Reversal of multiplexing

With the development of the information age, digital lines are emerging and growing at an astonishing speed in data transmission media with many excellent features such as fast speed, stable performance, and reasonable prices, it has a dominant position. However, due to the technical reasons of the access device, the rental fee of the Digital Line cannot increase proportionally according to the actual bandwidth of the leased line, but is much higher than the actual bandwidth increase ratio. For example, the monthly rental fee of a 2 M Digital Line is 100000 Yuan/month. The monthly rental fee of a 8 M Digital Circuit at this price should be 400000 yuan/month, but it is actually quite different. In addition, because the price difference between 2 m photon panels and 8 m photon panels is large, many users are also discouraged. Furthermore, because the access capability of the line provider is limited, they may not be able to provide such bandwidth lines as 4 M and 8 M. Various situations indicate that the dial-out problem of large bandwidth lines has severely restricted users' demand for higher bandwidth.
The emergence of the problem will inevitably lead to corresponding solutions to the problem. One of the simplest and most direct methods is to use multiple low-bandwidth 2 M lines to meet the user's needs for high-bandwidth 8 M lines. However, new problems are born again. Theoretically, four 2 m lines equals one 8 m line, but in practical application, such a mathematical equation is not true. The problem must be solved by line multiplexing. However, the price of multiplead is eye-catching and is unacceptable to users.
The real problems are once again in front of us. We must find a different way to solve the problem, with the support of the technology network user Guangzhou Information Center, we finally found the answer in the router configuration: The Cisco router's "Inverse MUX Application using Multilink PPP" function provides us with the best way to solve this problem. Next we will use a simple example to further describe the usage of this function:
Routeconfig
Hostname roupid
Username RouterB password abc
Ip subnet-zero
Multilink virtual-template 1
!
Interface Virtual-Template1
Ip unnumbered Ethernet0
Ppp authentication chap

End
Through this method, we can combine multiple low-bandwidth lines into one line and transmit data through the Virtual port Virtual-Template 1. After configuring this method, we will find that when the port status sh interface is displayed, an additional port Virtual-Access 1 is displayed out of thin air, the data traffic on this port is equal to the total traffic on each actual port, and the data traffic is evenly allocated to each actual port. To merge low-bandwidth lines.
Note the following When configuring this function:
1. This function can only encapsulate the PPP protocol.
2. In interface virtual-template 1 configuration, ip unnumbered Ethernet0 can be replaced by ip address XXX.
