are multiple network interconnection methods, among which the most commonly used are bridge interconnection and router interconnection.1.1 network connected by bridges The second layer in the OSI model, that is, the link layer. Complete data frame) forwarding, the main purpose is to provide transparent communication between Connected Networks. Bridge Forwarding is based on the source address and destination address in the data frame to determine whet

With the development of China's routing industry, it has also promoted the continuous improvement of router protocols. Here we mainly introduce the knowledge of router protocols that network engineers should have mastered. Distance Vector router protocols are designed for small network environments. In a large network environment, this type of

Essential security commands for CISCO router initialization 1. Security Settings for vro Access Control 1. Strict control over the administrator who can access the vro. Record Filing is required for all maintenance tasks. Www.2cto.com 2. do not access the vro remotely. Even if you need to access the vro remotely, we recommend that you use the access control list and high-intensity password control. 3. Strictly control access to CON ports. Specific mea

Intra-Domain Routing, transmitted only in this region, does not pass through the ABR. 2. Each vro is generated. 3. including the direct connection neighbor of the vro and the information of the Direct Connection Network Link ID: router ID ADV

The OSPF protocol is very important for the use of Cisco routers. But how do I perform specific operations? The following article will give a detailed explanation. OSPF protocol operation: 1. the ROUTER that declares OSPF sends a HELLO message from all interfaces that start the OSPF protocol. The two routers share a Public Data Link and can negotiate with each other the parameters specified in their HELLO packets. Then they become neighbors Neighbor)2

CISCO PT Simulation Experiment (13) router RIP dynamic routing configurationExperimental Purpose :The configuration method of mastering RIP Dynamic route selection protocolMastering RIP routing descriptions in routing tablesFamiliar with the principle and process of Routing and Packet forwardingExperimental Background : The company is connected to the export router of the enterprise network through a

Early domestic ADSL line access are bridge mode, by ADSL modem and computer, in the computer to allocate fixed IP address, boot can access to the local terminal equipment into the Internet. However, when the user does not boot on the Internet, IP is not to be exploited, will cause the current increasingly scarce public network IP resources waste, so there has been a PPPoE dial-up ADSL access. PPPoE dial-up can enable the user on the power-on dial-up access to the local equipment, by the local e

Subnet Mask hardware basic Ethernet protocol Network Management A router is a bridge of a computer network and a core device connecting to an IP network. It can connect different networks, select data transmission routes, and block unauthorized access. Router configuration is not easy for beginners. Take the Cisco router as an example to introduce the ge

China's vro technology is developing rapidly, and technological standards are also being innovated. So I have studied the basic knowledge and principles of vro technology. I would like to share it with you here and hope it will be useful to you. Due to the continuous advancement of social informatization, people's demand for data communication is increasing. Since the launch of TCP/IP protocol clusters in the middle of 1970s, it has become a factual standard for network layer communication proto

corresponding to the MAC address in the table, copy the packet directly onto the port. Three-layer switch: three-layer switching technology is the technology of combining routing technology with Exchange technology. After the first data flow is routed, the it will generate a MAC address and IP address mapping table, when the same data flow through again, according to this table directly from the two layer through rather than again routing, thus eliminating the

eliminating the router routing and resulting in network delay, improve the efficiency of packet forwarding. Routers: Traditionally, routers work in the third layer of the OSI Seven layer protocol, whose main task is to receive packets from a network interface and, depending on the destination address contained therein, decide to forward to the next destination address. Therefore, the router must first find

The wireless router is the transmission media, this article from the author's own TP-LINKWR641G as an example, describes the specific operation steps of the wireless router configuration, and describes the WAN port settings and other issues. As we all know in the tutorial on setting wireless routers, wireless signals are the carrier of data transmission, which means that the stability of wireless networks i

There is no fixed standard for understanding the Wireless Router Protocol. Generally, the standard is IEEE 802.11g. Other content of the wireless router is described in detail later. In our contact, these standards have little impact on us. Wireless Router Protocol Standard Currently, wireless routers support the IEEE 802.11g Wireless

When we use the Router device for networking, once encountered similar router device panic, the network is frequently dropped phenomenon, we can consider the router upgrade in order to timely fix the router system itself bugs, to ensure that the efficiency of the router more

Basic all routers on the shell will have a product nameplate, the above will be detailed labeling router login address, login account and password, the purchase of new router friends will often ask small knitting router login address, account number password, in fact, is in the immediate, but we are not good at observation, the following figure, We can see the Fi

The routing technology must also comply with the router standard in its application. Although the current router standard is not complete yet, it is believed that with the development of routing, it will also be more improved and stable. Vro supports multiple protocols, such as TCP/IP, IPX, SPX, and AppleTalk. Even the TCP/IP protocol has versions 4 and 6. However, due to the fact that TCP/IP has become a s
