I need help with isolation vlan from other vlans

Hello 

I have 3 vlans with each dhcp pool assigned , but i still can ping from vlan10 to vlan20 (i.e: can ping from 10.0.0.0 to 20.0.0.0 network and vice versa) same for vlan30 . How i can isolate each vlan alone please?

these are their configuration:

vlan 1
name "VLAN1"
no untagged 10-18
untagged 1-9,19-28
ip address dhcp-bootp
exit
vlan 10
name "vlan10"
untagged 10-12
ip address 10.0.0.1 255.255.255.0
dhcp-server
exit
vlan 20
name "vlan20"
untagged 13-15
ip address 20.0.0.1 255.255.255.0
dhcp-server
exit

vlan 30
name "vlan30"
untagged 16-18
ip address 30.0.0.1 255.255.255.0
dhcp-server
exit

Pools:

dhcp-server pool vlan10
HP-2620-24(vlan20)# authoritative
HP-2620-24(vlan20)# default-router 10.0.0.1
HP-2620-24(vlan20)# network 10.0.0.0 255.255.255.0
HP-2620-24(vlan20)# range 10.0.0.10 10.0.0.20

Hello,

If you want to stop all intervlan communication then disable 'ip routing' or you want to isolate some particular vlans then apply ACL.

Thanks!
