》R2，可以分别配置，先配置的优先级最高，后配置的最备用，等待优先级高的路由失效后就会触发优先级低的路由，以免因为链路损坏而影响数据及时传输

同理，1.1.1.1ping3.3.3.3 也是同样的道理

2.2.2.2ping3.3.3.3也是

在这里详细解释1.1.1.1去ping2.2.2.2的过程，剩下的举一反三即可

R1》》R2

对于1.1.1.1而言，2.2.2.2是R1的非直连网段，所以数据过去的话需要去给R1配置一条2.2.2.0的静态路由，下一跳为12.0.0.2；数据回来就是从R2返回到R1，需要给R2配置一条1.1.1.0的静态路由，下一跳为12.0.0.1

R1》》R3》》R2

首先，值得注意的是，数据一来一回的优先级必须在同一链路上，不可以分开

R1的数据传到R2，经过R3，需要给R1配置一条2.2.2.0的条目，下一跳为13.0.0.3，因为这个条目是第二个配置，所以在12.0.0.0正常作用的情况下，第二个条目不会被触发，这里配置这一条目，仅作备用；2.2.2.0也并不是R3的直连网段，所以需要给R3配置一条2.2.2.0的静态路由，下一跳为23.0.0.2。数据过去了，也要回来，配置路由的思路跟过去的一致，这里就不赘述了，开始配置

3.开启设备，先配置ip

R1

R2的ip配置

R3的ip 配置

system-view '进入系统视图' Enter system view, return user view with Ctrl+Z. [Huawei]undo info-center enable '关掉信息中心' Info: Information center is disabled. [Huawei]sysname R3 '更名为R3' [R3]int g0/0/1 '进入g0/0/1接口' [R3-GigabitEthernet0/0/1]ip add 13.0.0.3 24 '配置ip信息' [R3-GigabitEthernet0/0/1]undo shutdown '启用' Info: Interface GigabitEthernet0/0/1 is not shutdown.

ip配置完毕，接下来就开始配置路由，先从1.1.1.1去ping 2.2.2.2的思路去配置

R1

system-view '进入系统视图' Enter system view, return user view with Ctrl+Z. [Huawei]sysname R1 '改名为R1' [R1] Nov 7 2019 19:45:23-08:00 R1 DS/4/DATASYNC_CFGCHANGE:OID 1.3.6.1.4.1.2011.5.25. 191.3.1 configurations have been changed. The current change number is 5, the ch ange loop count is 0, and the maximum number of records is 4095. '出现信息中心的信息' Info: Information center is disabled. '关掉信息中心' [R1]ip route-static 2.2.2.0 24 12.0.0.2 '配置静态路由，目标网段2.2.2.0，下一跳12.0.0.2'

R2

[R2]ip route-static 1.1.1.0 24 12.0.0.1 '配置静态路由，目标网段1.1.1.0 下一跳为12.0.0.1'

R1的1.1.1.1 去ping 2.2.2.2

[R1]ping -a 1.1.1.1 2.2.2.2 '-a指定源ip地址' PING 2.2.2.2: 56 data bytes, press CTRL_C to break Reply from 2.2.2.2: bytes=56 Sequence=1 ttl=255 time=50 ms '成功' Reply from 2.2.2.2: bytes=56 Sequence=2 ttl=255 time=20 ms Reply from 2.2.2.2: bytes=56 Sequence=3 ttl=255 time=50 ms Reply from 2.2.2.2: bytes=56 Sequence=4 ttl=255 time=30 ms Reply from 2.2.2.2: bytes=56 Sequence=5 ttl=255 time=20 ms --- 2.2.2.2 ping statistics --- 5 packet(s) transmitted 5 packet(s) received 0.00% packet loss round-trip min/avg/max = 20/34/50 ms

接下来配置备用路由，即R1》》R3》》R2

R1

[R1]ip route-static 2.2.2.0 24 13.0.0.3 '配置静态路由'

R3

[R3]ip route-static 2.2.2.0 24 23.0.0.2 '配置静态路由'

再往回配

R2

[R2]ip route-static 1.1.1.0 24 23.0.0.3

R3

[R3]ip route-static 1.1.1.0 24 13.0.0.1

接下来可以把12.0.0.0/24的链路中断

[R1]int g0/0/0 '进入对应网段接口' [R1-GigabitEthernet0/0/0]shutdown '关闭' [R1-GigabitEthernet0/0/0]q

这个时候再ping一波

[R1]ping -a 1.1.1.1 2.2.2.2 PING 2.2.2.2: 56 data bytes, press CTRL_C to break Reply from 2.2.2.2: bytes=56 Sequence=1 ttl=254 time=80 ms Reply from 2.2.2.2: bytes=56 Sequence=2 ttl=254 time=60 ms Reply from 2.2.2.2: bytes=56 Sequence=3 ttl=254 time=60 ms Reply from 2.2.2.2: bytes=56 Sequence=4 ttl=254 time=60 ms Reply from 2.2.2.2: bytes=56 Sequence=5 ttl=254 time=50 ms --- 2.2.2.2 ping statistics --- 5 packet(s) transmitted 5 packet(s) received 0.00% packet loss round-trip min/avg/max = 50/62/80 ms

查看一下此时R1的路由表

[R1]dis ip routing-table '查看路由表' Route Flags: R - relay, D - download to fib ------------------------------------------------------------------------------ Routing Tables: Public Destinations : 7 Routes : 7 Destination/Mask Proto Pre Cost Flags NextHop Interface 1.1.1.0/24 Direct 0 0 D 1.1.1.1 LoopBack0 1.1.1.1/32 Direct 0 0 D 127.0.0.1 LoopBack0 2.2.2.0/24 Static 60 0 RD 13.0.0.3 GigabitEthernet '注意这一条' 0/0/1 13.0.0.0/24 Direct 0 0 D 13.0.0.1 GigabitEthernet 0/0/1 13.0.0.1/32 Direct 0 0 D 127.0.0.1 GigabitEthernet 0/0/1 127.0.0.0/8 Direct 0 0 D 127.0.0.1 InLoopBack0 127.0.0.1/32 Direct 0 0 D 127.0.0.1 InLoopBack0

恢复12.0.0.1链路，再次查看路由表

[R1]int g0/0/0 [R1-GigabitEthernet0/0/0]undo shutdown [R1-GigabitEthernet0/0/0]q [R1]dis ip routing-table Route Flags: R - relay, D - download to fib ------------------------------------------------------------------------------ Routing Tables: Public Destinations : 9 Routes : 10 Destination/Mask Proto Pre Cost Flags NextHop Interface 1.1.1.0/24 Direct 0 0 D 1.1.1.1 LoopBack0 1.1.1.1/32 Direct 0 0 D 127.0.0.1 LoopBack0 2.2.2.0/24 Static 60 0 RD 12.0.0.2 GigabitEthernet '注意这一条' 0/0/0 Static 60 0 RD 13.0.0.3 GigabitEthernet 0/0/1 12.0.0.0/24 Direct 0 0 D 12.0.0.1 GigabitEthernet 0/0/0 12.0.0.1/32 Direct 0 0 D 127.0.0.1 GigabitEthernet 0/0/0 13.0.0.0/24 Direct 0 0 D 13.0.0.1 GigabitEthernet 0/0/1 13.0.0.1/32 Direct 0 0 D 127.0.0.1 GigabitEthernet 0/0/1 127.0.0.0/8 Direct 0 0 D 127.0.0.1 InLoopBack0 127.0.0.1/32 Direct 0 0 D 127.0.0.1 InLoopBack0

接下来就主要按部就班把其余的以同样的形式配置好即可

1.1.1.1 ping 3.3.3.3

R1

[R1]ip route-static 3.3.3.0 24 13.0.0.3

R3

[R3]ip route-static 2.2.2.0 24 23.0.0.2 Error: The route already exists.

再去配置另一条备用路由

R2》》R1》》R3

R2

[R2]ip route-static 3.3.3.0 24 12.0.0.1

R1

[R1]ip route-static 3.3.3.0 24 13.0.0.3 Error: The route already exists.

R1

[R1]ip route-static 2.2.2.0 24 12.0.0.2 Error: The route already exists.

完毕
