Cisco CCNA / CCNP Home Lab Tutorial: Planning Ahead For IE Study

March 26, 2010 Posted by pass4sure

Candidates preparing for CCNP certification exam is up laboratories for the home of Cisco, as never before. The CCNA and CCNP home lab cheaper than ever, candidates have realized the importance of the work to earn real money on Cisco routers and switches on the course of their qualifications.

One question that often CCNP candidate goes like this: I plan to continue the CCIE after I get my CCNP.

It will sound strange coming from me because I was the No. 1 proponent of CCNA and CCNP candidates buying their own houses laboratories. When it comes to CCIE, but I must say that you are probably better to invest rather than rack rents a lot of money now to buy more expensive equipment with which to earn your CCNP.

Prepare Many of the 2500 and 2600 routers is that you have bought, all for your CCNA exam and CCNP, which can be used to manufacture it is not possible for IE Can. (For example, while the 2500 routers for CCNA and NP study is fantastic, should not be used for the study of IE.) The problem with buying expensive equipment that Cisco CCIE Updates on the right laboratory equipment list twice a year and these moves can be very expensive for those caught in the middle of these changes.

Let me give you an example I myself experience. When I started pursuing CCIE Catalyst switches have been developed in the laboratory. I had a cat I used 5000 for the practice. When I was in the middle of my preparation, Cisco introduced L3 switched to the laboratory in the form of two 3550 switches. Not only that the cat is now almost useless for the study of IU, the new switches went for about $ 5500 each, if I wanted to stay up to date with changes in the new laboratory was cost me $ 11,000.

Again, I know that it is extremely important to teach CCNA and CCNP candidates today with practical experience in home laboratories. It is also much more to think if you earn your CCNP, CCIE and exercise is one of the best decisions ever. Just keep it regularly updated CCIE lab in mind. I encourage you not to keep your budget CCNP, and invest in more expensive routers with IE in mind and wait until you pass the CCNP and CCIE are active members in a trial before a decision between rent Rack

Passing Traceroute:one of the most important Cisco’s CCNA and CCNP Exams

February 24, 2010 Posted by pass4sure

In preparation for your CCNA CCNP exam success, you must learn to deal with routers Cisco. And while Ping is an excellent tool for basic connectivity IP that will give you all the information you need to diagnose network connection.

Type escape sequence to cancel.

The five years shows that there is no link IP CityB. The problem is that almost all ping tells you. You can have 5 or 50 routers between two points, just as one can say that the downstream router is the problem?

Comes traceroute Traceroute sends three datagrams with a Time To Live (TTL) of 1 The datagrams over when they reach the first router on the path to the router and to respond with an ICMP Time Exceeded.

Type escape sequence to cancel.

This indicates that the router at 30.1.1.1 does not know the destination. You now have a better idea of the router has a 350-030 problem!

Now here’s the bad: it will go to 30 lines of three asterisks, and until you leave the traceroute, you can simply go on television with an asterisk on the screen. There are a number of abandonment that the router output above the first line of the console, but do not tell that the router is! So I will – the top secret movie twice, one after another.

The button takes a little getting used to, but one or 642-825 can do it! Add this command to your Cisco skills and will be quite useful for both exams and CCNA CCNP and real-world networks. And impress your friends know how to stop a traceroute!

Analysis of Cisco CCNP Certification / BSCI Exam Tutorial of the basic learning route

January 28, 2010 Posted by pass4sure

To pass your BSCI exam and earn your CCNA certification, you’ve got to master route summarization. When you get to the BSCI level, actually breaking the routes down into binary strings and performing summarization is second nature to you. (If it isn’t, get some more practice!) What makes Cisco / BSCI route summarization more difficult is just keeping the different protocol summarization commands straight!

When you abridge routes in RIP, IGRP, EIGRP, or OSPF, you’re replacing a alternation of routes with a arbitrary avenue and mask. With RIP, IGRP, and EIGRP, this in fact lessens the admeasurement of the acquisition amend packet itself – assorted routes are replaced with the arbitrary route. For instance, the routes 8.0.0.0/8, 9.0.0.0/8, 10.0.0.0/8, and 11.0.0.0/8 can be abbreviated as 8.0.0.0 252.0.0.0. Only the arbitrary abode will be begin in the amend packet, authoritative it abridged yet complete.

As you acquire your CCNA and CCNP certification, you’re traveling to accept to get adequate with manually summarizing routes. This isn’t just addition acumen to apprentice bifold algebraic (although it’s a acceptable one!), but summarizing routes is a accurate real-world accomplishment that can advice your arrangement accomplish added efficiently. So the catechism isn’t just how to abridge routes, it’s why.

To adapt for success on your CCNA and CCNP exam, you’ve got to apperceive how to abridge routes as able-bodied as the specific commands for accomplishing so with OSPF, EIGRP, RIP, and IGRP – but alive why to abridge routes is just as important as alive how! Here are some added tips on avenue summarization.

Summarizing routes can aswell accomplish the acquisition table smaller, yet still acquiesce for complete IP connectivity if done correctly. Using the aloft example, the four more-specific routes will be replaced by a individual arbitrary route. Since the absolute acquisition table is parsed afore the acquisition action is complete, befitting the acquisition table as baby as accessible does advice acceleration the acquisition action as a whole.

With RIP adaptation 2 and EIGRP, chiral avenue summarization is configured on the interface that will be commercial the summary. This is done with the avenue summarization command “ip summary-address.”

OSPF offers two altered avenue summarization commands. To abridge routes from one OSPF breadth to another, use the “area range” command; to abridge routes abstruse via redistribution, use the “summary-address” command on the ASBR.

With able planning and an compassionate of bifold math, you’ll adept avenue summarization bound with some convenance – and you’ll be accessible for success on real-world networks as able-bodied as the CCNA and CCNP exams!

Become a Certified Expert In CCNP Certification,You Need A Procedures Necessary

January 21, 2010 Posted by pass4sure

ne of the important acceptance courses from Cisco is CCNP acceptance and they are actual bargain accepted as Cisco certified arrangement professional. Professionals who are from advice technology accomplishments should charge to accredit this acceptance advance in adjustment to get acceptable job as able-bodied as with a bigger salary.

So,the above accommodation for certifying this acceptance is that you should accept your CCNA certification. This acceptance will advice to accretion assertive accreditation that accord with the networking accompanying appearance and aswell ability about administrating the routers as able-bodied as switches of any arrangement like LAN, WAN etc. In added words, ample calibration industries with the networking accomplishments will be gluttonous for the professionals who accept completed their CCNP acceptance with latest modules.

Exam procedures for CCNP certification:

You can baddest your assay date as able-bodied as affair afterwards the transaction of the fee. It is not compulsatory that you accept to address all exams in the aforementioned anniversary or month. It is absolutely of candidate’s best and even anniversary assay can be accounting already in a anniversary or already in a month. Candidates who accept ability on switches as able-bodied as routers can accept the accumulated assay (3 exams) action for certification.

Certifying the CCNP acceptance is accessible in either means by accessory 3 exams or by 4 exams. All the assay data are accessible in the Cisco website and candidates are requested to accept a glance in the website at approved intervals for the assay date as able-bodied as the assay sessions. Many candidates are accommodating to accept the 4 exams arrangement adjustment as they can get their complete abstraction abstracts for anniversary examinations and acceptable array can be achieved

Candidates accept to bethink one capital abstraction that this acceptance is accurate for just 3 years and afterwards that candidates accept to recertify by autograph BCSI assay and afresh CIT exam. If the authority aeon expires, afresh the acceptance won’t advice you anymore and afresh you charge to re-apply for the acceptance advance from the beginning.

Sticky: *TechNotes* BSCI

October 25, 2009 Posted by pass4sure

The Enhanced Interior Gateway Routing Protocol (EIGRP) is the successor of IGRP, it is more scalable and offers faster convergence. Unlike IGRP, EIGRP is a classless routing protocol, hence it supports VLSM. It is developed by Cisco and is supported on Cisco equipment only. In addition to IP, EIGRP can also be used to route IPX and AppleTalk. In contrary to IGRP, EIGRP is consider to be a hybrid routing protocol, because it has distance vector as well as link-state characteristics. EIGRP is a distance vector protocol with link-state characteristics, routing updates can be partial, they do not need to contain the complete routing table such as with RIP and IGRP. Also, updates are not send periodically, but only when necessary, and only to those neighboring routers that need to know. This results in low bandwidth and CPU usage, and makes EIGRP a fast routing protocol suitable for large networks. The maximum hopcount in EIGRP is 224. EIGRP allows for secure routing updates using authentication, to prevent unauthorized or false routing messages, although this is disabled by default. EIGRP updates use the multicast address 224.0.0.10.

Besides maintaining a routing table, EIGRP maintains a topology table based on the information it receives in hello packets, and a neighbor table listing the directly connected neighbors. The neighbors are discovered using hello packets, which are send out periodically to check if the connection to the neighbor is still available. EIGRP uses five packet types: Hello/Acks, Updates, Queries, Replies, and Requests. When an EIGRP router stops receiving hello packets from a neighbor for a configurable amount of time, it will consider the router as unreachable. The topology database will be searched for backup route known as a feasible successor, if there isn’t one, a multicast will be send out to find a new route. If another router responds with an alternative route, a change will be made to the topology table and a new route will be added to the routing table.

EIGRP uses the Diffusing Update Algorithm (DUAL) for route calculation and to prevent routing loops. The best route is determined based on 2 metrics by default, bandwidth and delay, but others can be used as well

I failed to understand when we use command

metric weight tos K1 K2 K3 K4 K5

what is connection with Ks and bandwidth, delay, reliability, load and MTU? Is K1= bandwith and so forth?
Well when I look at the formula to calculate the composite metics, I am not sure which K variable should be used for MTU and for delay?
Ok, tos is Type of Service and must be 0? Ok, but then why do we need tos in our formula when it is always 0?

I do realise that each constant is used to assign a weight to a specific variable.
