Full explanation of vro configurations

It is very useful to know some router configuration methods. So I have studied the detailed steps of router configuration. I will share them with you here, hoping to help you. The underlined bold text is the command you just typed. Make sure that your router configuration is correct, especially the password. If not, return to the configuration mode and enter the "no" + command. If the remote login password is incorrect, you must first enter the linear configuration mode to change the password, type "line vty 0 4" to enter the line router configuration mode of the remote login port.

If you do not enter "no" as the start word of the command, clear the command without "no. Some commands cannot be removed from the vro configuration file by using the prefix "no. If you do not want these commands to appear in the configuration file, set these commands to the default value. For example, the encapsulated HDLC command is set to the default value on the serial interface. If you set the Encapsulation Format to PPP peer protocol), you can only use "encaps hdlc" instead of "no encaps ppp ". You can try to delete the commands you typed and remember to enter them again before continuing learning.

If your vro configuration file is messy, enter "write erase" in the "Yun" prompt, press enter, and then press "y" to confirm that your deletion operation depends on the vro software version, you may be prompted to press enter to confirm ). What is the next step? Quot; reload ": If the vro asks whether to save the vro configuration file, press" n "to confirm the reload operation. The vro will return to the initial state. You can start from the new state.

After understanding the basic operations, we can start configuring the serial port R1. It must be noted that R1 is a standard part of the router framework. The R1 interface uses the <module number>/<port number> design. Vrouters of the 2500 series use a separate port number. This module number is available in the 3600, 4500/4700, and 2600 series. Before any interface changes, enter "show interface serial 1/1" at the r1's enable mode prompt. You can see that no IP address is assigned to this interface.

Enter "conf t" to enter the General router configuration mode, and enter "interface serial 1/1" to enter the router configuration mode interface. The default serial line uses the HDLC Encapsulation Format, which is more suitable for the interface here. All the IP addresses in this lab use a 24-byte subnet mask, 255.255.255.0. To assign an ip address to serial interface 1/1, type "ip address 10.1.5.1 255.255.255.0 ".

Our serial lines can run at a speed of 300 to 64 k bps, up to 2 Mbps ). Because we do not have DSU/CSU Data Service Unit/channel service unit in this interface) to view the running speed, we need to inform the router of the speed. Clock speed can only be set through the data communication device of the circuit terminal. We use a crossover serial cable, which allows one end to be connected as a data terminal device and the other end to be connected as a data communication device. Data communication devices for all serial cables end on R1 or Term_Srv (except R3 and R5, but we do not need ). That is to say, we need to set the clock speed for the serial port. Type "clock rate 64000" to set the clock rate to 64kps. By default, the left and right interfaces of Cisco are set to the drop-down management mode, which can prevent accidental operations. If not, type "no shutdown" to roll up the page. Type "end" to exit the vro configuration mode. Type "show interface serial 1/1" again to see the changes. It can be seen that the interface has been attached and an IP address has been allocated, but the thread protocol has not been attached to the volume, because the other end of the line has not ended.

We need to review the serial 1/0 interface in step 3. As shown in the layout chart, we need to repeat Step 3 using the IP address 10.1.4.1 and serial ports 1/0 and 10.1.4.1.
