SDEWAN CNF

SDEWAN is implemented as CNF based on OpenWRT and it will support below functionalities:

• Export Restful API interface to support configuration of MWAN3, Firewall & NAT, IpSec.
• Site-to-Site tunnels across edges & edges & central orchestrators and application managers

SDEWAN Service

SDEWAN service restful API provides the capability to list available SDEWAN services, get service status and execute service operation.

Common Error code:

MWAN3

OpenWRT MWAN3 configuration includes below sections:

• Global: common configuration special used to configure routable loopback address (for OpenWRT 18.06)
• Interface: define how each WAN interface is tested for up/down status
• Member: represents an interface with a metric and a weight value
• Policy: defines how traffic is routed through the different WAN interface(s)
• Rule: describes what traffic to match and what policy to assign for that traffic.

SDEWAN CNF will be created with Global and Interface sections initialized based on CNF allocated interfaces.

SD-EWAN MWAN3 CNF API provides support to get/create/update/delete MWAN3 Rule, Policy (with Member).

• Include: used to enable customized firewall scripts
• Zone: groups one or more interfaces and serves as a source or destination for forwardings, rules and redirects.
• Forwarding: control the traffic between zones
