b. Record your subnet assignment in the table below.

• 1) Assign the first IPv4 address of each subnet to a router interface
  
  • (i) subnet A is hosted on R1 G0/0/1
  • (ii) subnet B is hosted on R1 G0/0/0
• 2) Assign the last IPv4 address of each subnet to the PC NIC
• 3) Assign the second IPv4 address of subnet A to S1
• 4) List the maximum number of useable hosts per subnet

c. Record the IP address information for each device:

d. Use the IPv6 address 2001:db8:acad::/48 and create two subnets for use in this network. Record the IPv6 addresses in the table.

e. Record the IPv6 address information for each device.
Note: Use FE80::1 as the link-local address on both router interfaces.

Before proceeding, verify your IP addressing scheme with the instructor.

Part 2: Initialize and Reload Devices

• Total points: 10
• Time: 20 minutes

• Erase the startup configurations and VLANs from the router and switch and reload the devices.
  On Switch
  

  Switch>enable
  Switch#erase startup-config
  Erasing the nvram filesystem will remove all configuration files! Continue? [confirm]
  [OK]
  Erase of nvram: complete
  %SYS-7-NV_BLOCK_INIT: Initialized the geometry of nvram
  Switch#delete vlan.dat
  Switch#reload
  Proceed with reload? [confirm]

  On Router

  Router>enable
  Router#erase startup-config
  Erasing the nvram filesystem will remove all configuration files! Continue? [confirm]
  [OK]
  Erase of nvram: complete
  %SYS-7-NV_BLOCK_INIT: Initialized the geometry of nvram
  Router#reload
  Proceed with reload? [confirm]
  Initializing Hardware ...
  
  Would you like to enter the initial configuration dialog? [yes/no]: no

• After the switch is reloaded, change the SDM template to one that supports IPv6 as necessary, and reload the switch again.
  On Switch:
  

  Switch>
  Switch>enable
  Switch#configure terminal 
  
  Switch(config)#sdm prefer dual-ipv4-and-ipv6 default
  Changes to the running SDM preferences have been stored, but cannot take effect until the next reload.
  Use 'show sdm prefer' to see what SDM preference is currently active.
  Switch(config)#exit
  
  Switch#reload

Before proceeding, ask your instructor verify device initializations.

S1(config)#banner motd #Unauthorized Access is Prohibited!#

S1(config)#crypto key generate rsa 
The name for the keys will be: S1.ccna-lab.com
Choose the size of the key modulus in the range of 360 to 2048 for your
  General Purpose Keys. Choosing a key modulus greater than 512 may take
  a few minutes.

How many bits in the modulus [512]: 1024
% Generating 1024 bit RSA keys, keys will be non-exportable...[OK]

S1(config)#interface vlan 1
S1(config-if)#description Switch Subnet A
S1(config-if)#ip address 192.168.10.2 255.255.255.128
S1(config-if)#ipv6 address FE80::2 link-local 
S1(config-if)#ipv6 address 2001:db8:acad:a::2/64
S1(config-if)#no shutdown 
S1(config-if)#exit

S1(config)#ip default-gateway 192.168.10.1

Part 4: Test and Verify End-to-End Connectivity

• Total points: 15
• Time: 10 minutes

Use the ping command to test IPv4 and IPv6 connectivity between all network devices.
Note: If pings to host computers fail, temporarily disable the computer firewall and retest.
Use the following table to methodically verify connectivity with each network device. Take corrective action to establish connectivity if a test fails:

In addition to the ping command, what other command is useful in displaying network delay and breaks in the path to the destination? (1 point)
tracert or traceroute

Part 6: Cleanup

NOTE: DO NOT PROCEED WITH CLEANUP UNTIL YOUR INSTRUCTOR HAS GRADED YOUR SKILLS EXAM AND HAS INFORMED YOU THAT YOU MAY BEGIN CLEANUP.

Unless directed otherwise by the instructor, restore host computer network connectivity, and then turn off power to the host computers.

Before turning off power to the router and switch, remove the NVRAM configuration files (if saved) from both devices.

Disconnect and neatly put away all LAN cables that were used in the Final.

Router Interface Summary Table

Note: To find out how the router is configured, look at the interfaces to identify the type of router and how many interfaces the router has. There is no way to effectively list all the combinations of configurations for each router class. This table includes identifiers for the possible combinations of Ethernet and Serial interfaces in the device.

The table does not include any other type of interface, even though a specific router may contain one. An example of this might be an ISDN BRI interface. The string in parenthesis is the legal abbreviation that can be used in Cisco IOS commands to represent the interface.
