BasicInternet:Infrastructure extension

= Extending the Basic Internet Network = note on use of ASA: each simple router will do the job, need to be adapted based on the capacity to handle

Option 1: DHCP for each sub-network


Provide each University (or even parts of a University) with an own sub-network.
 * Requires a path from Mikrotik to one ASA

ASA providing different DHCP, f. eks. 172.16.x.x for University A, and 172.16.x.x for University B
 * class B: 172.16.x.x (16 bit for networks, 16 bits for end network - max 65000 users per network)
 * example: need for 5.000 IP addresses = 13 bits for end users, rest for network (20.000 students, 5.000 every day)
 * class A: 10.x.y.z/8 - 8 bit for the network, 24 bits for the end users (> 2million end users)
 * class C: 192.168.1.x/24 - 24 bits for network, and 8 bits for end devices (255 devices)
 * new: supports also classless...

Option 2: Tunnel from each ASA


Central infrastructure with one ASA
 * each site has an own ASA providing DHCP
 * on-site ASA has a VPN back to the central ASA
