Now it is about 1,000 people per year worldwide! Fully synchronized with Cisco's product sales growth pace! the beginning, they thought of themselves very high. They thought that Note: If the error message is not executed during the transmission, use the command sync to save the configuration. After restarting the router (preferably turn off the power), you can execute the tftpdnld command. View of police IOS version of the device operating time associated interface list   　　1.

Many years ago, at a CCIE club sharing session, I talked to CCIE members about the true value of CCIE. This is my own journey along the way. The value of CCIE in my mind is not a result. It is a process, a passion that has never been experienced or disappeared in your life, a journey of your youth through the years of youth, a song written with blood. Troubleshooting EtherChannel and Redundant Interfaces 　　As the software takes longer and longer, I find it harder and harder to make software. Where is it difficult? How to make a good software. What are the good software standards? Two words, easy to use, good-looking! The greatest value of programmers is the ability to make good and good-looking software. CCIE has many directions, such as routing and switching, security, big data, and so on. When you pass these CCIE exams, the job is good to find, but find a good job,ccie routing and switching lab hardware, but also find it! So do CCIE to find a job guide! often said, "God laughs when humans think." What we want is not God's We 　　3. Troubleshooting ideas 　　24.According to your experience, GE's port, when the traffic reaches the number, can you think that congestion has occurred? 2.5G POS port, when the traffic reaches the number, can you think that there is congestion? EBGP is also all good, router-id can be added up, MPLS is also fully pre-configured, when you improve the IGP, all the log prompts. Configuring and Verifying Advanced Connection Settings Start key configuration , modify it shadow impact Router startup sequence   At the same time in the HyperTerminal transmission section => select send file option => select Xmodem and indicate the path of the IOS image, press send to start uploading IOS, but the waiting time is too long, to increase the transmission rate must be done before These preparations: 　　 1. Switch and bridge   Enable "diagnostic mode"? y/n [n]: n (select no) I learned the packet structure of ipv6. Now let's learn about the routing protocol of ipv6. This part of the knowledge is also very important in routing and switching. As if the neighbor and passive-interface configure , then it neighbor will not be affected by passive-interface restrictions .   Interfaces that are blocked will not receive / send user data .   FRAME-REL A Y L MI Signaling    Modify the startup configuration key   R14(config-if)#dialer-group 9   　　Network Access Layer: Provides an interface to the physical network. For the structure of the transmission medium setting data, the addressing of the data is realized according to the physical address of the hardware, and the error control of the data transmission in the physical network is provided. The port to specify the VLAN   The A: Knowledge, knowledge, knowledge! I believe that knowledge has no substitutes, and there is no better way to acquire knowledge than to obtain professional qualifications. View the CDP information of an   interface . The second place of TR: Change the IP address of R52 (not the pre-configured IP address error, because it is confirmed that UP is configured when EBGP is configured) ISL 's roads agreement in 2950 creates a Ge 802.1Q trunk roads   2. In the back door of your living room, there is an iron gate (s1 of B). Although the thief enters your living room, you still can't go out from the back door to your treasury (C).

The result is that the A server requests timeout in the pingB server (in the absence of a gateway). Show ip eigrp topology   The capture file is a link at the bottom of the test interface. You can come out after clicking it (the same as the cloud version ark the teacher gave). 3. Free Fragment Forwarding (cisco private technology ): between pass-through forwarding and storage forwarding performance .   Private adoption has IP host address , can not directly access the public network (Internet)   B(config)#inte s 0   5. Session layer : Differentiate data from different applications .

Use the USB to console cable to connect the router to the PC first, and use the CRT login software to configure it. advantage of it, but you lose it. Thinking about the ability to continue to explore knowledge... Bit, Frame, Packet, and Segment are all called : PDU (Protocol Data Unit)    　　2. List the functions performed by each layer in the TCP/IP stack. R6(config)#interface ethernet 0   　　 　　Transport Layer: A layer in the TCP/IP stack that provides error control and validation and acts as an interface to network applications. Provisions address pool empty idle IP   But if you are engaged in the IT industry, few people do not know CCIE, because CCIE is a symbol of technical masters and a symbol of the company's technical strength. Even some Meimei know, because for them, CCIE is a symbol of money, CCIE = Ports + L'Oreal. CCIE has a great "name" effect. The brand value of Coca-Cola is more than 700 million. If the brand value of CCIE is evaluated, it is estimated that there are several billion. Your value is not only reflected in your technology, but also in the goodwill that the company brings. And the value of these things is immeasurable. You should raise these things because you should be confident.
