A customer is using a legacy application that communicates at layer-2. The customer would like to keep this application working to a remote site connected via layer-3 All legacy devices are connected to a dedicated Aruba CX 6200 switch at each site.

What technology on the Aruba CX 6200 could be used to meet this requirement?

Suggested Answer: A

VXLAN is a technology that can be used to meet the requirement of using a legacy application that communicates at layer-2 across a layer-3 network. Static VXLAN is a feature that allows the creation of layer-2 overlay networks over a layer-3 underlay network using VXLAN tunnels. Static VXLAN does not require any control plane protocol or VTEP discovery mechanism, and can be configured manually on the Aruba CX 6200 switches. The other options are incorrect because they either do not support layer-2 communication over layer-3 network or are not supported by Aruba CX 6200 switches.

I thought GRE was mainly for tunneling, not sure about this one!

IMET could also be a good option, but not sure if it fits all needs.

Wait, are we sure EolP is compatible with legacy apps?

Definitely agree, EolP makes sense for layer-2 to layer-3!

I think Ethernet over IP (EolP) is the way to go here.

Static VXLAN sounds familiar, but I’m unsure if it’s the right choice for connecting legacy applications to a remote site.

I feel like IMET could be a possibility since it deals with multicast, but I need to double-check its compatibility with layer-3.

I remember practicing a question about GRE tunnels, but I can't recall if they apply to this scenario with legacy devices.

I think the answer might be Ethernet over IP, but I'm not entirely sure how it works with layer-2 applications.
