ACL for applying over VLAN

[Alok_Shukla]

We have 4 VLAN over Core Switch (MLAG configured)
VLAN 1: 10.3.1.0
VLAN 2: 10.3.2.0
VLAN 3: 10.3.3.0
VLAN 4: 10.3.4.0

we don't want VLAN-3 and VLAN-2 to communicate with VLAN-1.
But VLAN-2 and VLAN-3 should communicate each other.
Help to apply me what ACL should be applying?

It's not working, still pinging both VLAN

[Alok_Shukla]

yes, we had applied on ingress direction but still, both VLAN can ping each other.

Note If an ACL needs to be installed for traffic that is L3 routed, and the ingress/egress ports are on different packet-processing units or different slots, and any of the following features are enabled, we recommend that you install the policy on a per-port basis rather than applying it as a wildcard, or VLAN-based ACL. • MLAG (Multi-switch Link Aggregation Group) • PVLAN • Multiport-FDB (forwarding database)

** count Corp_Vlan_3 in last statement.
I also doing first time so it could be wrong , but it should work.
