- - - - Part 4 IP Address - - - -

4.1 IP addressing calculation for Fantastic Gaming Café network:

The network address is 200.168.0.0

Wireless guest subnet: 90 hosts  

Gaming PC subnet: 40 hosts  

Printing subnet: 6 hosts 

Admin subnet: 3 hosts 

Create 4 VLANs to separate 4 different purpose subnet :

Firstly, wireless guest subnet requires 90 hosts, 32 - 25 = 7 ,  2^7 = 128 hosts , so subnet mask /25 enough for supporting the 90 hosts. Secondly, gaming pc subnet requires 40 hosts, 32 - 26 = 6 ,  2^6 = 64 hosts , so subnet mask /26 enough for supporting the 40 hosts. Thirdly, printing subnet requires 6 hosts, 32 - 28 = 4 ,  2^4 = 16 hosts , so subnet mask /28 enough for supporting the 6 hosts. Lastly, administration subnet requires 3 hosts only, 32 - 29 = 3 ,  2^3 = 8 hosts , so subnet mask /29 enough for supporting the 3 hosts.

HSRP configuration is applied to both the core and distribution layers of the hierarchical network. For example, the G1/0/0 interface of CoreRTR1 is assigned the IP address 200.168.0.2/29, and the G1/0/1 interface of CoreRTR2 is assigned the IP address 200.168.0.3/29. The virtual IP address for both interfaces is set to 200.168.0.1, which will be used as the default gateway for other connected devices. If one of the routers or the associated link fails, the other router will automatically take over the routing tasks immediately. The distribution layer use same of theory of work.
