Free Cisco Lab GNS3 Scenario CCIE Final Assessment

Posted by: admin  :  Category: BGP, CCIE, EIGRP, Labs With Solutions, OSPF




The CCIE lab exam is a requirement to obtain your CCIE certification. The lab is an eight-hour, hands-on exam which requires you to configure and troubleshoot a series of complex networks to given specifications. Knowledge of troubleshooting is an important skill and candidates are expected to diagnose and solve issues as part of the CCIE lab exam. This lab exams cost US$1400 per attempt and the failure rate is high about 80 percent, so practice labs are very important part of the preparation for passing this exam on the first try.

In this lab you will configure eight routers in multiple BGP AS. You will also configure OSPF with multiple areas as well as EIGRP routing protocols.

Lab Rules:

  • All IP addresses will be assigned in the class B 152.1.0.0 network.
  • No static or default routes will be used except where stated.
  • Use Process ID 64 for all OSPF configurations.
  • Do not use point-to-multipoint command for OSPF.
  • Make sure to save your configuration regularly.

 Lab Configuration:

  1. Configure the host name of each router to correspond with the router ID R1 to R8.
  2. Configure the enable password on all routers to be cisco.
  3. Configure all other passwords to be sanfran.
  4. Assign the Ethernet interfaces F0/0 of R5, R6, R7, and R8 to VLAN-300
  5. Configure all routers not to translate incorrect commands entered.
  6. Using the first available subnet of 152.1.1.0 assign IP addresses to the F0/0 Ethernet interface of R5, R6, R7, and R8. Assign the addresses in ascending order starting with R5.
  7. Assign the Ethernet interface F0/0 of R1 and R2 to VLAN-200.
  8. Assign the Ethernet interface of F0/1 of R1 and F0/0 of R2 to VLAN-100.
  9. Using the DLCIs provided in the network drawing configure Frame Relay on R1, R2, and R3. Use a physical interface on R2 and R3 and a logical interface on R1.
  10. Using the first subnet of 152.1.10.0 assign IP addresses to R1, R2, and R3. Use the first octal and assign the addresses in ascending order starting with R1.
  11. Using the first available subnet of 152.1.8.0 assign IP addresses with a subnet to address 48 hosts to the Ethernet interface F0/0 of R1 and R3. Assign the first address to R1 and the last to R3.
  12. Using the first available subnet of 152.1.9.0 assign IP addresses with a subnet to address 128 hosts to Ethernet interfaces F0/1 of R1 and F0/0 of R2. Assign the first address to R1 and the last address to R2.
  13. Using the first available subnet in 152.1.20.0 assign IP address to the serial interfaces between R3 and R7. Use the minimum host address needed and assign the address in ascending order starting with R3.
  14. Using the first available subnet in 152.1.12.0 assign IP address to the serial interfaces between R3 and R4. Use the minimum host address needed and assign the address in ascending order starting with R3.
  15. Using the next available subnet in 152.1.12.0 assign IP address to the serial interfaces between R3 and R5. Use the minimum host address needed and assign the address in ascending order starting with R3.
  16. Using the next available subnet in 152.1.12.0 assign IP address to the serial interfaces between R4 and R5. Use the minimum host address needed and assign the address in ascending order starting with R4.
  17. Using the first available subnet in 152.1.11.0 assign IP address to the serial interfaces between R2 and R6. Use the minimum host address needed and assign the address in ascending order starting with R2.
  18. Using the table below assign the following loopback address to the corresponding routers:
Router Loopback Interface IP Address
R1 Loopback 0 152.1.10.1/32
R2 Loopback 0 152.1.10.2/32
R3 Loopback 0 152.1.10.3/32
R4 Loopback 0 152.1.12.4/32
R4 Loopback 1 152.1.13.1/24
R5 Loopback 0 152.1.12.5/32
R5 Loopback 1 152.1.14.1/29
R6 Loopback 0 152.1.11.6/32
R6 Loopback 1 152.1.11.129/26
R7 Loopback 0 152.1.20.7/32
R7 Loopback 1 152.1.20.17/28

 IGP Protocol: 

  1. Configure the Frame Relay connection between R1, R2, and R3 to be in OSPF Area 0.
  2. Configure VLAN 100 to be in OSPF Area 1
  3. Configure VLAN 200 to be in OSPF Area 2
  4. Configure R1 as the DR for Area 1 and R2 as the DR for Area 2
  5. Configure R1 to prefer the Frame Relay over the Ethernet links. All other connection should prefer the interface with the highest bandwidth.
  6. Configure the Hello interval on R3 for two minutes.
  7. Configure EIGRP on the serial interfaces between R3 and R7. Do not send advertisements out any other interface.
  8. Enable EIGRP on all interfaces on R7, but do not send updates out the interface connecting to VLAN 300.
  9. Verify that R7 can see all networks behind R3.
  10. 10.  R3 should only see network 152.1.20.16/28 via R7.
  11. 11.  Insure the R7 does not advertise any routes back to R3 that were learned from R3 and vice versa.
  12. 12.  Enable IGRP using process 56 on R4 and R5 do not run EIGRP on the interface that are connected to other ASs.
  13. 13.  Insure the loopback interfaces on R1, R2, and R3 are being propagated via OSPF even though OSPF is not running on the loopback interfaces and the routs do not show up as OSPF external routes.

EBGP / IBGP:

  1. Configure R1, R2, and R3 to be in BGP AS100. R1 will peer with R2 and R3 and is the only router in AS100 that has two IBGP neighbors.
  2. Configure R4 and R5 in BGP AS200. R4 will peer with R5 and R3.
  3. Configure R6 in BGP AS300
  4. Configure R7 in BGP AS400
  5. Configure R7 to peer with R5, R6, and R8
  6. Configure R5 to peer with R3, R6, R7, and R8.
  7. Configure R6 to peer with R2, R5, R7, and R8.
  8. Verify that R5, R6, and R7 can see all the following networks from R8 via BGP: 148.1.0.0, 148.2.0.0, 148.3.0.0, 148.4.0.0.
  9. Configure AS400 to advertise local network 152.1.20.0 via BGP
  10. 10.  Configure AS300 to advertise local network 152.1.11.128 via BGP
  11. 11.  Configure AS100 to only accept local routes from AS300. All other routes should be accepted via AS200.
  12. 12.  Configure AS100 to accept a default route from AS300 in case of a link failure between AS200 and AS100. Do not advertise the default route outside of AS100.
  13. 13.  Advertise network 152.1.9.0 via IBGP on R1 and R2. Do not use the redistribute command.
  14. 14.  Configure AS100 to advertise all local networks via BGP. To  prevent AS100 fome being used as a transit network, AS300 should only accept local network from AS100
  15. 15.  Configure AS100 to prefer network 152.1.9.0 be reachable by the outside world via link between AS100 and AS300.
  16. 16.  Configure AS100 not to be used as a transit network for AS200 to reach AS300. Do not change the configuration of any router other than R2.
  17. 17.  Verify AS200 and AS300 do not pass network 152.1.9.0.
  18. 18.  Verify R3 uses R5 to reach network 152.1.14.0
  19. 19.  Verify R3 uses R4 to reach network 152.1.13.0
  20. 20.  Configure R7 to originate and advertise network 148.0.0.0, 148.5.0.0, 148.6.0.0, and 148.7.0.0.
  21. 21.  Configure R7 with four additional loopback interfaces loopback 2, 148.0.0.1/16, loopback 3, 148.5.0.1/16, loopback 4, 148.6.0.1/16, and loopback 5, 148.7.0.1/16.
  22. 22.  Configure R5 to advertise as few prefixes for 148.x.0.0 as possible.
  23. 23.  R3 is running an IGP (EIGRP) protocol on the private link to AS400. Configure it to insure that the IGP route to network 152.1.20.16 is favored over the EBGP route.

This concludes the CCIE final assessment lab. The solution configuration is available to registered users.
