• This section is comprised of set of configuration tasks to be completed within 5.30 hours.
• The final score of this secion is combined with the troubleshooting section to comprise your
final pass or fail staus on the ccie lab exam
• A candidate is required to pass both sections of cisco ccie certification.
1. Read all questions in each section before proceeding with any configuration .
2. Before starting the exam confirm that all devices in your rack are in working order. During the exam, if
any device is locked or inaccessible for any reason you must recover it. When you comlete the exam
ensure that all devices are accessible to the grading proctor. A device that is not accessible for grading
cannot be marked and may cause you to lose substantial point.
3. Knowledge of implementation and troubleshooting techniques is part of skills tested in the
configuration section of the lab exam.
4. If you suspect that there may be hardware problem with your equipment contact the lab proctor
immediately
5. Points are awarded for working configuration only. Test the functionality of all of the requirements
before you complete your exam. As you configure one part of the exam you may break a previous
requirement or configuration.
6. No partial points can be granted for any question. All requirements nedde to be full fill in order to
receive the points for the question some requiremnts depend on other questions eith er before or after
the current question.
7. You will be presented with preconfiguration Routers and switches. Do not change the following
configuration on the device.
Hostname
Enable password ‘’cisco’’
Console line configuration
8. In any configuration where additional addressing may be necessary. Use only the major network as
displayed in diagram 1. Ensure that it does not conflict with a network that is already used in your
network.
9. Unicast or multicast static and default routes are not permitted unless permission to use them is
directly stated in a specific question. This restricted includes floating static routes and those routes
that were generated by a routing protocol routes to null 0 that are generated as a result of a dynamic
routing protocol solution are permitted.
10. Save your configuration frequently.

1.1 Switch Administration
Configure the ACME headquarters network (AS 12345) as per the following requirements
• The VTP domain must be set to CCIE
•Use VTP version 2
• SW1 must be the VTP server and SW2 must be the VTP client
• Secure all VTP update with an MD5 digest of the ASCII string CCIErock$
• In order to avoid as much as possible unknown unicast flooding in all VLANs the administrator requires
that any dynamic entries learned by either SW1 to SW2 must be retained for 2 hours before being
refresh,
Configure the network of the new York office (AS 34567) as per the following requirements
• The VTP domain must be set to CCIE
• Use VTP version 2
• SW3 and SW4 must no advertise their VLAN configuration but must forward VTP
advertisement that they receive out their trunk ports
• Secure all VTP update with an MD5 digest of the ASCII string CCIErock?
Solution:
SW1:
VTP domain CCIE
VTP version 2
VTP password CCIErock?
Mac-address again 7200
SW2:
VTP domain CCIE
VTP mode client
VTP password CCIErock?

1.2 layer 2 ports
Configure your network as per the following requirements
• Complete the configuration of all VLANs so that all routers that are located in ACME's headquarters
(AS12345) and new York office (AS34567) can ping their directly connected neighbors
• All four switches (SW1-SW4) must have 4 dot1q trunks that do not rely on any negotiation, do not
configure any etherchannel
• Ensure that the following unused ports on all four switches are shutdown and configured as access
ports in VLAN 999
•E3/0-3 are unused on SWl and SW2
•E1/0-3 are unused on SW3 and SW4
•E3/0-3 are unused on SW3 and SW4
Solution:
SW1/SW4:
interface range E2/0-3
switchport trunk encap dot1q
switchport mode trunk
switchport no negotiation
SW1/SW2
interface range e3/0-3
switchport mode access
switch access VLAN 999
shutdown
SW3/SW4

1.3 Spanning-tree
Configure the ACME network as per the following requirements
• SW1 must be the root switch for all odd VLANs and must be the backup root switch for all even VLANs
• SW2 must be the root switch for all even VLANs and must be the backup root switch for all odd VLANs
• SW3 must be the root switch for all odd VLANs and must be the backup root switch for all even VLANs
• SW4 must be the root switch for all even VLANs and must be the backup root switch for all odd VLANs
• Explicitly configure the root and backup roles ,assuming that other switches with default configuration
may eventually be added in the network in the future
• All switches must maintain one STP instance per VLAN
• Use the STP mode the has only three possible port states
• All access ports must immediately transition to the forwarding state upon linkup and they must still
participate in STP use a single command per switch to enable this feature
• Access ports must automatically shut down if they receive any bpdu and an
administrator must still manually re-enable the port use a single command per switch to enable this
feature
Solution:
SW1-SW4:
spanning-tree mode rapld-pvst+ portfast
spanning-tree default portfast bpduguard default
SW1/SW3:
spanning-tree vlan xxx (even) root primary
spanning-tree vlan xxx (odd) root secondary
SW2/SW4:
spanning-tree vlan xxx (odd) root primary
spanning-tree vlan xxx (even) root secondary

1.4 Wan Switching
• The wan links must rely on a layer 2 protocol that supports link negotiation and authentication
• The service provider expects the both R18 and R19 complete a three-way handshake by providing the
expected response of a challenge that is sent by R63
•R18 must use the username ACME-R18 and password CCIE
•R19 must use the username ACME-R19 and password CCIE
Solution:
R18/R19:
interface s1/0
encap PPP
no peer neighbor-route
ppp chap hostname xxx (R18=ACME-R18,R19=ACME-R19)
ppp chap password CCIE
