Free Cisco Lab GNS3 Scenario CCNP Final Assessment

Posted by: admin  :  Category: BGP, CCNP, EIGRP, IGRP, OSPF




This lab scenario will test your knowledge of all aspects of the CCNP Routing certification. And will require a broad perspective and knowledge base.I have also included a GNS3 basic configuration which you can download.

You may also download the free solution for this lab but you must fires register there is no charge.

This lab scenario was designed originally using 2500 series Cisco routers and a 2924 Cisco Catalyst switch, so you will need to substitute the proper labels for the serial and Ethernet interfaces for the Cisco router series you are using.

Lab Configuration:

Switch Configuration:

  • Configure the host name as CatSwitch.
  • Set enable password as Cisco.
  • Configure the management address as 192.168.20.1/24 with the Gateway assigned to your terminal or terminal server.
  • Create the VLAN’s as indicated in the network drawing.
  • Assign Ethernet ports to VLAN’s as indicated in the network diagram.

Router Configuration:

  • Configure the host name on all routers as indicated in the network drawing.
  • Configure the enable secret password as Cisco on all routers.
  • Configure all other passwords as Sanfran on all routers.
  • Configure all routers with no DNS resolution.
  • Configure all routers so that the console session will not time out.
  • Configure all routers to display a banner indicating which router you are logging into.
  • Configure Loopback interfaces on all routers as indicated in the network drawing.
  • Create a host table on all routers using the address assigned to Loopback 0 of all other routers in the network.

IP Addressing:

  • Configure the IP address and subnet on the Ethernet interfaces of all routers as shown in the network drawing.
  • Configure the IP address and subnet on the Serial interfaces of indicated router as shown in network drawing.

 

Additional Loopback Interfaces:

  • Create seven loopback interfaces in R1 using the network range 133.33.16.0/24 to 133.33.23.0/24.
  • Create seven loopback interface in R2 using the network range 133.33.24.0/24 to 133.33.31.0/24.
  • Perform network summarization on these interfaces to reduce ip routing table size.
  • Configure a static route to ensure that all loopbacks ranging from 133.16.0 to 133.33.31 are encompassed by a single static routing entry.

IGP Routing:

In the section you will configure IGRP, EIGRP, and OSPF routing protocols across six of the nine routers.

IGRP:

Configure IGRP (AS 1) on R4 and R5 to meet the following:     

  •  
    • Configure IGRP on R5 E0 and E1 interfaces.
    • Configure IGRP on the serial interface between R4 and R5.
    • Ensure proper filtering is configured on R4 to send only networks that do not reside on R5.

EIGRP:

Configure EIGRP on R1, R4 and R6 to meet the following:    

  •  
    • Configure the serial interface between R4 and R6 in EIGRP domain 1.
    •  Configure the VLAN 600 to reside in domain 1.

OSPF:

Configure OSPF on R1, R2, R3, and R4 to meet the following:   

  •  
    • Configure the serial interfaces between R1 and R2, R2 and R3, R1 and R3 to be in OSPF area 0.0.0.0.
    • Configure the serial interfaces between R3 and R4 to be in OSPF area 350.
    • Congure VLAN 100 to be in OSPF area 100.
    • Configure VLAN 200 to be in OSPF area 200.
    • Configure VLAN 300 to be in OSPF area 300.
    • Configure VLAN 400 to be in OSPF area 400. Assign any loopback interfaces into already existing areas

IGP Redistribution:

  •  
    • In the section you will redistribute IGRP, EIGRP, and OSPF routing protocols across six of the nine routers and verify IP connectivity to all routing domains.
    • Redistribute the IGRP route into OSPF
    • Redistribute IGRP into EIGRP
    • Ensure you can see distributed IGRP routes throughout the other protocols.
    • Using the IOS passive-interface command, ensure that only the correct interfaces residing in the IGRP AS are configured to send and receive IGRP updates.
    • Redistribute between EIGRP AS 1 and 2 and verify network connectivity.
    • Verify IGRP and OSPF have these networks present in their IP routing Tables.
    • Ensure the VLAN 600 and loopback interfaces on R6 OSPF cost metric are set to 1000.
    • Configure R6 to set all external EIGRP routes in AS 1 with an administrative distance of 90.
    • Redistribute OSPF into IGRP and EIGRP to maintain full network connectivity.

 

OSPF Modifications:

Configure OSPF to perform the following functions: 

  •  
    • Ensure that R3 is always the DR on the VLAN 300.
    • Change the hello interval between R1 and R3 serial link to 25 seconds.
    • Configure MD% authentication between the serial link of R1 and R3 set the password as cisco
    • Configure the local names of routers R1 to R6 so that all OSPF enabled routers can perform OSPF name lookup.
    • Ensure the router ID on all OSPF enabled routers match the loopbacks.
    • Configure area 200 as a stub area.
    • Ensure the OSPF cost as seen by R1 and R3 for VLAN 200 is 1000.

BGP configuration:

In this section of the exercise we will configure IBGP across your IGP network and minimize the number of IBGP peer sessions. R1 will be the focal point for all IBGP peering sessions and has two EBGP connections to the same ISP provided for redundancy. You will also configure BGP attributes to influence routing decisions made by the IBGP network and influence the path the ISP routers ISP1 and ISP2 choose.

IBGP:

Configure IBGP AS 1 within the network to meet the following conditions:  

  •  
    • Use route reflectors and configure R1 as the route reflector to the route reflector clients R2, R3, R4, R5, and R6.
    • Use BGP peer group on R1.
    • Disable BGP synchronization on all IBGP routers.
    • All IBGP routers should receive routing updates from R1.
    • All IBGP connections must be active as long as the is active path between the routers.

 EBGP:

Router R1 has two EBGP connections to the same ISP multi homed.  

  •  
    • Configure EBGP between R1 AS-1 and ISP1 and ISP2 AS-1024.
    • The routers ISP1 and ISP2 are both connected to AS-1024.
    • Configure ISP1 and ISP2 to provide a default route to R1
    • Configure the following static routes to Null0 on ISP1 and ISP2.
      • ip route 0.0.0.0 0.0.0.0 Null0
      • ip route 1.0.0.0 255.0.0.0 Null0
      • ip route 2.0.0.0 255.0.0.0 Null0
      • ip route 3.0.0.0 255.0.0.0 Null0
      • ip route 4.0.0.0 255.0.0.0 Null0
      • ip route 5.0.0.0 255.0.0.0 Null0
      • ip route 6.0.0.0 255.0.0.0 Null0
      • ip route 7.0.0.0 255.0.0.0 Null0
      • ip route 8.0.0.0 255.0.0.0 Null0
      • ip route 10.0.0.0 255.0.0.0 Null0
      • ip route 11.0.0.0 255.0.0.0 Null0
      • ip route 100.0.0.0 255.0.0.0 Null0
      • ip route 101.0.0.0 255.0.0.0 Null0
      • ip route 102.0.0.0 255.0.0.0 Null0
      • ip route 141.100.0.0 255.255.0.0 Null0
      • ip route 141.108.0.0 255.255.0.0 Null0
      • ip route 142.100.0.0 255.255.0.0 Null0
      • ip route 143.100.0.0 255.255.0.0 Null0
      • ip route 144.100.0.0 255.255.0.0 Null0
      • ip route 145.100.0.0 255.255.0.0 Null0
      • ip route 146.100.0.0 255.255.0.0 Null0
      • ip route 147.100.0.0 255.255.0.0 Null0
      • ip route 148.100.0.0 255.255.0.0 Null0
      • ip route 149.100.0.0 255.255.0.0 Null0
    • The ISP has provided you with the following next hop address and your local AS number.
      • R1 serial interface S0/0 is 171.108.1.1/30 AS-1024.
      • R1 serial interface S0/1 is 171.108.1.5/30 AS-1024.
    • Configure EBGP on R1 and verify the all advertised routes from ISP1 and ISP2 are present in R1’s BGP table.

 Policy Routing:

Using policy based routing ensures that all traffic sent from R3 meets the following criteria:  

  •  
    • All internet traffic sent to the default 0.0.0.0 is sent through R1.
    • All ICMP traffic is sent through R2.
    • All other traffic is sent through R1.

Attribute Modifications:

Configure R1 to set the following attribute for networks from ISP1 and ISP2.  

  •  
    • Prepend all networks in the range of 1.0.0.0 to 9.0.0.0 with the AS Path 400, 300, 200 and the origin attribute incomplete.
    • Set the weight of all networks received from ISP1 to 100 and ISP2 to 200.
