Task 6: Determine the Summary Route for the Central
Portion of the Network
Use the networks in the list that follows to determine a summary route for the Central portion of the
network.
List the Central network segments in binary format.
Step 1.
CENTRAL LAN1:
11000000.10101000.00000110.00000000
CENTRAL LAN2:
11000000.10101000.00000110.10000000
Link from HQ to CENTRAL:
11000000.10101000.00000110.11000000
Count the number of leftmost matching bits to determine the mask for the summary route.
Step 2.
How many leftmost matching bits are present in the networks?
24
1.
What is the subnet mask for the summary route in decimal format?
255.255.255.0
2.
Copy the matching bits and then add all 0s to determine the summarized network address.
Step 3.
What is the summary route in binary form?
11000000.10101000.00000110.00000000
1.
What is the network address for the summary route in decimal format?
192.168.6.0
2.
Task 7: Determine the Summary Route for the N-EAST LANs
List the N-EAST LAN1 and LAN2 in binary format.
Step 1.
LAN1:

LAN2:
11000000.10101000.00000101.00100000
Count the number of leftmost matching bits to determine the mask for the summary route.
Step 2.
How many leftmost matching bits are present in the networks?
26
1.
What is the subnet mask for the summary route in decimal format?
255.255.255.192
2.
Copy the matching bits and then add all 0s to determine the summarized network address.
Step 3.
What is the summary route in binary form?
11000000.10101000.00000101.00000000
1.
What is the network address for the summary route in decimal format?
192.168.5.0
2.
Task 8: Determine the Summary Route for the SE-BR1 LANs
List the SE-BR1 LAN1 and LAN2 in binary format.
Step 1.
LAN1:

LAN2:
11000000.10101000.00000100.01000000
Count the number of leftmost matching bits to determine the mask for the summary route.
Step 2.
How many leftmost matching bits are present in the networks?
25
1.
What is the subnet mask for the summary route in decimal format?
255.255.255.128
2.
Copy the matching bits and then add all 0s to determine the summarized network address.
Step 3.
What is the summary route in binary form?
11000000.10101000.00000100.00000000
1.
