There are many things worth learning about in the PPP protocol. Here we will focus on the content of PPP frame relay. First, let's take a look at the basic concepts. PPP: Point-to-Point Protocol. Huawei routers are encapsulated by default and are character-oriented control protocols. HDLC: Advanced Data Link Control Protocol. It is a bit-Oriented Control Protocol and is the default encapsulation of Cisco routers. Fram-

We have introduced the configuration of the DHCP Server of the H3C switch. I wonder if you have a clear idea. Here, we will continue with the previous article to explain the content of the DHCP Relay configuration of the H3C switch. H3C switch DHCP Relay configuration 1> Configure Environment Parameters 1. the IP address of the DHCP Server is 192.168.0.10/24. 2. the DHCP Server is connected to port G1/1 of

Frame Relay WAN Protocol Configuration 1. Frame Relay is a high-performance WAN protocol, which runs on the physical layer and data link layer of the OSI reference model. It is a data packet exchange technology and a simplified version of X.25. It skips some strong functions of X.25, such as window technology and data re-transmission technology, but relies on high-level protocols to provide error correction

As the network scale expands, we will use the "Routing and Remote Access" function of the Windows server operating system to divide the network into different subnets. How can I provide services between two subnetworks through a DHCP server? In this case, you need to use the relay proxy function of the DHCP server to provide the DHCP service between two subnets at the same time. DHCP relay proxy configurati

I would like to introduce you to the method of the wireless router relay function. Many people may not understand the function of the wireless router relay function. It does not matter. After reading this article, you will certainly have a lot of GAINS to make your signal stronger. Use the wireless router relay function to improve network speed My Wireless Router

1 Introduction The structure of MPLSMultiprotocol Label Switching protocol is described in [1. A label exchange router can be used for Frame Relay switching. Frame relay switches the routing algorithms at the network layer, such as OSPF, IS-IS, and forward data based on these routing algorithms. You do not need to select a specific frame relay path.Frame

The 7th chapter deals with serial line and Frame Relay connection failuresI. Handling serial LINE faults1. HDLC EncapsulationHigh-level Data Link Control (HDLC) is a encapsulation method for a serial link, and HDLC is the default encapsulation method for the Cisco router serial interface.The first step in dealing with a serial link failure is to look at both ends of the link to use the same package type.Show interface serial 1; viewing interface infor

To manage networks more effectively, we use DHCP servers to manage a large number of IP addresses. So today we will focus on the content of DHCP Relay. We all know that both vswitches and vrouters can be used to establish DHCP servers. Next, we will introduce the DHCP Relay configuration. I hope this will help you. Functional requirements and networking description DHCP

DHCP relay principle and Configuration Application scenarios: When the number of hosts in a network is large, manual IP Address allocation is not only troublesome but also prone to errors. The emergence of the DHCP service greatly facilitates the allocation of Host IP addresses. Vlan division is an essential step in enterprise networking. How to enable a DHCP server to provide services for multiple CIDR blocks at the same time is what we will discuss

　　What does it mean to relay? In a literal sense, relaying refers to a relay station in between two lines that connects the two lines, like a road that is blocked by a large river, and the bridge erected in the middle is equivalent to a relay station. Professionally speaking, relay once we are mainly mentioned in the

In the main master or master copy, MySQL will generate the corresponding relay log under the home directory, this document summarizes the definition and explanation of these related parameters1. What is relay logThe relay log, like the binary log, consists of a set of numbered files containing events, describe database changes, and an index file, the contains the

The Windows Azure Service Bus allows a public connection point between the inside and outside of the Web service to connect internal and external services without changing the Enterprise Firewall or other security configurations. When using Azure cloud services, it is not scientific to use IP addresses to establish connections due to scaling. The relay service can act as a good public connection point. Of course, it is generally recommended to use a

Topology: R1 IP: 1.1.3.2/24 R2: analog relay switch R3 IP: 1.1.3.1/24 R2 (FR-SW) configuration is as follows: S1/0 Port: R2 (config) # frame-relay SwitchingR2 (config) # int S1/0R2 (config-If) # No IP AddressR2 (config-If) # encapsulation frame-relayR2 (config-If) # clock rate 64000R2 (config-If) # frame-relay LR-type?CiscoANSIQ933a R2 (config-If) # frame-

The setting of the wireless relay function not only protects our network, but also enables secure and fast wireless networks by simply making several changes. So how to set it? Which parameters should be modified to achieve this effect? For more information, see the following. In the previous article, we introduced the related wireless relay function settings. For details, refer to the article "how to confi

The content in dhcp relay configuration has been explained a lot. Next, let's explain two aspects: Configuring the dhcp relay dynamic user Address Table item regular refresh function and displaying and debugging dhcp relay. The specific content is as follows. ◆ Configure the dhcp relay dynamic user Address Table item

only wireless hotspot. Only at the same time do the client, and do wireless hotspot to meet the requirements of mobile phone to do FQ router. Is there any way to do it? The most straightforward approach is to use 3G Internet for mobile phones and then provide wireless hotspots out. This ability basically now all smartphones can do. But 3G Internet is much more expensive AH.Mobile phone can be connected to both uplink wireless, and open the wireless hotspot to share the environment to other devi

Frame Relay is a connection-oriented two-layer packet switching technology, the core idea is to use a unique DLCI (link identifier) number to build a virtual channel to the destination, when the packet is forwarded, through the DLCI to select the path. It is a network technology that differs from the two layer Mac switching technology and the three layer IP routing technology.Three basic terms:PVC: Permanent virtual link, virtual link is established p

We have learned about dhcp relay and explained in detail the setting of each function. Here we will introduce a dhcp relay configuration example to help you understand the content and deepen your impression. Let's take a look at these details. Dhcp relay configuration Example 1. Networking requirements The IP address range of the dhcp client is 10.110.0.0. The IP

We have introduced some articles about network security before. How should we set up the relay service in the device? Here we will provide a detailed answer. Of course, not all wireless devices can achieve the purpose of Wireless Network Relay Settings and amplification function, which requires the combination of powerful firmware program, the routing device used by the author has refreshed the DD-WRT V24 f

The network is always complex, so we can use DHCP servers to manage IP addresses well. Some DHCP relay functions are also involved. Here we will take a look at the Advanced content about DHCP relay. Use a DHCP server (PC version) across subnets ). To improve network security, a larger LAN is usually divided into multiple subnets. However, the DHCP server can only provide services for the machines in this su
