What is the difference between 'SD-WAN Layer 2 and Layer 3 routing - general' vs Advanced one?
Hi,
Can you please explain the main differences between the 'SD-WAN Layer 2 and Layer 3 routing - general' and 'Advanced SD-WAN Layer 2 and Layer 3 routing - general' features?
As a fan of this technology I am going to make my answer very simple, the issue in SDWAN is the protagonism, the IP addresses continue to exist like the famous network masks but they are no longer protagonists, the queen of the party is the applications for which the network is designed and built. So, like MPLS, there is routing but forwarding is based on labels and routing is to manage the equipment.

An interesting question is that I haven't seen an SD-WAN device that does not require an IP address at the edge.
You can connect your edge device to a layer 2 service (such as MPLS or VPLS), so we can assume this is the L2 methodology you are referring to.
However, you will still be required in most cases to apply an IP address so the solution would technically be seen as L3. Give that idea, also connecting an internet service to the same SD-WAN edge device would give you both L2 and L3 connectivity, but all L3 routing. Think of it this way: routing is done at L3.
The definition of Advanced Routing appears to be vendor-specific, where Cisco will tout DNA as being their Advanced SD-WAN with security. Other vendors may have different services they provide to define Advanced SD-WAN.
Hello community,
I am an Information Technology Domain Network and Solutions Architect at a large utility company.
I am currently researching SD-WAN solutions. Is the network connection for an SD-WAN router the same as a network connection to a traditional router? They both employ an ethernet private line for access, is that correct?
Thank you for your help.

More information please!! Of course it's not the same type of solution, but if you're talking about infrastructure, yes it's the same, you just need a patch cable (copper or fiber) from your ISP router connected to your router's WAN IN port.Otherwise, if you're talking about capabilities, it's normal behavior of the whole network to become slower if your UTM server is not good enough and that depends on how big your current and future network need is, take note of that, it is the main concern that you should focus on.Personal advice for you; go with a hardware kind router, most of the time it is a better solution and cheaper one, maybe you just don't know yet about the correct one for you, please let me know if I was helpful.
Hello peers,
I am a project and program manager at a medium-sized utility company.
I am interested in SD-WAN. Does anyone know what IBM focuses on within SD-WAN space?
Thank you.

IBM does not appear in Gartner's Magic Quadrant for SD-WAN as of the 12th September 2022.
One of my clients implemented Viptela which was later acquired by Cisco. They replaced about 30 MPLS circuits with multiple business broadband circuits, saved a lot of money, and increased speed and reliability.
According to Gartner's 2022 MQ report, the leaders are Fortinet, VMware, Cisco, HPE (Aruba), Versa, and Palo Alto.
