no route to the destination is found in the routing table, the packet is discarded. Only direct-attached routing information is default in the routing table Basic elements of the routing table: Target network number Next-hop address to destination (direct-attached neighbor address) Out interf

protocol used by this file transfer process is called the FTP protocol. File transfer in FTP establishes two TCP connections, respectively, to the control connection to use when sending a transmission request and to the data connection that is used when the data is actually transferred. Remote login (telnet and SSH) is a feature that logs on to a remote computer and enables programs on that computer to run. Remote logins commonly used telnet and ssh two kinds of

1. Routing principleWhen data is transmitted over a network, it is necessary to query the local routing table and then decide whether to send the packet to the switch for frame exchange or direct to the router for IP addressing, depending on the routing table. First, different data in the transport layer according to different

The reason why routers can run normally is the result of a lot of different protocols working together, why can the protocols coexist without affecting each other? This is what the following is about, the concepts of routing protocols running. VRF: One of the security initiatives of

routing information to other routing information.2) measure valueDifferent routing protocols use different metrics, and sometimes multiple measures are used.? Hops : hop count metric can simply record the hop count of the router.? Bandwidth: The bandwidth (Bandwidth) metric will select a high-bandwidth path rather tha

In terms of network equipment maintenance, many maintenance documents now refer to the terms "routing policy" and "Policy Routing, however, many maintenance technicians do not have a thorough understanding of these two terms and cannot grasp the relationship and difference between them accurately. This article briefly analyzes the concepts between the two and introduces some examples. I hope you can get a d

in the IP data packet and the route table to route the IP data packet. 3. application Layer Protocol address: This is related to the specific application layer protocol. Different Application layer protocols have different addresses. For example, the HTTP protocol uses domain names as the routing address; the SMTP protocol uses username @ domain as the routing a

In the network, we usually use routers to allocate IP addresses. In the network protocol, the protocol that regulates the routing status is the routing selection protocol. Now let's take a look at the specific content of the routing protocol. First, let's take a look at its basic concepts and definitions. The routing s

provide this widely used Protocol. When the communication between the adjacent routers has been notified of the network connected by each of the other routers, a dynamic route is selected. Vrouters must communicate with each other using the routing protocol. There are many such routing protocols. A process on a vro。 becomes a

With the development of China's routing industry, it also promotes the continuous improvement of dynamic routing protocols. Here we mainly introduce the dynamic routing protocol used in network communication, computer networks) it is a complex system with many technologies, and each technology plays an irreplaceable ro

We all know that the destination address can be effectively selected for data distribution when the routing selection protocol is used. So how can we allocate resources when multiple protocols coexist? Now let's talk about this issue. I. Redistribution 1. Redistribution means that when an organization runs multiple routing pr
