Keys Points to Remember When Designing an IP Network

The following list of items should be addressed when preparing the IP addressing plan for your network Identifying how many hosts and subnets will be required in the future requires communication with other departments in terms of the growth of personnel as well as the budget for network growth. Without the standard-issue crystal ball, a wider view must be taken at a high level to answer these questions, with the answers coming from a range of sources, including the senior management and...

Extended ping

To check host reachability and network connectivity, use the ping (IP packet Internet groper function) privileged exec command. The extended ping utility is called by entering the command without any destination. This results in the utility asking a series of questions, allowing you to change the defaults. I do not use trace to determine the path taken, but rather to identify where there is a problem in the network. Where the trace utility fails indicates a good starting point for...

Operation of EIGRP

EIGRP is a revised and improved version of IGRP. Its goal is to solve the scaling limitations that IGRP faces, using the distance vector technology from which it grew. EIGRP increases the potential growth of a network by reducing the convergence time. This is achieved by the following The Diffusing Update Algorithm (DUAL) Multicast addressing for updates Holding information about neighbors as opposed to the entire network These features depend on proprietary technology, which centers on local...

Exams Required for Certification

In 2000, Cisco initiated a major revamping of the career certification exams. Several new exams were unveiled, and the Routing exam was one of those. The Routing 2.0 exam replaced the old ACRC exam this is why the exam is called Routing 2.0 sometimes, even though there was never a Routing 1.0 exam. To certify for CCNP, you must pass multiple exams. This book deals with the Routing 2.0 exam Sylvan Promteric exam 640-503. The qualifying exams, the CCNA and the CCDA, require only a single exam....

Scenario

Given the configuration of EIGRP in Example 7-5, perform the tasks and answer the questions listed. The WAN has light user traffic and is a hub-and-spoke configuration, as shown in Figure 7-13. Example 7-5 Scenario 7-2 Configuration interface Serial 0.1 point-to-point bandwidth 25 interface Serial 0.2 point-to-point bandwidth 25 The 256 kbps access line to the hub has 56 kbps access lines to each of 10 spoke sites. Each link has a Frame Relay CIR of 56 kbps. The access line to each router...

Solutions to Scenario 114 Part APlanning

Keeping the design as simple as possible yet not too simple, so that it is still useful as the network evolves is a good practice. In the suggested answers in Tables 11-3 and 11-4, a numbering scheme is presented. Remember, this is one of many solutions available. The reasoning behind this planning is to allow summarization at the Area Border Routers. The first few bits in the third octet indicate the summarization bits. Note that these bits reflect the area 1 bit or 128 identifies area 1,...
