The Different Types of Areas

The only obligatory area is Area 0, also known as the backbone area or Area 0.0.0.0. In addition to the backbone area, which connects the other areas, OSPF networks use several other types of areas. The following are the different types of areas An ordinary or standard area This area, described earlier, connects to the backbone. The area is seen as an entity unto itself. Every router knows about every network in the area, and each router has the same topological database. However, the routing...

Assigning Ip Vlsm Subnets for WAN Connections

One common approach is to allocate a subnet that has not been assigned to hosts, and to variably subnet it for use with connectivity between rather than within areas. In this case study, it is sensible to take a subnet from the bits allocated to the buildings. Because there are enough bits allocated to address eight buildings, you have twice as many subnets as required. Even with the possibility of growth, one subnet would not be missed. Because the building bits come after the bits assigned to...

Redistribution Example

Refer to Figure 10-12 for this example of route redistribution, without redundant paths, between different routing protocols. Figure 10-12 Simple Redistribution Between RIP and EIGRP Figure 10-12 Simple Redistribution Between RIP and EIGRP I Redistribution of static + RIP RIP one way redistribution no need for distribution lists I Redistribution of static + RIP RIP one way redistribution no need for distribution lists Figure 10-12 shows local offices connecting to the main office via Frame...

Advantages of Summarization

The advantages of summarization are as follows To reduce the size of the routing table To make communication of routing updates more efficient To reduce CPU and memory utilization To maximize the use of IP addresses To isolate topographical changes from other areas Table 3-12 outlines the IP address ranges reserved for private addressing, as specified in RFC 1918.

The show ip ospf interface Command

Show ip ospf interface type-number This command is used to show how OSPF has been configured on an interface level, as well as how it is working at the interface. This level of detail is excellent for troubleshooting configuration errors. Example 5-8 shows the output of this command. Table 5-10 explains how to read this information. Example 5-8 show ip ospf interface type-number Output SanJose show ip ospf interface fastethernet1 0 FastEthernet1 0 is up, line protocol is up Internet Address...

The route-map command is shown here and is followed by the route map configuration commands match and set. route-map map-tag permit deny sequence-number Table 10-13 describes the syntax options available for the route-map command. Table 10-13 The route-map Command Options map-tag This is the name of the route map. This name is used to reference the route map when using the redistribute router configuration command. permit I deny (Optional) If the match criteria are met for this route map and...

Configuring EIGRP for IPX

NOTE This section is included to place EIGRP in context. The exam will test only on topics pertaining to EIGRP using IP. Therefore, this section should be read only for interest and should not be studied in depth in preparation for the Routing exam. The configuration of IPX is very similar to IP. The difference is that IPX is a client server-based protocol that was originally designed to operate in a LAN environment. Although Novell has improved its technology over the past few years to allow...

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,...
