After testing a new HPE Aruba Networking 6200M switch deployment for a small office, you discovered that hosts in different VLANs cannot reach each other.
What do you need to configure to enable connectivity between VLANs?
The correct answer is A. Configure an SVI for each VLAN. Hosts in different VLANs are in different Layer 2 broadcast domains, so they cannot communicate directly through normal switching alone. To enable communication between VLANs, the switch must provide Layer 3 gateway interfaces for those VLANs. On HPE Aruba Networking CX switches, this is done with switched virtual interfaces, or SVIs, using interface vlan < VLAN-ID > and assigning an IP address to each VLAN interface. HPE Aruba Networking documentation shows Layer 3 VLAN interfaces using interface vlan with an IP address, and also refers to an SVI as the Layer 2 VLAN interface IP address used by the switch. Option B is not the best answer because simply enabling IP forwarding does not create gateway interfaces for the VLANs. Option C is incorrect because trunking VLANs to another Layer 2 switch only extends VLANs; it does not route between them. Option D is incorrect because VLANs separate Layer 2 domains, and inter-VLAN communication requires routing, not bridging.
