The exhibit shows that Host-1 and Host-2 are attached to the switch and associated with RVI vlan.1. However, traffic sent from Host-1 to Host-2 is not blocked as expected.
Why is this problem occurring?
Intra-VLAN traffic cannot blocked by a router-based filter.
The Block-Host-2 term does not contain the MAC address of Host-2.
The block-host filter is applied in the wrong direction of the vlan.1 interface.
Inter-VLAN traffic cannot blocked by a router-based filter.
