Part 1: Investigate IPv4 Directly Connected Routes
Part 2: Investigate IPv6 Directly Connected Routes

1.3.2.5 Packet Tracer – Investigating Directly Connected Routes Background

The network in the activity is already configured. You will log in to the routers and use show commands to discover and answer the questions below about the directly connected routes.
Note: The user EXEC password is cisco and the privileged exec password is class.

Part 1: Investigate IPv4 Directly Connected Routes

Step 1: Use show commands to gather information about the IPv4 directly connected networks.
Enter the following command on R1:



R1> show ip route ?

a. What option would be most beneficial in determining the networks assigned to the interfaces of the router? connected
b. Which networks are directly connected on R1? Hint: Use the option determined above.

C 172.31.20.0/23 is directly connected, GigabitEthernet0/0
C 172.31.22.0/23 is directly connected, GigabitEthernet0/1
C 209.165.200.224/30 is directly connected, Serial0/0/0

c. Which IP addresses are assigned to the LAN interfaces on R1?

d. Which networks are directly connected on R2?

C 172.31.24.0/24 is directly connected, GigabitEthernet0/0
C 172.31.25.0/24 is directly connected, GigabitEthernet0/1
C 209.165.200.224/30 is directly connected, Serial0/0/0

e. Which IP addresses are assigned to the LAN interfaces on R2?

Step 2: Verify PC addressing and test connectivity.
a. Open a command prompt on PC1. Issue the command to display the IP settings. Based on the output, would you expect PC1 to be able to communicate with all interfaces on the router? Provide a short answer describing your expectations.

The PC has the correct gateway address and the router lists all of the connected networks in the routing table.

Open a command prompt on PC2. Issue the command to display the IP settings. Based on the output, would you expect PC2 to be able to communicate with PC1? Verify your expectations.

Ping is successful

b. Determine the IP addresses of PC3 and PC4. Record the results and determine if PC3 and PC4 are able to communicate.

PC3 – IP address 172.31.24.10, PC4 – IP address 172.31.25.10

Test connectivity from PC1 to PC3. Was the test successful? Yes
c. Bonus: Looking at the outputs of the routing tables on R1 and R2, what might indicate a reason for the success or failure of communication between PC1 and PC3? The default static route 0.0.0.0/0

Part 2: Investigate IPv6 Directly Connected Routes

Step 1: Use show commands to gather information about the IPv6 directly connected networks.

a. Which IPv6 networks are available on R1?

b. Which IPv6 unicast addresses are assigned to the LAN interfaces on R1?

L 2001:DB8:C001:1::1/128 [0/0]
via ::, GigabitEthernet0/0
L 2001:DB8:C001:2::1/128 [0/0]
via ::, GigabitEthernet0/1

c. Which IPv6 networks are available on R2?

C 2001:DB8:C001:3::/64 [0/0]
via ::, GigabitEthernet0/0
L 2001:DB8:C001:3::1/128 [0/0]
via ::, GigabitEthernet0/0
C 2001:DB8:C001:4::/64 [0/0]
via ::, GigabitEthernet0/1
L 2001:DB8:C001:4::1/128 [0/0]
via ::, GigabitEthernet0/1
C 2001:DB8:C001:ACE::/64 [0/0]
via ::, Serial0/0/0
L 2001:DB8:C001:ACE::2/128 [0/0]
via ::, Serial0/0/0

d. Which IPv6 addresses are assigned to the LAN interfaces on R2?

L 2001:DB8:C001:3::1/128 [0/0]
via ::, GigabitEthernet0/0
L 2001:DB8:C001:4::1/128 [0/0]
via ::, GigabitEthernet0/1

Step 2: Verify PC settings and connectivity.
a. Open a command prompt on PC1. Issue the command to display the IPv6 settings. Based on the output, would you expect PC1 to be able to communicate with all interfaces on the router? Provide a short answer describing your expectations

The PC has the correct gateway address using the link local address on the router and the router lists all of the connected networks in the routing table.

b. Open a command prompt on PC2. Issue the command to display the IPv6 settings. Based on the output, would you expect PC2 to be able to communicate with PC1? Verify your expectations.

Ping is successful

c. Determine the IPv6 addresses of PC3 and PC4. Record the results and determine if PC3 and PC4 are able to communicate.

PC3 – IP address 2001:DB8:C001:3::10/64, PC4 – IP address 2001:DB8:C001:4::10/64

Test connectivity from PC1 to PC3. Was the test successful? Yes
d. Bonus: What might indicate a reason for the success or failure of communication between PC1 and PC3 after looking at the outputs of the IPv6 routing tables on R1 and R2? The default IPv6 static route

S ::/0 [1/0]
via ::, Serial0/0/0
