CREATING A REMOTE ACCESS POLICY FOR DOMAIN ADMINISTRATORS IN THIS PROC...

3.

If you use static routing on your network, and several administrators are respon­

sible for creating the routing table entries on your routers, what should you do if

you open the Routing And Remote Access console on one of your routers, click

the Static Routes subheading, and see no entries?

Lesson Summary

■J

Tracert.exe is a command line tool that can help you locate a non-functioning

router on the network. TRACERT uses ICMP Echo Request messages with incre­

menting TTL values to test the connection to each router on the path to a given

destination.

■J

Pathping.exe is a command line tool that sends large numbers of test messages to

each router on the path to a particular destination and compiles statistics regarding

dropped packets. Pathping.exe is best suited to locating a router that is malfunc­

tioning, but still operational.

■J

When a routing table lacks the proper entries, the cause depends on whether you

use static or dynamic routing on the network.

■J

For an RRAS router to use either RIP or OSPF, you must install the routing protocol

and then select the interfaces over which the protocol will transmit messages.

■J

Incorrect routing protocol configurations can prevent the routers on the network

from sharing their routing table entries, which in turn prevents the routers from

forwarding traffic properly.

Case Scenario Exercise�

You are the network infrastructure design specialist for Litware Inc., a manufacturer of

specialized scientific software products, and you have already created a network

design for their new office building, as described in the Case Scenario Exercise in

Chapter 1. The office building is a three-story brick structure built in the late 1940s,

which has since been retrofitted with several types of network cabling by various ten-

ants. Your network design for the building calls for the installation of four LANs, each

of which is connected to a fifth, backbone network. The backbone is connected to the

company’s home office using a T-1 leased line, and a second T-1 connects the back-

bone to an ISP’s network, for Internet access.

To connect the building’s internetwork to the company’s home office and to the ISP,

you must install two routers, and you have decided to use computers running

Windows Server 2003 and the Routing and Remote Access service. The first computer

running Windows Server 2003 is called Router01 and two network interface adapters

are installed in it. In the Network Connections tool, the adapter connecting the com­

puter to the local network is called LAN Connection and the adapter connected to the

T-1 providing access to the home office network is called WAN Connection. The sec­

ond computer, Router02, also has two network interface adapters, named LAN Connec­

tion and ISP Connection, respectively.

The Litware home office network and all the company’s other branch offices use RIP,

and you have already configured the routers connecting the building’s LANs to use RIP.
