The MTU is the abbreviation for Maximumtransmissionunit.
The maximum packet that is transmitted over a network. The unit of the MTU is bytes. Most network devices have an MTU of 1500. If the MTU of this machine is larger than the MTU of the gateway, large packets are remove

Www.baidu.com: Set Baidu as the detection target
(You asked me why I didn't use Google as my goal?) Considering that Google has been a wall from time to time, forget it. )
3. There are 2 kinds of situations:(1), if you receive a reply, then your network allows the maximum MTU
Continue with the previous post to talk about the MTU causing very slow access issues or direct access. Our server is Aliyun Singapore server, after the successful PPTP connection, access to the wall of most sites outside the basic no pressure, but can not put Baidu, it is strange, have access to the wall of Google, Baidu is also the wall of Singapore?After some Baidu +
About MTUMTU (maximum transmission unit) is the maximum number of information packets transmitted by network devices. For various routers, the best MTU value is usually the default value. Sometimes, changing the MTU value can improve the performance of the device, which is easy to do, but in fact, this will often lead to other problems. It is best to keep MTU unc
How can I use the ping command to obtain the best MTU?What is MTU? MTU is called Maximum Transmission Unit in English. MTU refers to the maximum data packet size (in bytes) that can be passed over a layer of communication protocols ). The maximum transmission unit parameter is usually related to the communication inter
MTUIt is the abbreviation of maximum transmission unit, which is the largest transmission unit.Maximum packet transmitted over the networkIn bytes.
Ethernet imposes a limit on the length of data frames. The maximum value is 1500. This feature is called MTU. Most of different types of networks have an upper limit. If an IP packet is to be transmitted on the IP layer and the data length is greater than the MTU
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
The TCP/IP protocol involves four layers: link layer, network layer, transmission layer, and application layer.The Ethernet data frame is at the link layer.IP packageAt the network layerTCP or UDP packetsAt the transport layerData in TCP or UDP(Data) at the application layerTheirLink isData frame {IP packet {TCP or UDP packet {Data }}}---------------------------------------------------------------------------------The maximum length of Data used in applications depends on the underlying limits.L
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
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
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

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
