CCNA 2 - An assignment on VLSM 2008-07-05 17:10:00 Question: Perform subnetting with the given address 180.180.0.0/16 as the address for the following topology: Solution: To perform subnetting with VLSM (concerning minimal wastage of host address) we will assign network address for various lans (in the given topology) sequentially, as follows: a. Lan 1 : 8000 hosts b. Lan 4 : 4000 hosts c. Lan 5 : 4000 hosts d. Lan 2 : 2000 hosts e. Lan 3 : 1000 hosts f. Lan 6: 500 hosts g. Lan 7 : 254 hosts h. Lan 8 : 50 hosts a. Lan 1 : 8000 hosts: We will use base address 180.180.0.0/16 to subnet for supporting 8000 hosts. We have to borrow 3 bits from the host portion for such subnetting. There will be 23 =8 subnet each of which will have the subnet mask: 255.255.224.0. So, Block size = (256-224) = 32 (network size). The subnets are: Subnet 0: 180.180.0.0/19 Subnet 1: 180.180.32.0/19 Subnet 2: 180.180.64.0/19 Subnet 3: 180.180.9 ...
