This feature adds support for associating a WAN interface with multiple Dynamic Path Selection (DPS) path groups to allow paths originating from the same interface to have different priorities.

DPS (Dynamic Path Selection) provides the ability to select different paths for different types of traffic to optimize application performance.

Support for IPSec connections in a full-cone Network/Port Address Translation (NAT) environment has been added to the Dynamic Path Selection (DPS) setup. DPS optimizes application performance by selecting different paths for various types of traffic. In this configuration, STUN is used to discover the translated IP address of WAN interfaces and export it to BGP.

This feature is used to connect a Layer 3 EVPN VXLAN network to an Adaptive Virtual Topology (AVT) WAN network using dynamic path selection (DPS) tunnels. One or a pair of WAN routers are configured to serve as the VXLAN gateway. On the control plane, the configured VXLAN gateway handles EVPN IP-PREFIX route exchanges between the VXLAN network and the WAN network. On the data plane, the configured VXLAN gateway decapsulates the VXLAN packets received from the VXLAN network and encapsulates them into the DPS tunnels and sends them to the AVT WAN network. 

STUN (Session Traversal Utilities for NAT) is a client-server protocol that can be used by a network endpoint to determine the IP address and port assigned to it by a NAT device. The protocol is defined in RFC8489.

This document describes the STUN client and server capabilities in CloudEOS, and how this is used by Dynamic Path Selection (DPS) feature.
