When Data Centers are in the same campus, a simple solution could be a VSX LAG between pairs of VSX switches that allows the extension of L2 domains:

The statement accurately describes a common and valid Data Center Interconnect (DCI) architecture for campus environments using Aruba VSX technology. A VSX Link Aggregation Group (LAG) can be established between two distinct VSX pairs, with one pair in each data center. This configuration creates a resilient, high-bandwidth, loop-free Layer 2 path between the data centers. This path functions as a trunk, enabling the seamless extension of VLANs and their corresponding broadcast domains across the two physical sites, which is a primary goal of L2 DCI.

This is a "True or False" question. The statement is factually correct according to official Aruba design principles. The alternative, "False," would be incorrect because this topology is a standard, supported, and relatively straightforward method for achieving Layer 2 DCI in a campus setting with Aruba CX switches. It leverages the core capabilities of VSX to provide multi-chassis redundancy for the interconnect link itself.

"Layer 2 DCI" section: "A simple solution for campus data centers is to extend the L2 domains between the two locations. This can be achieved by creating a VSX LAG between the pairs of VSX switches." The guide includes a diagram (Figure 3) illustrating this exact topology

labeling it as "VSX LAG for L2 DCI."

Edition: 1). This official vendor documentation describes the capabilities of VSX LAGs.

Chapter: "VSX LAGs

" Section: "Interconnecting two VSX pairs with a VSX LAG": This section states

"A VSX LAG can be configured between two different VSX pairs. This configuration is useful in a data center environment where a pair of VSX switches are in one rack and another pair of VSX switches are in another rack." This confirms that the fundamental technology for connecting two separate VSX clusters via a VSX LAG is a supported feature.
