SD-WAN - vEdge

vEdge is the software or hardware routers at your sites and responsible for the data plane of the SD-WAN. vEdge routers connect to a vSmart controller through a Datagram Transport Layer Security (DTLS) connection. If you want to use hardware, you have the following options:

• Viptela vEdge: 100, 1000, 2000, or 5000 series routers.
• Cisco ISR and ASR: the IOS XE SD-WAN software image allows you to use Cisco SD-WAN on the ISR 1000, ISR 4000, and ASR 1000 series. These devices are often referred to as cEdge devices.
• Cisco ENCS: similar to the ISR series, you can use the IOS XE SD-WAN software images for the ENCS 5000 series platform.

If you want to use software, you have two options for VMs:

• vEdge Cloud
• Cisco Cloud Services Router (CSR)
