Does created VLANs route by itself by default ? I have created few VLANs and it can communicate within each VLAN. Any idea ?

If it is anything like HP Procurve, all VLANs can talk to all VLANs by default.  You need to configure acls in the Layer3 switch to stop the hopping between VLANs.

The Layer3 switch automatically has a route map.  If it knows about all 3 VLAN's, it knows how to route them.  Apply ACLs to prevent traffic between them.

Have a look at: http://www.h3c.com/portal/Technical_Support___Documents/Technical_Documents/WLAN/Access_Controller/H3C_WX3000_Series_Unified_Switches/Configuration/Operation_Manual/H3C_WX3000_CG-6W103/201007/685290_1285_0.htm

specifically, Assigning an ACL to a VLAN.

This is a quick example I found googling:

acl number 3011
description Inbound vlan 11 traffic
rule deny ip source destination
rule permit ip source any
 now go into vlan interface 11 and apply the acl
int vlan 11
packet-filter 3011 inbound

You can find more here (message 10 has the full example): http://h30499.www3.hp.com/t5/Comware-Based/Can-we-restrict-routing-between-VLANs-in-A5120-using-ACL/td-p/5398109#.Vfjcc_lVhBc

on vlan-interface1
rule 10 deny ip source destination
rule 20 deny ip source destination
rule 30 deny ip source destination

on vlan-interface10
rule 10 deny ip source destination
rule 20 deny ip source destination
rule 30 deny ip source destination

so on interface 100, 200
