How Huawei routers configure static routes

The experiment purpose
Use static routing to make IP Data reachable
The topology

The experimental steps
1： Rename and configure IP Address
system-view
[Huawei]sysname R1 [R1]interface Ethernet 0/0/0
[R1-Ethernet0/0/0]ip address 12.1.1.1 255.255.255.0
[R1-Ethernet0/0/0]undo shutdown
system-view
[Huawei]sysname R2
[R2]interface Ethernet 0/0/0
[R2-Ethernet0/0/0]ip address 12.1.1.2 255.255.255.0
[R2-Ethernet0/0/0]undo shutdown
[R2]interface Ethernet 0/0/1
[R2-Ethernet0/0/1]ip add
[R2-Ethernet0/0/1]ip address 23.1.1.2 255.255.255.0
[R2-Ethernet0/0/1]undo shutdown
[Huawei]sysname R3
[R3-Ethernet0/0/0]ip address 23.1.1.3 255.255.255.0
[R3-Ethernet0/0/0]undo shutdown

2： In the middle router R2 Test whether the direct connection is connected
[R2-Ethernet0/0/1]ping 12.1.1.1
PING 12.1.1.1: 56 data bytes, press CTRL_C to break
Reply from 12.1.1.1: bytes=56 Sequence=1 ttl=255 time=160 ms Reply from 12.1.1.1: bytes=56 Sequence=2 ttl=255 time=20 ms Reply from 12.1.1.1: bytes=56 Sequence=3 ttl=255 time=10 ms Reply from 12.1.1.1: bytes=56 Sequence=4 ttl=255 time=30 ms Reply from 12.1.1.1: bytes=56 Sequence=5 ttl=255 time=40 ms

— 12.1.1.1 ping statistics — 5 packet(s) transmitted
5 packet(s) received
0.00% packet loss
round-trip min/avg/max = 10/52/160 ms
[R2-Ethernet0/0/1]ping 23.1.1.3
PING 23.1.1.3: 56 data bytes, press CTRL_C to break

Reply from 23.1.1.3: bytes=56 Sequence=1 ttl=255 time=50 ms Reply from 23.1.1.3: bytes=56 Sequence=2 ttl=255 time=50 ms Reply from 23.1.1.3: bytes=56 Sequence=3 ttl=255 time=50 ms Reply from 23.1.1.3: bytes=56 Sequence=4 ttl=255 time=30 ms Reply from 23.1.1.3: bytes=56 Sequence=5 ttl=255 time=30 ms

— 23.1.1.3 ping statistics — 5 packet(s) transmitted
5 packet(s) received
0.00% packet loss
round-trip min/avg/max = 30/42/50 ms

3： stay R1 Go straight ping R3 Will not work , You need to configure an authentication route in the direction of going and returning
[R1-Ethernet0/0/0]ping 23.1.1.3
PING 23.1.1.3: 56 data bytes, press CTRL_C to break Request time out
stay R1 And R3 Configure default routes respectively on ：
[R1]ip route-static 23.1.1.0 255.255.255.0 12.1.1.2
[R3]ip route-static 12.1.1.0 255.255.255.0 23.1.1.2

4： Then test connectivity ：
[R1]ping 23.1.1.3
PING 23.1.1.3: 56 data bytes, press CTRL_C to break
Reply from 23.1.1.3: bytes=56 Sequence=1 ttl=254 time=80 ms Reply from 23.1.1.3: bytes=56 Sequence=2 ttl=254 time=70 ms Reply from 23.1.1.3: bytes=56 Sequence=3 ttl=254 time=60 ms Reply from 23.1.1.3: bytes=56 Sequence=4 ttl=254 time=40 ms Reply from 23.1.1.3: bytes=56 Sequence=5 ttl=254 time=50 ms

— 23.1.1.3 ping statistics — 5 packet(s) transmitted
5 packet(s) received
0.00% packet loss
round-trip min/avg/max = 40/60/80 ms
// The above indicates successful communication .

4： It can also set priority for a static routing device , That is to say CISCO Management distance in （AD value ）, To achieve floating routing and other effects . as follows ：
[R1]ip route-static 23.1.1.0 255.255.255.0 12.1.1.2 preference 10

Please refer to NA My lab manual , Combined with Huawei's orders here , Realize floating static on Huawei's router , Select static , Summarize static , Default static , Static and other effects of load balancing .

View routing table ：
[R1]display ip routing
Route Flags: R - relay, D - download to fib

Routing Tables: Public
Destinations : 5 Routes : 5
Destination/Mask Proto Pre Cost Flags NextHop Interface 12.1.1.0/24 Direct 0 0 D 12.1.1.1 Ethernet0/0/0
12.1.1.1/32 Direct 0 0 D 127.0.0.1 Ethernet0/0/0
23.1.1.0/24 Static 10 0 RD 12.1.1.2 Ethernet0/0/0

127.0.0.1/32 Direct 0 0 D 127.0.0.1 InLoopBack0
5： When you want to cancel this default route , Play in front UNDO
[R1]undo ip route-static 23.1.1.0 255.255.255.0 12.1.1.2 preference 10
