Labs:

Chapter 1: Selecting, Assembling, and Cabling WAN Components
There are no labs for Chapter 1.
Chapter 2: Configuring Asynchronous Connections with Modems
2.3.2 You are working for the Atlanta Bread Company and would like to setup out-of-band management on your router. You will properly configure an asynchronous connection on your router and dialin from a remote location.
2.3.3 Your colleagues also working for the Atlanta Bread Company would like to dialin to your router. You will properly configure an asynchronous connection on your router using the AUX port and dialin from a remote location.
2.3.4 The Atlanta Bread Company now has a remote office in Macon. You will configure the remote router to establish an asynchronous connection to your router.
Chapter 3: Configuring Point-to-Point Protocol and Controlling Network Access
3.1.4 The CTO of the Atlanta Bread Company has just called you. She is asking why can't she start an EXEC session on the core router through a dialup connection. She would also like to dialin for free internet access. You will configure the core router to permit PPP and EXEC sessions.
3.1.6 The Atlanta Bread Company has a customer that would like to utilize the dialin core router to receive E-mail. The host will specify its own address. You will configure the core router to permit the UNIX host to specify the IP address.
3.2.3 The Atlanta Bread Company is reviewing security policies and it has been noted that there is no authentication on the core router. You will configure PAP authentication between the Atlanta core router and the Macon remote office.
3.3.3 The Atlanta Bread Company is reviewing the costs incurred by the Macon office for dialin access to the core router. A lower telephone rate has been established for your Atlanta office to call to the Macon office. You will configure callback services between the Atlanta core router and the Macon remote office.
3.4.2 The Atlanta Bread Company is again reviewing the costs incurred by the Macon office for dialin access to the core router. The CTO has recommended that Stacker compression be added to the asynchronous link between Atlanta and Macon to maintain compatibility with the Cisco 700 series. You will configure compression between the Atlanta core router and the Macon remote office.
Chapter 4: Accessing the Central Site with Windows 9X
4.2.1 The CTO of the Atlanta Bread Company would like for you to setup her laptop for PPP dialin access to the core router. She must have a dedicated line for her private dialin! You will configure a PPP dialup link between the Atlanta core router and this telecommuter.
Chapter 5: Using ISDN and DDR Technologies to Enhance Remote Connectivity
5.5.4 You have just installed a new branch office that will use DDR to dial into your central site.  The next step is to configure routing so the branch office can successfully communicate with the central site using TCP/IP.  You will need to install a default route at the branch office pointing back at the central site.  At the central site you will need to add a static route for the branch office Ethernet network pointing back at the branch office router.  To ensure that the branch office can communicate with the rest of the central site, redistribute the static route to the core network running IGRP.
5.5.5 Given a Central site Cisco-IOS router with ISDN BRI capability and a branch office site Cisco-IOS router with ISDN BRI capability, configure both routers so that you can place an ISDN call between your two company sites.
5.5.6 The Denver office needs to control what interesting traffic will bring up the ISDN connection to the Phoenix office.  You will setup an extended ACL and apply it to the dialer group.
5.5.10 The Phoenix and Denver offices want to exchange routing updates without incurring large telecommunication bills. Your solution is to configure snapshot routing between the two routers.
5.6.1 Configure the branch office router and central site router to dial two B channels for a total link speed of 128kbps.  Use two dialer maps to dial the two phone numbers and enable PPP multilink.
5.6.5

You have other ISDN devices connected to the same ISDN line that your central router is connected to (this is possible with an S/T Interface).  To ensure that they don’t step on each other, we want to configure the central router to only answer calls that are placed to the 5554000 number.

5.8.1 Given a Central site Cisco-IOS router with ISDN PRI capability and branch office site Cisco-IOS routers with ISDN BRI capability, configure all routers so that you can place an ISDN call between your three company sites.
Chapter 6: Optimizing the Use of DDR Interface-Dialer Profiles and Rotary Groups
6.2.6 To simplify the configuration of ISDN DDR implementations, Cisco has created a way for us to separate the configuration of connection specific information from the BRI interface itself.  In this lab you will assign the BRI interface to a rotary group and then create dialer profiles for your connections that will use the BRI interfaces in these rotary groups.
6.3.3

The Denver office needs to control what interesting traffic will bring up the ISDN connection during only open hours.  Last month they received a bill for $729.00 for ISDN service. You will setup a time-range extended ACL and apply it to the dialer group and the BRI interface so that the link will only be operational during business hours.

Chapter 7: Using X.25 for Remote Access
7.2.3 You are working for the Atlanta Bread Company and would like to setup out- of-band management on your router. You will properly configure an asynchronous connection on your router and dialin from a remote location.
7.2.4 Your colleagues also working for the Atlanta Bread Company would like to dialin to your router. You will properly configure an asynchronous connection on your router using the AUX port and dialin from a remote location.
Chapter 8: Frame Relay Connection and Traffic Flow Control
8.2.1 You have been contracted by a small bank to install a Frame Relay network to connect their offices in Atlanta, Orlando, and Houston. Atlanta needs connectivity to both Orlando and Houston. Orlando and Houston do not need connectivity between each other. You have ordered Frame Relay service from a national Frame Relay service provider and have received the DLCIs in the above diagram. Routing should be handled using IGRP.
8.3.4 You have been contracted by a small bank to install a Frame Relay network to connect their offices in Atlanta, Orlando, and Houston. Each office needs to connect to the other two. You have ordered Frame Relay service from a national Frame Relay service provider and have received the DLCIs in the above diagram. Routing should be handled using IGRP.
8.4.7 Your main office in Atlanta has a high-speed T1 Frame Relay connection. It is over-running your remote sites that only have 56K Frame Relay connections. Install rate enforcement on your router in Atlanta to control how much traffic is sent to these sites. Routing should be handled using IGRP.
8.4.8 Your main office in Atlanta has a high-speed T1 Frame Relay connection. There is a bottleneck that exists at the other end of the PVC that connects to Orlando. This is due to the fact that Orlando only has a 56K Frame Relay connection.
8.4.9 Configure rate enforcement on your Frame Relay network that will use a custom queue list to prioritize traffic before it gets throttled based on protocol and port.
8.5.2 You have been contracted by a small bank to install a Frame Relay network to connect their offices in Atlanta and Houston. The frame relay cloud may grow at a later date and to avoid the headache of numerous static routes on the Atlanta hub router, you decide to configure ODR. You have ordered Frame Relay service from a national Frame Relay service provider and have received the DLCIs in the above diagram. Routing should be handled using IGRP. Lastly, the ODR information needs to be redistributed into IGRP.
Chapter 9: Enabling Backup to a Permanent Connection
9.1.1 You have just installed an ISDN line to be used as a dial backup line to your Frame Relay connection between the Atlanta (hub) and Orlando (stub) office.  Configure DDR on the BRI interface of the Orlando router.  Configure Frame Relay on the serial interfaces connecting to the Frame Relay network.  Use floating static routes to control which link is used.
9.1.4.1

You have just installed an ISDN line to be used as standby reserve bandwidth your Frame Relay connection between the Atlanta and Orlando office.  Configure DDR on the BRI interface of the Orlando router.  Configure Frame Relay on the serial interfaces connecting to the Frame Relay network.  Configure parallel static routes so that when both links are up traffic will load balance between the two links.

9.1.4.2 You have just installed an ISDN line to be used as standby reserve bandwidth for your Frame Relay connection between the Atlanta and Orlando office.  Configure DDR using a dialer interface on the Orlando router.  Configure Frame Relay on the serial interfaces connecting to the Frame Relay network.  Configure this to work successfully with IGRP.  EIGRP could also be used.
9.2.3 You have been asked to implement a DDR dial backup link to backup the Frame Relay network between Orlando and Atlanta.  You have installed an ISDN line in Orlando to make this possible.  Now that Orlando has ISDN, you have come up with the idea to take advantage of that line so that you can connect to the Minneapolis office which also has an ISDN line.  Configure a DDR connection between Orlando and Minneapolis.  Because Orlando will be using the same line to connect to two different locations, you must use dialer profiles to make this possible.
Chapter 10: Managing Network Performance with Queuing and Compression
10.2.3 Our company has given us the task of connecting our east coast office with the west coast office via ISDN. There will be some large file transfers over this link but we do not want them to dominate the link. Since we want low bandwidth applications such as telnet to be able to get through at any time, we have decide to use weighted fair queuing to solve this problem. It is our responsibility to connect these two routers together and configure weighted fair queuing correctly.
10.2.5 Our company has given us the task of connecting our east coast office with the west coast office via ISDN. It has been determined that we need to have a strict queuing policy for traffic going across this link. Certain traffic should have a higher priority than other traffic. We have decided that all TCP traffic should have high priority, ICMP traffic should have medium priority, all UDP traffic should have low priority, and all other traffic should have normal priority. It is our responsibility to connect these two routers together and configure priority queuing correctly.
10.2.8 Our company has given us the task of connecting our Houston office with the Orlando office via Frame Relay. 
10.3.7.1 Our company has analyzed the bandwidth usage on our EastCoast to WestCoast ISDN connection. It has been found that we are using the ISDN line to the maximum. There is not enough money in the budget to upgrade the line to a PRI link, or to allow the ISDN line to be on all the time. It is our responsibility to find a way to move more information across the link in less time. Our solution: Compression.
10.3.7.2 Our company has analyzed the bandwidth usage on our Houston to Orlando Frame Relay connection. It has been found that we are using the Frame Relay line to the maximum. There is not enough money in the budget to upgrade the line. It is our responsibility to find a way to move more information across the link. Our solution: Compression.
Chapter 11: Scaling IP Addresses with Network Address Translation
11.3.1 Our small company has recently been assigned the network number 206.222.222.0 by ARIN. Previously the company was using a private IP address on the internal network. Now that the company is going to be connected to the Internet, we need to either go to each and every workstation and configure it with a new IP address, or to use some kind of IP address translation at the router. For security reasons our company does not want the computers to be directly on the Internet, using real IP addresses. Since our company only has a limited number of computers, we have decided to use static network address translation. It is our job to configure the ISDN connection and implement the address translation.
11.3.2 Our small company has recently been assigned the network number 206.222.222.0 by ARIN. Previously the company was using a private IP address on the internal network. Now that the company is going to be connected to the Internet, we need to either go to each and every workstation and configure it with a new IP address, or to use some kind of IP address translation at the router. For security reasons our company does not want the computers to be directly on the Internet, using real IP addresses. Since our company has a large number of computers it would be too time consuming to enter all of the static address translations into the router. Our alternative is dynamic network address translation. It is our job to configure the ISDN connection and implement the address translation.
11.3.3 Our quickly growing company has the network number 206.222.222.0, which was assigned by ARIN. Previously the company was using dynamic address translation over an ISDN line however the company has just upgraded the line to Frame Relay. The company has been growing and has outgrown the number of valid IP addresses. The company is not able to get another class C network from ARIN, so we need to find another solution which will allow all of our employees Internet access without over running the available valid IP addresses. We have researched NAT and found that if set up properly we can translate many internal IP addresses into one valid IP address. This is called Overloading Network Address Translation. It is our job to configure the Frame Relay connection and implement the proper address translation. 
11.3.4 Configure a Frame Relay connection between our WebHeads router in Orlando and the ISP's router in Houston, and configure TCP Load Distribution on the WebHeads router.
11.3.5 Configure an ISDN connection between Bread company router and the Butter company router, and configure it so that the two networks which have the same IP addresses can communicate together. To accomplish the communication we will configure dynamic overlapping network address translation.
Chapter 12: Using AAA to Scale Access Control in an Expanding Network
12.2.2 The Denver office needs to control who logs in to their router and dials in for remote access. In this lab, you will setup AAA Authentication on this router and test each user account.
12.2.3 The Denver office needs to authorize a backup user to issue a few privilege level commands. In this lab, you will setup AAA Authorization on this router and test each user account.
12.2.4 The Denver office needs a record of what commands are being issued on the router and what users are using the PPP modem dial-in. In this lab, you will setup AAA Accouting on this router and test each user account. 
12.2.5 The Denver office has setup and configured a Cisco Secure TACACS+ server and needs to place the routers under the control of the TACACS+ server. In this lab, you may need to modify the hostname and IP address of your router.
