Location 1 has 10 layer 2 switches. Location 2 has 6 layer 2 switches. Location 3 has 8 layer 2 switches.
Location 1 has VLAN1 and VLAN2. Location 2 has VLAN2 and VLAN3. Location 3 had VLAN2 and VLAN4.
Each VLAN is in its own subnet.
There is a 3750 at each location. I want to do intervlan routing so workstations can connect across vlans at all locations.
Is this possible if I use IP Routing on all 3750 switches and if so, how are the trunks configured? Also, must the be ip addresses for all vlans on all switches or just for the vlans with corresponding subnets?
