interVLAN Routing

[admin_2]

Hi all,

I have create 4 vlans from 1 to 4 (on a catalyst 3550),

and 4 svi to enable routing. actually all vlan could communicate with each other, but i want to restrict communication only between 1-2,1-3,1-4 but not between others.

How could i do that ??

I would just use ACLs.

You could an ACL and put it on the SVI for VLAN 1 outbound and another ACL inbound.

More info on 3550 ACLs:
