CCIE Routing & Switching Lab Workbook Version 4.0 Lab 4
IEWB-RS Lab 4
Difficulty Rating (10 highest): 6
Lab Overview:
The following scenario is a practice lab exam designed to test your skills at
configuring Cisco networking devices. Specifically, this scenario is designed to
assist you in your preparation for Cisco Systems CCIE Routing and Switching
Lab exam. However, remember that in addition to being designed as a
simulation of the actual CCIE lab exam, this practice lab should be used as a
learning tool. Instead of rushing through the lab in order to complete all the
configuration steps, take the time to research the networking technology in
question and gain a deeper understanding of the principles behind its operation.
Lab Instructions:
Prior to starting, ensure that the initial configuration scripts for this lab have been
applied. For a current copy of these scripts, see the Internetwork Expert
members site at http://members.internetworkexpert.com
Refer to the attached diagrams for interface and protocol assignments. Any
reference to X in an IP address refers to your rack number, while any reference
to Y in an IP address refers to your router number.
Upon completion, all devices should have full IP reachability to all networks in the
routing domain, including any networks generated by the backbone routers
unless explicitly specified.
Lab Do s and Don ts:
" Do not change or add any IP addresses from the initial configuration
unless otherwise specified
" Do not change any interface encapsulations unless otherwise specified
" Do not change the console, AUX, and VTY passwords or access methods
unless otherwise specified
" Do not use any static routes, default routes, default networks, or policy
routing unless otherwise specified
" Save your configurations often
" Use hex to replace with Y for any IPv6 addressing

Grading:
This practice lab consists of various sections totaling 100 points. A score of 80
points is required to achieve a passing score. A section must work 100% with the
requirements given in order to be awarded the points for that section. No partial
credit is awarded. If a section has multiple possible solutions, choose the solution
that best meets the requirements.
Grading for this practice lab is available when configured on Internetwork
Expert s racks, or the racks of Internetwork Expert s preferred vendors. See
Internetwork Expert s homepage at http://www.internetworkexpert.com for more
information.
Point Values:
The point values for each section are as follows:

Troubleshooting:
" There are four issues with the initial configurations.
" Each issue is worth one point.
" These issues will need to the solved prior to completion of this lab.
1. Bridging & Switching
1.1. Trunking
" Configure standards based trunks between the following ports:
o SW1 s interfaces Fa0/13, Fa0/14, and Fa0/15 and SW2 s interfaces
Fa0/13, Fa0/14, and Fa0/15.
o SW1 s interfaces Fa0/19, Fa0/20, and Fa0/21 and SW4 s interfaces
Fa0/13, Fa0/14, and Fa0/15.
o SW2 s interfaces Fa0/16, Fa0/17, and Fa0/18 and SW3 s interfaces
Fa0/16, Fa0/17, and Fa0/18.
o SW3 s interfaces Fa0/19, Fa0/20, and Fa0/21 and SW4 s interfaces
Fa0/19, Fa0/20, and Fa0/21.
" Traffic for VLAN 255 should be untagged when sent across any of these
trunks.
3 Points
1.2. VLAN Assignments
" Configure the VTP domain IE between SW1, SW2, SW3, and SW4.
" VTP updates within this domain should be authenticated using the
password of CISCO.
" Configure VLANs as below:
Rack1SW1#show vlan brief | exclude unsup|^ |^1 |active[ \t]+$
VLAN Name Status Ports
---- ----------------- --------- -------------------------------
43 VLAN_DC active Fa0/24
45 VLAN_DE active Fa0/5
12 VLAN_AB active Fa0/1
Rack1SW2#show vlan brief | exclude unsup|^ |^1|active[ \t]+$
VLAN Name Status Ports
---- ----------------- --------- -------------------------------
12 VLAN_AB active Fa0/24
36 VLAN_CF active Fa0/6
45 VLAN_DE active Fa0/4
258 VLAN_BEH active Fa0/2

43 VLAN_DC active Fa0/24

VLAN Name Status Ports
---- ---------------- --------- -------------------------------
6 VLAN_F active Fa0/6
43 VLAN_DC active Fa0/4
2 Points
1.3. Traffic Control
" Enable pruning within the VTP domain.
" Although SW1 and SW3 do not have VLAN 8 locally assigned ensure that
they receive unknown unicast, broadcast, or multicast traffic for VLAN 8
over their lowest numbered trunk link to SW2.
" Traffic for VLAN 8 should not be received over any of the other trunk links.
2 Points
1.4. Spanning-Tree Protocol
" Configure SW1 as the spanning-tree root for VLAN 258.
" Configure SW3 to become the spanning-tree root for VLAN 258 in the
event SW1 is not longer available.
" All VLAN 258 traffic from SW2 to SW1 should transit SW4.
" In the event that SW2 s path to SW1 through SW3 is down, SW2 should
use the directly connected trunk links to reach SW1 directly.
" Use the fewest number of commands to accomplish this task and do not
alter SW1 s port-priorities.

1.5. Link Failure Detection
" Administrators of your network are concerned about SW1 and SW2 not
being able to detect a link failure on port Fa0/15.
" Configure SW1 and SW2 so that port Fa0/15 is brought down in the case
that either switch can send traffic, but not receive, or vice versa.
" As an additional precaution configure SW1 so that interface Fa0/15 is not
mistakenly elected as a designated port in the above case.
2 Points
1.6. Spanning-Tree Protocol
" Ensure the output of the show spanning-tree vlan 258 command on SW3
matches the highlighted output below:
Rack1SW3#show spanning-tree vlan 258
VLAN0258
Spanning tree enabled protocol ieee
