Task 4: Determine the Summary Route for the HQ, EAST, and WEST LANs.
Step 1: List summary networks for the HQ, EAST, and WEST LANs in binary format.
HQ Summary Route
1 0 1 0 1 1 0 0 . 0 0 0 1 0 0 0 0 . 0 1 0 0 0 0 0 0 . 0 0 0 0 0 0 0 0
EAST Summary Route
1 0 1 0 1 1 0 0 . 0 0 0 1 0 0 0 0 . 0 1 0 0 0 1 0 0 . 0 0 0 0 0 0 0 0
WEST Summary Route
1 0 1 0 1 1 0 0 . 0 0 0 1 0 0 0 0 . 0 1 0 0 0 1 1 0 . 0 0 0 0 0 0 0 0
Step 2: Count the number of left-most matching bits to determine the mask for the summary route.
1. How many left-most matching bits are present in the two networks?
21
2. What is the subnet mask for the summary route in decimal format?
255 . 255 . 248 . 0
