Lab Configuration Guide Copyright © 2007, Cisco Systems, Inc Figure 1-2: Serial Connectivity Diagram for Modules – Discussion The diagrams shown above describe Ethernet and serial connectivity between the routers of your pod These 13 connections, serial and Ethernet, will be used as the master template for most labs in the CCNP4 (Optimizing Converged Cisco Networks (ONT)) curricula The notable exceptions are the labs in Module 6, which will be discussed later All the labs in Modules through assume that you have complete control over each of the devices in your pod, including access to the switch to configure VLANs and assign switchports as access ports on a VLAN or as trunk ports Although most labs not make use of every single link, you should cable your pod according to the both diagrams in order to avoid re-cabling your pod for each scenario Modules 3, 4, 5: Quality of Service Scenarios The Quality of Service (QoS) labs in the ONT curriculum will use all of the Ethernet and serial connections in the topology diagrams shown on pages and of this document, but not every connection will be used in every lab 2-9 CCNP: Optimizing Converged Networks v5.0 - Lab Configuration Guide Copyright © 2007, Cisco Systems, Inc Therefore, cable your pod of four routers and one switch with the connections shown The Cisco Networking Academy Program intends to provide access to Cisco’s Pagent toolset for these labs The Pagent toolset functions on top of the typical Cisco IOS image, but comes bundled with the IOS image You will also need a license key provided by Cisco for each individual router on which you intend to use the Pagent-IOS image Download the Pagent-IOS image and copy it into R4’s flash memory When prompted, use the Machine ID that Pagent generates to retrieve your license key The Quality of Service (QoS) labs in the ONT curriculum suggest that you use Pagent’s TGN traffic generation tool to test the QoS tools implemented in each lab The authors have designed two basic topologies to be used for connectivity to the traffic generator on R4 You will use the Basic Pagent Configuration primarily to test QoS tools in isolation Traffic is generated on R4’s Fast Ethernet 0/0 interface, which is destined for R4’s Fast Ethernet 0/1 interface The purpose being that traffic traverses your topology from end to end so that you can observe bottlenecks The traffic may need to pass over Ethernet VLANs or point-to-point serial links before arriving back at R4 The IOS configurations for R4, with which you should begin each of the labs that use the Basic Pagent Configuration, are provided in ONT Lab 3.1: Preparing for QoS Figure 2-1 illustrates the general description of the Basic Pagent Configuration, while Figure 2-2 illustrates a specific example of how the Basic Pagent Configuration could be applied in a single-router network topology 3-9 CCNP: Optimizing Converged Networks v5.0 - Lab Configuration Guide Copyright © 2007, Cisco Systems, Inc Figure 2-1: Figure 2-2: 4-9 Basic Pagent Configuration A Sample Topology using the Basic Pagent Configuration CCNP: Optimizing Converged Networks v5.0 - Lab Configuration Guide Copyright © 2007, Cisco Systems, Inc Only one switch should be used for these labs When the diagrams show two switches, this is simply for the purpose of showing the logical segmentation of the VLANs Configure the switchports shown in the diagram to access the VLANs shown For instance, if you were configuring the general topology for Figure 2-1, you would use the following configuration: ALS1# configure terminal ALS1(config)# interface fastethernet0/1 ALS1(config-if)# switchport access vlan 10 ALS1(config-if)# switchport mode access ALS1(config-if)# interface fastethernet0/7 ALS1(config-if)# switchport access vlan 10 ALS1(config-if)# switchport mode access ALS1(config-if)# interface fastethernet0/8 ALS1(config-if)# switchport access vlan 20 ALS1(config-if)# switchport mode access If you were configuring the Sample Topology shown in Figure 2-2, you would add the following configuration to ALS1 to connect R1’s FastEthernet 0/1 interface to VLAN 20: ALS1(config)# interface fastethernet0/2 ALS1(config-if)# switchport access vlan 20 ALS1(config-if)# switchport mode access Since each of the labs that use the Basic Pagent Configuration may use R1, R2 or R3 as the exit point of the network topology, you will be told which interface to configure on the switch in the Preparation step of each of the Basic Pagent Configuration labs Key Point Our intent in providing the configuration in Lab 3.1 is that you would use these as a basic starting point in these labs so that you not need to reconfigure basic connectivity and traffic generation in each scenario However, you may indeed need to add additional configuration to the switch in order to achieve the connectivity desired in each lab You will use the Advanced Pagent Configuration primarily to test QoS tools in integration labs These labs are designed to demonstrate traffic traversing from one LAN environment through a WAN connection and back into another LAN environment 5-9 CCNP: Optimizing Converged Networks v5.0 - Lab Configuration Guide Copyright © 2007, Cisco Systems, Inc Figure 2-3: Advanced Pagent Configuration After aggregating the two serial links between R3 and R4, the bandwidth across each link funnels down from 100 Mbps to a maximum of 2.048 Mbps (E1 speed) across the link from R2 to R3 This allows you to see how QoS tools function at each bottleneck as traffic passes in a loop through R1 Ỉ R4 Ỉ R3 Ỉ R2 Finally, in Appendix A of this guide, a diagram of possible quality of service scenarios is given that you can use if you should choose to create your own labs based on the Advanced Pagent Configuration We provide this with the intent that instructors and students experiment with different QoS technologies beyond the implementations in these labs Module 6: Wireless Scenarios The first three wireless scenarios in the CCNP: Optimizing Converged Networks (ONT) curriculum corresponds with the wireless scenarios in the CCNP: Building Multilayer Switched networks (BCMSN) curriculum Labs 6.1 and 6.2 guide students through setting up a basic wireless network using lightweight access points (LWAPs) and a WLAN controller Three extension labs then guide students through connecting to the WLANs and implementing wireless security features Thus, Labs 6.1 and 6.2 should be accomplished in entirety before beginning Labs 6.3, 6.4, and 6.5 Because these labs have been taken from the BCMSN curriculum, they use a set of switches, a WLAN controller (either a network module or an external WLAN controller), and a set of access points You will also need at most two hosts to accomplish these labs since much of the configuration of the WLAN controller is done via HTTP 6-9 CCNP: Optimizing Converged Networks v5.0 -
