Configuration Roadmap

The configuration roadmap is as follows:

If there is only one match for an incomplete keyword, enter the incomplete keyword and press Tab.
If there are several matches for an incomplete keyword, enter the incomplete keyword and press Tab repeatedly until the desired keyword is found.
Enter an incorrect keyword and press Tab. The incorrect keyword remains unchanged.

The use of Tab is described as follows:

Procedure

If There Is Only One Match for an Incomplete keyword
1. Enter an incomplete keyword.
```
[~HUAWEI] ip rout
```
2. Press Tabs.
  The system replaces the entered keyword with the complete keyword followed by a space.
```
[~HUAWEI] ip route-static
```

If There Are Several Matches for an Incomplete keyword

# The keyword ip route-static can be followed by the following keywords:

[~HUAWEI] ip route-static ?
  X.X.X.X             Destination IP address
  bfd                 BFD configuration information
  default-bfd         Default BFD parameter
  default-preference  Preference-value for IPv4 static-routes
...

Enter an incomplete keyword.
```
[~HUAWEI] ip route-static d
```
Press Tab.
The system first displays the prefixes of all the matched keywords. In this example, the prefix is default.
```
[~HUAWEI] ip route-static default-
```
Press Tab to switch from one matching keyword to another. The cursor closely follows the end of a word.
```
[~HUAWEI] ip route-static default-bfd
[*HUAWEI] ip route-static default-preference
```
Stop pressing Tab when the desired keyword is found.

Enter the value 10.

[~HUAWEI] ip route-static default-preference 10

If an Incorrect Keyword Is Entered
1. Enter an incorrect keyword.
```
[~HUAWEI] ip route-static default-pe
```
2. Press Tab.
  The system displays the output in a new line. The entered keyword remains unchanged.
```
[~HUAWEI] ip route-static default-pe
```
