Cisco SD-WAN routers deliver the WAN, security, and multicloud capabilities of the SD-WAN architecture.
The Cisco SD-WAN routers are available as hardware, software or cloud routers that sit at the perimeter of a site.
SD-WAN routers support standard features such as OSPF, BGP, ACLs, QOS and other routing policies.
In addition to the SD-WAN control and data plane functions, the SD-WAN router automatically establishes a secure DTLS tunnel with the vSmart controller and forms an OMP neighbourship to exchange routing information.
The SD-WAN router will also establish IPSec tunnels with other SD-WAN routers in the fabric.
SD-WAN routers have added intelligene to make site-local decisions regarding routing, high availability, interfaces, ARP, and ACLs.
There are two different types of SD-WAN routers available, cEdge and vEdge
A vEdge router is the original Viptela platform running the Viptela software.
A cEdge router is the Viptela software with Cisco additions and part of IOS-XE. It is supported on the CSR, ISR, ASR1K, ENCS, and the cloud CSRv and ISRv routers too.
The vManage controller can enable provisioning, configuration and troubleshooting of vEdge routers in the same way that it does for cEdge routers.
There are some features on cEdge routers that are not available on vEdge routers: Cisco AMP and AMP threat grid, URL filtering, Snort intrusion prevention system, and embedded platform security.
The enterprise firewall and Umbrella DNS security is available on both platforms.
