CCNP-BCMSN-v5.0 Lab Case Study 2: Voice and Security in a Switched Network

!!!I used real Cisco 3550 switch *4 to do this lab. I did not use Dynamips to do this lab.!!!

Instructions
Plan, design, and implement the International Travel Agency switched network
as shown in the diagram and described below. Implement the design on the lab
set of switches. Verify that all configurations are operational and functioning
according to the guidelines.

Scenario
The International Travel Agency has two distribution switches, DLS1 and DLS2, and two access layer switches, ALS1 and ALS2. Configure a group of switches as follows:

CCNP-BCMSN-v5.0 Lab Case Study 1: VLANs, VTP and Inter-VLAN Routing

!!!I used real Cisco 3550 switch *4  and a router to do this lab. I did not use Dynamips to do this lab.!!!


Instructions
Plan, design, and implement the International Travel Agency switched network as shown in the diagram and described below. Implement the design on the lab set of switches. Verify that all configurations are operational and functioning
according to the guidelines given.


Scenario
You will need to configure a group of switches for the International Travel Agency. It has two distribution switches, DLS1 and DLS2, and two access layer switches, which are ALS1 and ALS2. You will have to design the addressing
scheme to use here. The address space you can use is the 172.16.0.0/16 range. You may subnet it any way you want, although it is recommended for simplicity purposes to use /24 subnets.

CCNP-BCMSN-v5.0 Lab 8-2: Securing Spanning Tree Protocol

!!!I used real Cisco 3550 switch *4 to do this lab. I did not use Dynamips to do this lab.!!!


Objective:
‧ Secure the Layer 2 spanning tree topology with BPDU guard
‧ Protect the primary and secondary root bridge with root guard
‧ Protect switchports from unidirectional links with UDLD


Scenario:
In this lab, you will secure the network against possible spanning tree disruptions

CCNP-BCMSN-v5.0 Lab 8-1: Securing the Layer 2 Switching Devices

!!!I used real Cisco 3550 switch *4 to do this lab. I did not use Dynamips to do this lab.!!!


Objective:
‧ Secure the Layer 2 network against MAC flood attacks
‧ Prevent DHCP spoofing attacks
‧ Prevent unauthorized access to the network using AAA and dot1x


Scenario:
Other security measures need to be put in place to further secure the network, but you begin with configuring the switches against a few specific types of attacks, including MAC flood attacks, DHCP spoofing attacks, and unauthorized access to the local network.

CCNP-BCMSN-v5.0 Lab 7-1: Configuring Switches for IP Telephony Support

!!!I used real Cisco 3550 switch *4 to do this lab. I did not use Dynamips to do this lab.!!!


Objective:
‧ Configure auto QoS to support IP phones
‧ Configure CoS override for data frames
‧ Configure the distribution layer to trust access layer QoS measures
‧ Manually configure CoS for devices that cannot specify CoS (camera)
‧ Configure HSRP for voice and data VLANS to ensure redundancy
‧ Configure 802.1Q trunks and EtherChannels for Layer 2 redundancy and load balancing


Scenario:
You must configure the access and distribution layer switches to trust the CoS
mapping provided by the IP phone through Cisco Discovery Protocol (CDP).It is not
necessary to have a camera to successfully complete the lab.

CCNP-BCMSN-v5.0 Lab 5-1: Hot Standby Router Protocol

!!!I used real Cisco 3550 switch *4 to do this lab. I did not use Dynamips to do this lab.!!!

Objective:
Configure inter-VLAN routing with HSRP to provide redundant, fault tolerant
routing to the internal network.

Scenario:
HSRP provides a transparent failover mechanism to the end stations on the
network.

CCNP-BCMSN-v5.0 Lab 4-2: Inter-VLAN Routing with an Internal Route Processor and Monitoring CEF Functions

!!!I used real Cisco 3550 switch *4 to do this lab. I did not use Dynamips to do this lab.!!!

Objective:
This lab routes between VLANs using a 3560 switch with an internal route
processor using Cisco Express Forwarding (CEF).

Scenario:
After VTP and trunking have been configured for the switches, Switched
Virtual Interfaces (SVI) are used on the distribution layer switch to
route between these VLANs, giving full connectivity to the internal network.

CCNP-BCMSN-v5.0 Lab 3-5: Configuring Etherchannel

!!!I used real Cisco 3550 switch *4 to do this lab. I did not use Dynamips to do this lab.!!!


Objective:
The purpose of this lab is to configure and observe Etherchannel.

Scenario:
Etherchannel allows up to eight redundant links to be bundled together
into one logical link.

CCNP-BCMSN-v5.0 Lab 3-4: Multiple Spanning Tree

!!!I used real Cisco 3550 switch *4 to do this lab. I did not use Dynamips to do this lab.!!!


Objective:
The purpose of this lab is to observe the behavior of MST (multiple spanning tree).

Scenario:
In this lab, we will group VLANs using MST so that we can have less spanning tree
instances running at once to save switch CPU load.
