ADVPN 2.0 edge discovery and path management

The SD-WAN with ADVPN solution has evolved to version 2.0 with major changes to ADVPN design and operation, including the introduction of edge discovery and path management for ADVPN spokes.

ADVPN 2.0 incorporates intelligence into the spokes to ensure shortcut tunnels (also known as shortcuts) are established using underlays available on both spokes and chosen based on matching certain link health criteria.

ADVPN 2.0 provides a more flexible SD-WAN solution than the original ADVPN to achieve resiliency against underlay outages or degraded underlay performance because it no longer depends on specific BGP routing designs or mechanisms, including route reflection, BGP next hop recursive resolution, BGP per overlay, and BGP on loopback.

Currently, ADVPN 2.0 only supports IPv4.
