Read the entire exam first and check for addressing issues. Do not skip any details or sections. Manage your time. Make a plan to cover all the sections in the time provided. Work out how much time you will spend on each section, keeping in mind the point value of the questions.

Clarify the requirements of each question. During the lab, if you are in any doubt, verify your understanding of the question with the proctor. Do each question as a unit. Configure and verify before moving to the next question. You may want to redraw the topology with all the details available. This will help you visualize and map the network.

You must know how to troubleshoot using the tools available. Work on the things you are more comfortable with and go back to difficult items later. Keep a list. During the exam, make notes on configurations and settings as you move through the exam. Test your work. Never rely on a configuration done in the early hours of the exam. There is a possibility that an item you configured a few sections earlier can become broken and non-functional.

Keep in mind that points are awarded for working configuration only. Save your configurations often. Speed is vital on the exam. Review and practice core material the week before the exam to ensure you can move quickly through the less challenging questions. A physical diagram is not the same as a logical layer 2 diagram. A logical layer 2 diagram will include the VLAN assignments, trunks, EtherChannels, dot1q tunnels, VTP and possibly spanning tree information like root bridges, root ports, designated ports, etc.

The choice to draw out the spanning tree information will really come down to the lab itself. If there are a lot of tasks that relate to spanning tree or layer 2 traffic engineering i. The logical layer 3 diagram will be provided BUT the diagram they provide may not have the level of detail you want or need plus you can not write on the diagram they give you.

Technically you can write on it but they will suspend you from the lab for one year. You should also draw out the diagram for every practice lab you do. Do not wait until the real lab to draw out your first diagram.

As I have said before you never want to do anything in the CCIE lab for the first time other than get your number There are two main benefits to making your own logical layer 3 diagram. Smart people fail the lab all the time because they make stupid mistakes in the lab and by drawing out the network you will hopefully lower the chances of making these stupid mistake i. All it takes is two or three of these little mistakes and you have lost 8 or 9 points in the lab.

We all know that it is hard enough to pass the lab without adding in stupid mistakes into the mix. You will also find tasks related to BGP to be easier to answer when you have a diagram that you can take notes on i.

It is possible that when you get into the lab that basic BGP is done for you. If this is the case you should not be in the lab in the first place. If it is taking you the full 8 hours to just configure the network you more than likely will not pass the lab to begin with so taking the 10 minutes to draw out the network is not going to really matter in this case. The percentage of people who pass the lab while configuring the network for the full 8 hours is slim.

Most people who pass the lab complete the lab within 5. CCIE course: 1. Cisco Frame Relay Solutions Guide 8. Cisco LAN Switching 9. Implementing Cisco Ipv6 Network Ipv6 Internet Routing Architectures, Second Edition Cisco Documentation: Web site: www.

Before deciding to install a new IOS image, be sure that your router has enough Flash memory to support the image.

Images from different feature sets may require more Flash memory than you currently have installed. You will notice that the command requires us to provide information on the image filename and the IP address of the TFTP server. The contents of Flash can also be viewed using the dir command. You will always need to know the name of the images you want to back up or restore. You should also ensure that the TFTP server is available and has enough room to store the image prior to attempting a backup.

Erase flash: before copying? OK 0xB6BD bytes copied in Otherwise, there would not have been enough space to complete the copy process. Finally, use the show version command to ensure that the router is now running the IOS version that you intended to install.

Processor board ID , with hardware revision Bridging software. Depending upon your model and IOS version, you may be prompted to boot into the ROM-based image after issuing the copy tftp flash command, or you may need to change what are known as configuration register settings.

To suit this purpose, IP must define an addressing scheme, so that a packet's intended destination can be indicated. An IP address is composed of 32 bits. These 32 bits are divided into 4 octets of 8 bits each. You may have seen an IP address represented like this: We must remember, however, that the computer understands this number only in binary, so we must often deal with them in binary.

Many people are intimidated by this initially, but soon find that it is not difficult. If you do not allow yourself to be flustered, you can master this topic.

IP addresses are assigned to organizations in blocks. Each block belongs to one of three classes: class A, class B, or class C. You can tell what class an IP address is by the value in its first octet. The first field identifies the network, and the second field identifies the node on the network. Which bits of the address are in the network field and which bits are in the host field is determined by the subnet mask.

When a class A IP license is granted, you are assigned something like this: Only the value of the bits in the first octet is assigned. This means you are free to assign any values you wish in the second, third and fourth octets. The default subnet mask for a class A network is High bits, ones, indicate the bits that are part of the network field of the IP address. The default subnet mask does not create subnets. Therefore, a class A network with the default subnet mask is one network.

The three octets that are unassigned and unmasked are part of the host field of the address.

For some time now I have been asked how I simulate hosts in GNS3 and my stock answer was to configure a router as a host by issuing the "no ip routing" command and setting a default gateway with the "ip default-gateway" command. You would also need to assign an IP address to the interface connected to the router performing routing, or a switch which in turn is connected to a router doing the routing. It worked a treat but had one major flaw, namely, CPU overhead. I know that a lot of people tried putting loopback adapters at either end of a topology but when pinging between multiple loopback adapters the traffic stayed on the PC and would not pass through the routers configured in GNS3.
