Inter Vlan related querry

Hi Team, I have created Vlans in Single L3 Switch and provided each different vlan different IP DHCP Pool and IP address range and they are pinging each other by default what should i do for not communicating each other, any resolution anyone know? without ACL’s

You can use VRF’s if you want to segregate them from each other.

like
!
ip vrf myvrfvlan10
!
int vlan 10
ip vrf forwarding myvrfvlan10
ip x,x,x,x

ip dhcp pool vlan10
vrf myvrfvlan10

or use vlan ACL

VLAN ACLs (VACLs) (cisco.com)

Without ACL not possible or simply make l3 switch again l2 by giving the below command
