  Lab Simulation Question - EIGRP

  Correct Answer. Check the answer below
  Check the answer below

  First we should check the configuration of the ENG Router. Click the console PC “F” and enter the following commands.

  ENG> enable

  Password: cisco ENG# show running-config Building configuration... Current configuration : 770 bytes ! version 12.2 no service timestamps log datetime msec no service timestamps debug datetime msec no service password-encryption ! hostname ENG ! enable secret 5 $1$mERr$hx5rVt7rPNoS4wqbXKX7m0 ! interface FastEthernet0/0 ip address 192.168.77.34 255.255.255.252 duplex auto speed auto ! interface FastEthernet0/1 ip address 192.168.60.65 255.255.255.240 duplex auto speed auto ! interface FastEthernet1/0 ip address 192.168.60.81 255.255.255.240 duplex auto speed auto ! router eigrp 22 network 192.168.77.0 network 192.168.60.0 no auto-summary ! ip classless ! line con 0 line vty 0 4 login ! end

  ENG#

  From the output above, we know that this router was wrongly configured with an autonomous number (AS) of 22. When the AS numbers among routers are mismatched, no adjacency is formed.

  (You should check the AS numbers on other routers for sure)

  To solve this problem, we simply re-configure router ENG router with the following commands:

  ENG# conf t ENG(config)# no router eigrp 22ENG(config)# router eigrp 222ENG(config-router)# network 192.168.60.0ENG(config-router)# network 192.168.77.0ENG(config-router)# no auto-summaryENG(config-router)# endENG# copy running-config startup-config

  Second we should check the configuration of the MGT Router. Click the console PC “G” and enter the following commands.

  MGT> enable Password: cisco MGT# show running-config

  Building configuration... Current configuration : 1029 bytes ! version 12.2 no service timestamps log datetime msec no service timestamps debug datetime msec no service password-encryption ! hostname MGT ! enable secret 5 $1$mERr$hx5rVt7rPNoS4wqbXKX7m0 ! interface FastEthernet0/0 ip address 192.168.77.33 255.255.255.252 duplex auto speed auto ! interface Serial0/0 ip address 192.168.36.13 255.255.255.252 clock rate 64000 ! interface Serial0/1 ip address 192.168.60.25 255.255.255.252 clock rate 64000 ! interface Serial1/0 ip address 198.0.18.6 255.255.255.252 ! interface Serial1/1 no ip address shutdown ! interface Serial1/2 no ip address shutdown ! interface Serial1/3 no ip address shutdown ! router eigrp 222 network 192.168.36.0 network 192.168.60.0 network 192.168.85.0 network 198.0.18.0 no auto-summary ! ip classless ip route 0.0.0.0 0.0.0.0 198.0.18.5 ! line con 0 line vty 0 4 login ! end

  MGT#

  Notice that it is missing a definition to the network ENG. Therefore we have to add it so that it can recognize ENG router

  MGT# conf t MGT(config)# router eigrp 222MGT(config-router)# network 192.168.77.0MGT(config-router)# endMGT# copy running-config startup-config

  Now the whole network will work well. You should check again with ping command from router ENG to other routers! In Short:

  ENG Router

  ENG>enable Password: cisco ENG# conf t ENG(config)# no router eigrp 22 ENG(config)# router eigrp 222 ENG(config-router)# network 192.168.60.0 ENG(config-router)# network 192.168.77.0 ENG(config-router)# no auto-summary ENG(config-router)# end ENG# copy running-config startup-config

  MGT Router

  MGT>enable

  Password: cisco MGT# conf t

  MGT(config)# router eigrp 222

  MGT(config-router)# network 192.168.77.0

  MGT(config-router)# end

  MGT# copy running-config startup-config

  Some Modification in Question

  After adding ENG router, no routing updates are being exchanged between MGT and the new location. All other inter connectivity for the existing locations of the company are working properly. But Internet connection for existing location

  including Remote1 and Remote2 networks are not working.

  Faults Identified:

  1.

  Incorrect Autonomous System Number configured in ENG router.

  2.

  MGT router does not advertise route to the new router ENG.

  3.

  Internet Connection is not working all stations.

  We need to correct the above two configuration mistakes to have full connectivity

  Steps:

  1.

  ENG Router: Change the Autonomous System Number of ENG

  2.

  Perimiter Router: Add the network address of interface of Permiter that link between MGT and ENG.

  3.

  Perimiter Router: Add default route and default-network.

  Check the IP Address of S1/0 interface of MGT Router using show running-config command. (The interfaced used to connect to the ISP) ! interface Serial1/0 ip address 198.0.18.6 255.255.255.252 ! For Internet sharing we have create a default route, and add default-network configuration. The IP address is 198.0.18.6/30. Then the next hop IP will be 198.0.18.5.

  ENG Router

  ENG>enable Password: cisco ENG# conf t ENG(config)# no router eigrp 22 ENG(config)# router eigrp 222 ENG(config-router)# network 192.168.60.0 ENG(config-router)# network 192.168.77.0 ENG(config-router)# no auto-summary ENG(config-router)# end ENG# copy running-config startup-config

  MGT Router

  MGT>enable

  Password: cisco MGT# conf t

  MGT(config)# router eigrp 222

  MGT(config-router)# network 192.168.77.0

  MGT(config-router)# exit

  MGT(config)# ip route 0.0.0.0 0.0.0.0 198.0.18.5

  MGT(config)# ip default-network 198.0.18.0

  MGT(config)# exit

  MGT# copy running-config startup-config

  Important:

  If you refer the topology and IP chart, the MGT router uses Fa0/0 to connect ENG router, S0/0 used to connect Remote1, and S0/1 used to connect Remote2.

  Refer to the command show running-config, the command #PASSIVE-INTERFACE will deny EIGRP updates to specified interface. In that case we need to use #no passive-interface to allow the routing

  updates to be passed to that interface. For example when used the #show run command and we see the output like below.

  !

  router eigrp 22

  network 192.168.77.0

  network 192.168.60.0 passive-interface FastEthernet 0/0 passive-interface Serial 1/0 no auto-summary ! Then the command would be

  MGT(config)#router eigrp 222MGT(config-router)#no passive-interface Fa0/0MGT(config-router)#end

  Also MGT router connect to the ISP router using Serial 1/0. If you seen passive-interface s1/0, then do not remove it using #no passive-interface s1/0 command.

• Question 389:

  Refer to the exhibit.

  

  Which two statements are true about interVLAN routing in the topology that is shown in the exhibit? (Choose two.)

  A. Router1 and Switch2 should be connected via a crossover cable.
  B. The FastEthernet0/0 interface on Router1 must be configured with subinterfaces.
  C. Router1 needs more LAN interfaces to accommodate the VLANs that are shown in the exhibit.
  D. Host E and host F use the same IP gateway address.
  E. Router1 will not play a role in communications between host A and host D.
  F. The FastEthernet0/0 interface on Router1 and the FastEthernet0/1 interface on Switch2 trunk ports must be configured using the same encapsulation type.
  B. The FastEthernet0/0 interface on Router1 must be configured with subinterfaces.
  F. The FastEthernet0/0 interface on Router1 and the FastEthernet0/1 interface on Switch2 trunk ports must be configured using the same encapsulation type.
