CCNP Study Notes 4-route part-route control◆ Passive-interface-can be used in rip ospf. In rip, there are two network commands in the Process of ospf, which only receive and not send packets. In the process of ospf, there are two network commands: 1, advertise the route of the network address segment. The mask length is determined by the interface configuration, not the network. For example, network 10.0.0.

a full mesh of IBGP peers in each system. Peer R1 and R2 using loopback address, not their directly connected interfaces. Advertise all loopback interfaces to the BGP process, except on R2, where the only loopback advertised should is LOOPBAC K 2. On R2, create a static summary route for the rest of it loopback interfaces nad advertise this static route in BGP. R4 should send a summary route to ITA representing all the R4 loopback interfaces. R4 should prefer the path to ITA networks

CSS design guide, Study Notes 1, css design guide This article is about some notes and Experiences after reading Charles Wyke-Smit's "CSS design guide" over the past few days. I seem to be getting started with web design when I was a freshman, because it is not a computer Major, all of them are self-taught. I remember

A long time ago, a predecessor recommended Angularjs to me. But I didn't study hard at the time, just to read a document. Later awakened ... So determined to understand this series of documents, and free translation (English level is not enough ... Can not be said to be translated, some really do not understand, I hope everyone in the process of the visit pointed out the mistakes therein. After 1 months of intermittent efforts, finally the

LTE beginners, if you also for the LTE self-study and confused;LTE scholars, if you're still worried about the effectiveness of LTE learning,If you want to learn LTE well instead of simply learning about LTE,To make LTE learning more effective than to save money,So, watch the video version of the LTE self-study guide so you can win over LTE.From then on, learn lt

mechanism: a production of chicken legs factory, there is only one line, worker a at the top of this line, he is responsible for the chicken leg plastic packaging, and he can only operate a awuawu at the same time (an event queue, The NODEJS process will only handle one event at a time). Workers A is very efficient, often see the process has been perfect chicken legs will not hesitate to carry out packaging, but whenever he saw some have not completed the process of chicken legs into the assemb

When it comes to data mining, we tend to focus on algorithms during modeling while ignoring other steps. In real world data mining projects, other steps are the key to determining project success or failure. Guide to intelligent data analysis is the book recommended by the knime official website (http://tech.knime.org/guide-to-intelligent-data-analysis), according to the CRISP-DM process describes the proce

This book should be studied eight years ago, this is a wasting time tragedy. I hope you study well and take notes . The first chapter of the DirectShow Development Guide covers the following key points:(1) DirectShow compositionI would like to point out two points: one is the filter manager, that is, the filter Graph Manager, which is a filter container, responsible for creating, destroying all filters, fo

About Typescript:Typescript is a free and open source programming language developed by Microsoft. It is a superset of JavaScript and essentially adds optional static types and class-based object-oriented programming to the language. Typescript extends the syntax of JavaScript, so any existing JavaScript program can work without change in typescript. Typescript is designed for the development of large applications, and it generates JavaScript at compile time to ensure compatibility. TypeScript s

, Table. getn (mytable) Do Print (mytable [Index]) End Table. Sort (mytable) This simple function traverses the entire table and rearrange it from small to large. 6.2. Table. insert (mytable, positon, value) Table. the insert function inserts a new value in Table China. The location parameter is optional. If no value is set, a new value is added to the end of table A. If this value is specified, it is inserted to the specified position. Table. insert (mttable, 25, "hello ") 6.3.

number of cycles is not affected. Second, the variable in the loop structure is a local variable. Once the loop ends, it will be clear. To save their values, you must use global variables or higher-level local variables. Break Control Structure The break statement can be forcibly exited from the loop control structure. The user cannot recycle it, and it must be at the end of the program block (usually the if-then statement ). See the following example: For Index = 1,100 do If Index = 52
