This article mainly introduces how to make clever configuration to make the router more convenient for us when we use the Huawei router. This article is of great help to the first contacts of the Huawei router.

Huawei routers and foreign brands of the same grade have completely the same functional features and configuration interface, and some aspects have also been well improved according to the needs of domestic users. For example, the configuration and debugging interface that can be switched between Chinese and English makes Chinese users no longer have to face a lot of professional English words. In addition, its software upgrade, remote configuration, backup center, PPP callback, and router Hot Backup are all very useful features for users.

In terms of configuration, the previous software versions of the Huawei router are slightly different from those of CISCO, but the current version is already compatible with CISCO. The following describes how to upgrade the VRP software, the configuration description is provided.

Upgrade VRP Software

Before the upgrade, you should understand the hardware configuration of your vro and the corresponding boot software bootrom version, because it is related to whether the upgrade can be performed and the upgrade method. Otherwise, the upgrade will fail and the vro will not run. Here, we will take the upgrade from VRP1.0 to VRP1.1 as an example to describe the upgrade method.

1. Configure the connection between one end of the router and the serial port of the PC and the console port of the router.
2. Create a Super Terminal using a direct connection under win95/98. The parameters are as follows:
Baud Rate 9600, data bit 8, stop bit 1, invalid verification, no traffic control, VT100 terminal type
3. After connecting to the Super Terminal, turn on the vro power. The Boot information appears on the screen:
Press Ctrl-B to enter Boot Menu.
Press Ctrl + B within three seconds, and the system will prompt you to enter the password.
Please input Bootrom password:

The default password is blank. Press enter to enter the Boot Menu. Select 1 under this Menu, that is, Download application program to upgrade the VRP software. Then, the screen prompts you to Select Download baud rate, we usually choose 38400 bps, and the prompt message is displayed:
Download speed is 38400 bps. Please change the terminal's speed to 38400 bps, and select XMODEM protocol. Press ENTER key when ready.

At this time, enter the "properties" of the Super Terminal and change the baud rate to 38400. After the modification, disconnect the Super Terminal and enter the connection status to make the new properties take effect. Then, the screen prompts: downloading... CCC

This indicates that the vro is in the waiting to receive file status. You can select the file "send" function of the Super Terminal, select the corresponding VRP software file name, and select Xmodem for the communication protocol, then the Super Terminal automatically sends the file to the vro, and the entire transfer process takes about 8 minutes and a half. After the configuration is completed, a message is displayed. The system writes the received VRP software to Flash Memory to overwrite the original system. The upgrade is completed, and the system prompts you to change the configuration to the baud rate of the Super Terminal:
Restore the terminal's speed to 9600 bps.
Press ENTER key when ready.

After the modification, remember to perform the disconnection and connection operations on the Super Terminal to make the new attributes take effect. Then, the vro software starts to start. Use the show ver command to view the corresponding version information.

Differences in the default link layer encapsulation (mainly used for DDN configuration)

1. in the configuration of Huawei VRP1.0 and earlier versions, the default link layer Encapsulation Format of CISCO is HDLC, while that of Huawei router is PPP, to change the Encapsulation Format of a CISCO router to the PPP format, run the following command:
Encapsulation PPP

2. The HDLC Encapsulation Format is added for Huawei VRP1.1 and later versions. In this way, the Encapsulation Format of the Huawei router is changed to the HDLC Encapsulation Format without changing the CISCO Encapsulation Format, that is, the command is used:
Encapsulation hdlc

Differences in X.25 Configuration

1. During configuration of Huawei VRP1.0 and earlier versions, CISCO X25 adopts its own standard Encapsulation Format by default. The encapsulation Format of the Huawei router is the international standard IETF. Therefore, in order to communicate with each other, you need to change the encapsulation Format of the CISCO router to the ietf format by using the command: encapsulation x25 ietf

2. Huawei VRP1.1 and later versions have specially added CISCO-compatible encapsulation formats. In this way, you do not need to change the CISCO Encapsulation Format, but change the X25 Encapsulation Format of the Huawei router to the CISCO Compatible Encapsulation Format, that is, use the command:
Encapsulation x25 cisco

Differences in Frame Relay Configuration

1. Huawei VRP1.0 and earlier versions, Because CISCO adopts the default FR Encapsulation Format as CISCO's own standard, and Huawei router Encapsulation Format as IETF standard. In addition, CISCO uses its own format by default in the configuration of the LMS (Frame Relay Local Management Information) type, while the Huawei router uses the Q.933a format. Therefore, in order to be interconnected, you need to change the FR Encapsulation Format of the CISCO router to IETF, and change the LMS format to Q.933a to communicate with each other. That is, you can use the following command:
Encapsulation frame-realy ietf
Frame-realy lm-type q933a

2. Huawei VRP1.1 and later versions specially added CISCO-compatible FR encapsulation formats and LMS formats. In this way, you do not need to change the CISCO encapsulation. Instead, you only need to change the FR Encapsulation Format and the RFC type of the Huawei router to the CISCO compatible format, that is, use the command:
Encapsulation frame-relay cisco
Frame-relay lm-type cisco
Note the preceding points when connecting Huawei and CISCO. If the CISCO User's link encapsulation is in its own format and the CISCO user does not want to modify the configuration, at the Huawei end, we must make corresponding changes.
