If you work at home using the internet or are frequently on the
internet checking out websites, then you will want to look into
service from a high speed internet provider. There are several
ways to connect to the internet in order that you receive this
quicker service. You can look into DSL which is at least 5 times
faster than dial up and runs through the phone line. Cable and
satellite internet access are the other choices. After you
choose which connection you are interested in, then you need to
find the high speed internet provider that offers that
particular service.

DSL is a great option for people who live close to the central
office where the DSL comes from. DSL is distance sensitive,
which means that you need to be within three miles of the office
of your high speed internet provider to receive the best
connection. The best way to find out about DSL is to ask
neighbors if they use it and if the do, ask if they are
satisfied with it. DSL is always on, so you do not have to wait
for it to connect to the internet. With better speed than the
dial up method, this may be the right choice for you.

Cable internet runs through your cable line and has amazing
speed. Downloading is quick and easy and it is always on for
your convenience. The only drawback to cable internet may be the
high cost that these high speed internet providers charge. There
may be package deals with your cable TV service or a reduced
priced if you accept a slower access speed, so ask if there are
any discounts that are available. Cable internet is a wonderful
option for those users who are on the internet several times a
day.

Satellite internet may be the only option for consumers in rural
and out of the way areas. Satellite internet uses satellites in
outer space for internet connection. This is a faster option
than dial up, but may be dependent upon the weather, although
most consumers only have problems during major storms. Ask
neighbors about their internet service and if they use satellite
internet service. This is the best way to find out which high
speed internet provider will work for you.

High speed internet providers fill a vital need for internet
users. The important thing to do is to research the provider
group of your choice until you find a high speed internet
provider that offers what you need for you and your family. Once
you do this, then you sure to find the high speed internet
service that is right for you!

Many of us spend significant time on our computers working and
doing various personal business. We access bank accounts, log-on
to sites, and surf the web to areas of interest. When we do all
these great and convenient things, we also need to ensure we are
taking the steps to protect our privacy and the security of our
personal information. That does not happen automatically. Your
computer doesn’t protect you automatically like you might hope
it would. We each have to be aware of the areas of vulnerability
and take the steps to protect our privacy.

When you connect to the internet and surf the web, there are two
things you need to be aware of that affect your privacy. First,
everywhere you go on the internet and everything you see and do
when on-line can be tracked and recorded through your internet
service provider. You can do something about that. You can
protect the privacy of your internet activity by using an
anonymizer service. There are a number to choose from. Learn
more about how an anonymizer service works, and why you need to
use one by clicking here. Take a look at the
Kaxy web proxy.
When you use an anonymizer service prying eyes will not be able
to track your web surfing through your internet service provider
(ISP). That’s an important step to protecting your privacy.

Secondly, when you surf the web, your computer is storing files
and creating records of where you have been and what you have
looked at. You need to clean those hidden files and records that
are being created and stored on your computer. It takes a
special program to do that. Try Evidence Eliminator.

Your computer – like the networks we use to connect our
computers to the web – needs to be secure to protect against
identity theft, a fast growing problem.

OSPF is a major topic on both the CCNA and CCNP exams, and it’s
also the topic that requires the most attention to detail. Where
dynamic routing protocols such as RIP and IGRP have only one
router type, a look at a Cisco routing table shows several
different OSPF route types. R1#show ip route Codes: C -
connected, S – static, I – IGRP, R – RIP, M – mobile, B – BGP D
- EIGRP, EX – EIGRP external, O – OSPF, IA – OSPF inter area N1
- OSPF NSSA external type 1, N2 – OSPF NSSA external type 2 E1 -
OSPF external type 1, E2 – OSPF external type 2, E – EGP In this
tutorial, we’ll take a look at the difference between two of
these route types, E1 and E2. Route redistribution is the
process of taking routes learned via one routing protocol and
injecting those routes into another routing domain. (Static and
connected routes can also be redistributed.) When a router
running OSPF takes routes learned by another routing protocol
and makes them available to the other OSPF-enabled routers it’s
communicating with, that router becomes an Autonomous System
Border Router (ASBR). Let’s work with an example where R1 is
running both OSPF and RIP. R4 is in the same OSPF domain as R1,
and we want R4 to learn the routes that R1 is learning via RIP.
This means we have to perform route redistribution on the ASBR.
The routes that are being redistributed from RIP into OSPF will
appear as E2 routes on R4: R4#show ip route ospf

O E2 5.1.1.1 [110/20] via 172.34.34.3, 00:33:21, Ethernet0

6.0.0.0/32 is subnetted, 1 subnets

O E2 6.1.1.1 [110/20] via 172.34.34.3, 00:33:21, Ethernet0

172.12.0.0/16 is variably subnetted, 2 subnets, 2 masks

O E2 172.12.21.0/30 [110/20] via 172.34.34.3, 00:33:32, Ethernet0

O E2 7.1.1.1 [110/20] via 172.34.34.3, 00:33:21, Ethernet0

15.0.0.0/24 is subnetted, 1 subnets

O E2 15.1.1.0 [110/20] via 172.34.34.3, 00:33:32, Ethernet0

E2 is the default route type for routes learned via
redistribution. The key with E2 routes is that the cost of these
routes reflects only the cost of the path from the ASBR to the
final destination; the cost of the path from R4 to R1 is not
reflected in this cost. (Remember that OSPF’s metric for a path
is referred to as “cost”.) In this example, we want the cost of
the routes to reflect the entire path, not just the path between
the ASBR and the destination network. To do so, the routes must
be redistributed into OSPF as E1 routes on the ASBR, as shown
here. R1#conf t

Enter configuration commands, one per line. End with CNTL/Z.

R1(config)#router ospf 1

R1(config-router)#redistribute rip subnets metric-type 1

Now on R4, the routes appear as E1 routes and have a larger
metric, since the entire path cost is now reflected in the
routing table. O E1 5.1.1.1 [110/94] via 172.34.34.3, 00:33:21,
Ethernet0

6.0.0.0/32 is subnetted, 1 subnets

O E1 6.1.1.1 [110/100] via 172.34.34.3, 00:33:21, Ethernet0

172.12.0.0/16 is variably subnetted, 2 subnets, 2 masks

O E1 172.12.21.0/30 [110/94] via 172.34.34.3, 00:33:32, Ethernet0

O E1 7.1.1.1 [110/94] via 172.34.34.3, 00:33:21, Ethernet0

15.0.0.0/24 is subnetted, 1 subnets

O E1 15.1.1.0 [110/94] via 172.34.34.3, 00:33:32, Ethernet0

Knowing the difference between E1 and E2 routes is vital for
CCNP exam success, as well as fully understanding a production
router’s routing table. Good luck in your studies!
