This blog post will introduce in detail the problem of the adjacent relationship caused by inconsistent MTU and the solution. 1. MTU inconsistency (1) When to pay attention to MTU Starting from the Exstart status, the OSPF process follows the Interface MTU field in the DD message from the neighbor. (2) When to ignore

The first thing to look at is TCP/IP protocol, which involves four layers: link layer, network layer. Transport layer, application layer.The data frame of the Ethernet (Ethernet) in the link layerIP packets on the network layerTCP or UDP packets in the transport layerdata in TCP or UDP is in the application tierTheir relationship is the data frame {IP packet {TCP or UDP packet {data}}}---------------------------------------------------------------------------------The maximum length of data we u

In our commonly used Windows XP operating system, the default MTU value is 1500, which is a standard Ethernet setting value that is not suitable for broadband networks, whereas the MTU of General ADSL broadband is between 1450 and 1492, The discrepancy of the MTU between the system and ISP will directly result in the data in the network transmission process of co

Maximum Transmission Unit (MTU) refers to the Maximum data packet size (in bytes) that can be passed over a layer of a communication protocol ). The maximum transmission unit parameter is usually related to the communication interface (network interface card, serial port, etc ). The Internet Protocol allows IP sharding so that data packets can be divided into small fragments to pass through links with the maximum transmission unit smaller than the ori

MTU is the abbreviation of Maximumtransmissionunit, is the largest packet of packets on the network, most network device MTU is 1500,MTU unit is byte, if the MTU of the machine than the MTU of the gateway, large packets will be removed from the transmission, This will result

Most of the configuration parameters of zblog are in c_option.asp. A new version of zblog1.8 is downloaded, and c_option.asp is used to replace c_option.asp in the space. After logging in, you can log in; it seems that this file is a problem. For the new and old c_option.asp, the main content is mostly the same. The difference is only some parameters. Therefore, we guess, some parameters may affect the task volume during login. The latest version of zblog1.8 combines the "Update cache" function

MTU: Maximum Transmission unit of maxitum transmission unit MSS: maxitum Segment Size Maximum Segment Size Pppoe: PPP over Ethernet (carrying the PPP protocol over Ethernet) [Analysis process]Let's talk about the MTU's maximum transmission unit, which is closely related to the link layer protocol. Let's take a closer look at the structure of ethernetii frames DMAc + SMAC + Type + Data + CRC.Due to the electrical limitations of Ethernet transmission, e

MTU is the abbreviation of MaximumTransmissionUnit, which is the largest data packet transmitted over the network. MTU of most network devices is 1500, and MTU is measured in bytes. If the MTU of the local machine is larger than the MTU of the gateway, large data packets wil

Problems encountered a few days ago: the system may encounter problems when communication occurs, and the sending end will not report errors. However, the receiver does not respond. MTU details: Maximum Transmission Unit (MTU) refers to the maximum data size (in bytes) that can be passed on a layer of a communication protocol ). The maximum transmission unit parameter is usually related to the communica

The relationship between MSS and MTUTu:maximum transmission Unit, the maximum transmission unit, is specified by hardware, such as an Ethernet MTU of 1500 bytes.Mss:maximum segment size, the maximum section size, is the maximum data fragment size for each transmission of a TCP packet, typically by sending end-to-end TCP to notify the peer to the maximum TCP data that can be sent in each subsection. The MSS value is the

The neighbor state machine after the mtu value of the H3C OSPF interface has been studying the OSPF principle and configuration of H3C over the past few days. Now there are two routers R3 and R4 connected through their respective Ethernet ports E0/0, after configuring the IP address and OSPF correctly, modify the mtu value of the R3 E0/0 interface to 1000 (1500 by default) and restart the OSPF process of R3
