Task 4: Determine the Summary Route for the Northwest
Portion of the Network
Use the networks listed here to determine a summary route for the Northwest portion of the network.
List the Northwest network segments in binary format.
Step 1.
NW-BR1 summary:
11000000.10101000.00000111.10000000
NW-BR2 summary:
11000000.10101000.00000111.11000000
Link from N-WEST to NW-BR1:
11000000.10101000.00000111.11100000
Link from N-WEST to NW-BR2:
11000000.10101000.00000111.11100100
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?
11000000.10101000.00000111.10000000
1.
2.
What is the network address for the summary route in decimal format?
192.168.7.128
Task 5: Determine the Summary Route for the West Portion
of the Network
Use the networks in the list that follows to determine a summary route for the West portion of the network.
List the West network segments in binary format.
Step 1.
S-WEST summary:
11000000.10101000.00000111.00000000
N-WEST summary:
11000000.10101000.00000111.10000000
Link from WEST to N-WEST:
11000000.10101000.00000111.01000000
Link from WEST to S-WEST:
11000000.10101000.00000111.01000100
Link from HQ to WEST:
11000000.10101000.00000111.01001000
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?
11000000.10101000.00000111.00000000
1.
What is the network address for the summary route in decimal format?
192.168.7.0
2.
