Printer-Friendly Format

Command

IP Split-Horizon EIGRP
Use

Split Horizon protects against routing loops by not accepting routes on the same interface that a router sends updates out.
This normally has to be turned off in hub and spoke topologies to ensure full reachability.
Syntax

Router(config-router)#network
OR
Router(config-router)#network
Example




In this example we will configure EIGRP 100 on all routers in the in topology.

R1(config)#router eigrp 100
R1(config-router)#no auto
R1(config-router)#network 10.4.4.0 0.0.0.255
R1(config-router)#network 1.0.0.0

Notice that EIGRP also stripes the network statements back to its classful network boundary.

3(config)#router eigrp 100
R3(config-router)#no auto
R3(config-router)#network 3.0.0.0
R3(config-router)#network 10.4.4.0 0.0.0.255

If we configure the network statement with a wildcard, we can control what interfaces are put into EIGRP.

R4(config)#router eigrp 100
R4(config-router)#no auto
R4(config-router)#network 4.0.0.0
R4(config-router)#network 10.4.4.0 0.0.0.255

Checking the EIGRP routing tables we see that R1 and R3 have not received any routes.

R1(config-router)#do show ip route eigrp
4.0.0.0/32 is subnetted, 1 subnets
D 4.4.4.4 [90/2297856] via 10.4.4.4, 00:02:34, Serial1/0
R1(config-router)#

R3(config)#do show ip route eigrp
4.0.0.0/32 is subnetted, 1 subnets
D 4.4.4.4 [90/2297856] via 10.4.4.4, 00:02:54, Serial1/0
R3(config)#

R4(config-router)#do show ip route eigrp
1.0.0.0/32 is subnetted, 3 subnets
D 1.1.1.1 [90/2297856] via 10.4.4.1, 00:00:20, Serial0/0
D 1.3.3.3 [90/2297856] via 10.4.4.1, 00:00:20, Serial0/0
D 1.2.2.2 [90/2297856] via 10.4.4.1, 00:00:20, Serial0/0
3.0.0.0/32 is subnetted, 1 subnets
D 3.3.3.3 [90/2297856] via 10.4.4.3, 00:00:28, Serial0/0
R4(config-router)#


Now we will disable split-horizon on R4's frame-relay interface.
R4(config-router)#int s0/0
R4(config-if)#no ip split-horizon eigrp 100
R4(config-if)#
*Mar 1 00:14:05.915: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 100: Neighbor 10.4.4.1 (Serial0/0) is resync: split horizon changed
*Mar 1 00:14:05.919: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 100: Neighbor 10.4.4.3 (Serial0/0) is resync: split horizon changed
R4(config-if)#

Now we see all the routes on R1 and R3.
R1(config-router)#do show ip route eigrp
3.0.0.0/32 is subnetted, 1 subnets
D 3.3.3.3 [90/2809856] via 10.4.4.4, 00:00:58, Serial1/0

D 4.4.4.4 [90/2297856] via 10.4.4.4, 00:00:07, Serial1/0
R1(config-router)#

R3(config-router)#do show ip route eigrp

Difference Between DSL and ADSL

Difference Between DSL and ADSL

DSL vs ADSL
DSL (Digital Subscriber Line) is the generic term for services that provide internet connections using digital data connections between a modem and a phone line. What’s great about DSL, is that even when the phone line is in use, there is no interruption, and you can still experience a high speed internet connection even when you are making calls. The only issue is, that when you are close to the central office of the company with which you are subscribed, you will have faster internet, but when you are far from their central office, although you are within their scope, you will have a slower internet connection.

There are different types of DSL. There’s SDSL, VDSL, and ADSL. ADSL stands for Asymmetric Digital Subscriber Line. This type of service means that the speed of data sent is known as upstream, and the data received is known as downstream, and the speeds are not always guaranteed to be the same. They have different speeds that change from time to time. The most requested service is the ADSL service. In regards to ADSL, the internet service providers offer options for higher bandwidth, in upstream, downstream or both. The only thing is, they naturally charge higher rates for higher speeds.

ADSL uses a special ADSL modem, and a micro-filter in the subscriber’s telephone line.

This is what allows the ADSL service and telephone service to be used at the same time. The word ‘asymmetric’ in ADSL actually means that the downstream is faster than the upstream. ADSL supports a downstream rate of 1.5 to 9 Mbps, and an upstream rate of 16 to 640 Kbps.

When you use ADSL, your PC will always be connected to the internet, as long as the power is on, and once you ‘turn on’ your computer, your PC will automatically have an internet connection, unless you manually disconnect. Unlike dial-ups, ADSL can serve various computers within a house for multiple members simultaneously.

Summary:

The simple difference between DSL and ADSL is that DSL is the generic term for Digital Subscriber Line services, and ADSL, or Asymmetric Digital Subscriber Line, is just one of its types. There are other types of DSL, such as SDSL and VDSL.

Difference Between PPPoE and PPPoA

Difference Between PPPoE and PPPoA

PPPoE vs PPPoA

Many internet users are often plagued with the decision of what kind of protocol to use with their connection. There are many questions, experimentation, and flip-flopping between PPPoE and PPPoA. Unfortunately, many of the confusions hover above these two protocols.

Both of these protocols give internet service providers (ISP) the capability to rollout broadband use. Using these protocols gives relative security as it obliges the end-user to verify or authenticate to a server before having network access.

PPPoE and PPPoA are mainly used with Digital Subscriber Line (DSL). Both protocols provide flexibility in billing which is very advantageous to providers. Moreover, the use of network resources can be monitored easily and along with this feature, troubleshooting and managing network usage is less problematic.

PPPoE is an abbreviation Point-to-Point Protocol over Ethernet and it is a kind of networking protocol that encapsulates PPP frames inside the Ethernet frames. Basically, PPPoE is configured as a point to point connection between two Ethernet ports.

This protocol is normally used in ISP’s lower packages as PPPoE is often utilized to function in lower bandwidth throughput rate. PPPoE is perhaps the most common protocol used when connecting to the internet.

Point-to-Point Protocol over ATM (PPPoA) is also a network protocol but this time, it is for encapsulating frames inside AAL5 or ATM Adaption Layer 5. ATM means Asynchronous Transfer Mode, a kind of switching using time division multiplexing in an asynchronous manner.

In the enterprise packages, PPPoA is typically the protocol of choice. It will require a Static IP configured straight into the hardware (modem). PPPoA is said to have less overheads compared to PPPoE therefore, the former is slightly faster than the latter. However, for the end-user, the difference in speed is almost negligible.

Modems that support PPPoA use Asynchronous Transfer Mode — which uses very small, fixed-length packets, in contrast to Ethernet, which uses relatively large, variable-length packets — to do whatever it needs to do.

Summary:

1. PPPoE means Point-to-Point Protocol over Ethernet while PPPoA means Point-to-Point Protocol over ATM.

2. PPPoE encapsulates PPP frames inside the Ethernet frames while PPPoA encapsulates frames inside AAAL5.

3. PPPoE is often used in lower packages while PPPoA is often used in enterprise packages.

4. PPPoE is more commonly used than PPPoA.

5. PPPoA has slightly less overhead than PPPoE therefore, it is a bit faster.

How to configure DHCP Relay on Cisco ASA Firewall

The ASA 5500 series firewall can work as DHCP relay agent which means that it receives DHCP requests from clients on one interface and forwards the requests to a DHCP server on another interface. Usually the DHCP server is located in the same layer 3 subnet with its clients. There are situations however where we have only one DHCP server but several layer 3 networks exist (on different security zones on a Cisco ASA) and dynamic IP allocation is required for those networks as well. With the DHCP relay feature, we can connect the DHCP server on one network zone and have the firewall forward all DHCP requests from the other network zones to the DHCP server.

The diagram below illustrates a simple network scenario with three security zones (network interfaces) and a single DHCP server. The three network zones are inside, outside and DMZ. The DHCP clients are connected to the inside network and the DHCP server on the DMZ network. The DHCP requests from the clients on the inside network will be relayed to the server on the DMZ network. The server will assign IP addresses in the range 192.168.1.0/24 to the clients.

Configuration

!First identify the DHCP server and the interface it Is connected to
ciscoasa# conf t
ciscoasa(config)# dhcprelay server 10.1.1.100 DMZ
ciscoasa(config)# dhcprelay timeout 90

!Now enable the DHCP relay on the inside interface
ciscoasa(config)# dhcprelay enable inside

!Assign the ASA inside interface IP as default gateway for the clients
ciscoasa(config)# dhcprelay setroute inside

Usage Guidelines

You can add up to four DHCP relay servers per interface. You must add at least one dhcprelay server command to the ASA Firewall configuration before you can enter the dhcprelay enable command. You cannot configure a DHCP client on an interface that has a DHCP relay server configured.

You cannot enable DHCP relay under the following conditions:
• You cannot enable DHCP relay and the DHCP relay server on the same interface.
• You cannot enable DCHP relay and a DHCP server (dhcpd enable) on the same interface.

How do you become smarter?

* Listen to others patiently and hear and learn from what they are saying. Some people are wise, others just hurt and need to talk, while others may try to persuade you into doing things you shouldn't .... don't! Read, research the Internet on different subjects. If we keep our ears and eyes open to the world and truly listen we learn much.

* Pay attention to subjects.

* The best way to become smarter is simply to exercise your brain! You can improve your brain the same way you improve your muscles when you exercise them. Read as much as you can and talk about what you have read with others. Look up information about anything that seems interesting. The more you learn, the more your brain will be able to learn. Try puzzles and brainteasers to improve your problem-solving abilities. You can also browse the Learning Tips section to learn how to take better notes in class, how to listen better, and how to study for tests. The way to improve your brain is the same as the way to improve your muscles - you work out! The more you use your brain, the better it works. Reading is a good way to exercise your brain, especially if you read books that challenge you to think about different things or to imagine different cultures. Puzzles and brain teasers are also good exercise - practice makes perfect, also - as you work more puzzles, you get better at doing them. There are even video games that give your brain a workout! In general, anything you do to try to make yourself really think will make you smarter.

* I don't think there is any way to increase one's I.Q. as an adult, but doing puzzles, logic problems, and researching and trying to answer questions on this website may be a way of improving one's problem solving abilities.

* You have heard the phrase "Use It or Lose It," and that works for the brain as well. The more you use your mind, the more intelligent you will become. Reading, working puzzles, solving problems, visualizing, and imagining are all ways to improve your intelligence. Intelligent people can come up with new ideas and new ways to do things; it really has nothing to do with school or IQ. Even something as simple as trying a new way to get to your destination can help, because you have to think about how to get from one place to the other, and visualize the route. People who use their brains and constantly try to improve their intelligence are less likely to have mental problems as they get older. Of course, people who work at improving their brains will usually do better at school and on IQ tests, but not always.

Doing your work will not make you smarter - it WILL make you have better grades and be able to understand your subjects better. Homework is practicing what you learn to help you learn better. It does not change your brain.
