VLAN testing

cny2009
I have try a testing between 3com 4500 L3 switch and 3com 4210 switch. I create 3 VLAN and IP interface for each of them in 4500.

V1: 128.1.1.1/16
V2: 128.2.1.1/16
V3: 128.3.1.1/16

I create a trunk between the switches, so the PC in same VLAN but different switch can ping to each other.

How can i let the PC in VLAN 2 can ping to VLAN 3?
