Cisco CCNP / BSCI Tutorial: Comparing OSPF and ISIS Hellos

Bsci while studying, and pass an exam to earn certification ccnp to prepare and quick to note that while you Isis RINKUSUTETOPUROTOKORU both of OSPF, there are many differences between the two. One way is the main difference between the two is a protocol to deal with Hello packets. Isis
hello OSPF packet is imperative to maintain relations with the neighboring alive. They are both RINKUSUTETOPUROTOKORU since they both specify the time when the update will be sent. Hello packets are the only method by which routers running OSPF verify that the Isis and the neighbor is not yet available.
ospf us some great options that would maintain the routing table size down to stubs and stubs through the use of the total area, but OSPF, Hello packets are packets Hi. ISHISURUTA that can send two types of hellos - Level 1 and Level 2.
isis routers are classified as Level 1 (L1) and Level 2 (L2), and Level 1-2 (l1 - L2). By default, Cisco routers, L2 router - l1; This is the all-enabled interface AISHISU - l1 and send both L2 hellos.
if interface is one of the adjacent molding L2 only l1, or to submit reasons exist for other types of adjacent hellos. For example, r1 is adjacent to the formation of a ethernet0 interface l1 via r2 is the reason why there is no transmission possible on the router L2 hellos. Hard router interface to send only the L2 hellos or l1, Isis using circuit-type command.
r1 (set) ethernet0
r1 interface (configuration) type circuit level
note Isis 1: This is just to set the interface to send L2 hellos, and a complete command, Isis " type circuit level - 2 -- Only & quot;, rather than simply & quot; " Level 2.
this set out L2 hellos to prevent sent from ethernet0. This is stored in the router because it is unnecessary to use the bandwidth resources, there is no way you can form L2 neighbor - so double-check the command Before using the network topology. earlie jokester

One of the main reasons for the increase in online shopping has been the convenience and security of shopping cart feature on sites of e-commerce. The virtual interface to put things in a cart " " has, at once, a comfortable familiarity and whimsy. It really is an elegant system that has earned the confidence of online shoppers through its proven safety.
There are many different suppliers of services shopping cart. So how does one go about choosing the right path for its E-Commerce Site?
The very first thing you have to do is decide exactly what, and how much product that will be sold. Are you selling 1 item? The line of similar items? A catalogue full of many different products, and if so, how will submit your site in this catalogue?
What is their volume of sales this year? Next year? In five years? Some shopping cart services are great for lower volume of sales with less product variety and no catalogue. Other shopping cart to allow services complex, high volume sales and catalog features.
In terms of cost of the basket of services, you need to find the shopping cart option that matches your sales volume.
PayPal offers a fantastic, free-to-set-up shopping cart that is great for the lower sales volume. Their rates they are a percentage of each of their sales. In addition, you can have large payments automatically by credit card, without the creation of a credit card merchant services. This saves you $ 300 - $ 400 right off the bat.
For high volume of sales you can pay less go with a shopping cart vendor that charges that a monthly fee, rather than a percentage of their sales.
You also need to look at the process of buying trolley service offers. Potential customers abandoning the purchase because they were not shown the costs before they were required to give their credit card information, for example, can be devastating for sales. The simpler, clearer and shorter the process of cart for sale, the better. At no point should the potential ciustomer feel that there is a surprise in front.

And this is highly recommended. The disadvantage of online purchases is that the client must wait for the item to be sent. Having to wait even longer for a money to be received, or worse, a check to clear, on top of navigation time reduces the convenience of online purchases to the extent that sales could be lost. rodney sibyl
