[chavankaustubh]

i have one 3750 series layer 3 switch & 4 vlans configured on it as follows :

Vlan 1
vlan 2
vlan 3
vlan 4

I want communication between vlan 2 & vlan 3 rest of others shud not be
communicate with each other so,when i put "ip routing" is that all other vlan will also communicate or not?

correct me if i m wrong.

if yes then how to block others please guide.

Thanks in advance..

When you enable "ip routing" on your switch, all vlans will communicate with each other by default unless you deploy VACL or use private vlans.
