yes, the vro。 forwards the route according to the corresponding static route forwarding group. Otherwise, the vro searches for the dynamic route. Dynamic Routing Protocols are divided into internal gateway protocol (IGP) and external Gateway Protocol (EGP) based on whether they are used in an autonomous domain ). The Autonomous Region refers to a network with a unified management organization and a unified routing policy. The routing protocol used in the autonomous region is called the internal

actually don't need to remember anything. You just need to learn how to use half of the available range to build a ruler. Chart G Remember, all subnets start from an even number and all subnet endpoints are odd. note that 0.0.0.0 to 0.255.255.255 (0.0.0.0/8) is not used, and 127.0.0.0 to 127.255.255.255 (127.0.0.0/8) is used for loop address. 127.0.0.0/8 is interpreted as: the network ID is 127.0.0.0, The subnet mask is eight 1 on the left, and a bunch of 0 subnets on the right The values

. Only Ethernet frames are returned. You can also add the socket created in the old method to the hybrid mode: Int sockfd = socket (pf_packet, sock_raw, htons (eth_p_ip )); Struct ifreq IFR; Bzero ( IFR, sizeof (IFR )); Strcpy (IFR. ifr_name, "eth0 "); If (IOCTL (sockfd, siocgifflags, IFR) Perror ("IOCTL siocgifflags :"); } IFR. ifr_flags | = iff_promisc; If (IOCTL (sockfd, siocsifflags, IFR) Perror ("ioclt siocsifflags :"); } Eth_protocolThe parameter value is as follows. this parameter

each other. Under the guidance of this mode, reinstallation of Windows System disks is very low-cost, as long as the documents are not lost, the application is not lost. How much is wastedGeek has a wonderful time to reinstall the system, and has contributed to a wonderful marriage :). In short, in the GUI era, an application should be installed to solve a problem. As for the communication between applications and the control of applications by using non-keyboard and mouse methods, it is no lon

cannotThe pointer is used as a parameter because the Remote Process and the caller are running in a completely different address space.Once again, because a remote call cannot share the caller's environment, it cannot directly access the caller's I/O descriptor or operating system functions.

that I often have close contact with some of the industry's backbone big names from time to time. Sometimes, when they visit China, they can talk about translation to deal with the media. Sometimes it is a small range of long-time research issues. In the past few years, Jim Gray (1998), Tony Hoare (1980), Butler Lampson (1992 ), nikalus Wirth (1984) also has Chuck Thacker (and Butler Lampson and the other two) that obtained Draper Prize (2004 ). Without the contributions of these people, you an

1. The Cisco switch filters out MAC addresses that are deemed to be obviously invalid. For example, if your device's MAC address is 57-14-00-xx-xx-xx, you cannot communicate with each other. It is unclear how to filter out and which are filtered out. The "Cisco Network Chinese assistant 5.2" tool does not see how to cancel the filter function. Therefore, do not overwrite the MAC address. Usage of the first three digits of the MAC address code: 00000C Cisco00000E Fujitsu00000F NeXT000010 Syt

reporting and handling error situations. The ICMP protocol has multiple functions. In addition to sending route error messages to data senders, it can also detect the accessibility of network nodes (using icmpecho and reply information ), improve routing efficiency (icmpredirect information is used), and remind the sender that the packet exceeds the survival time (icmptimeexceeded information is used. In short, the ICMP protocol is an essential part of the entire IP network, especially for thos

Write in front, before doing a period of time mobile development, and later because of the work reasons stranded, the latest to pick up the Android authoritative Programming Guide to learn, by doing a study note. First of all, I would like to say that whether it is computer trained or training course origin, have heard the high cohesion low coupling and MVC two words. The MVC pattern is to solve the relationship between cohesion and coupling in the process of software engineering. (wiki view t

separate screen? Can pictures be "dragged" from one computer to another? The details of these interactions are also different because of their respective "rules". Some of the difficulties that hand developers face today have reminded me of some of the similar problems that GUI developers have encountered in the early moments. When developing the GUI for the early Xerox PARC, when the user drags the file icon onto the folder icon, it is natural that
