- for curriculum computers network in each room we
will create a VLAN and assign a subnet for IP addressing; assigning VLANs
will be done on switches and assigning subnets will be made on school's
Router using subinterfaces of the main interface for curriculum
LAN, Ethernet2
- VLANs and subnetting for each room are used so that broadcast
storms are avoided of affecting all curriculum network when broadcasts
happen.
