Exam NSE7_EFW-7.2 Topic 3 Question 49 Discussion

ADVPN (Auto Discovery VPN) is a feature that allows to dynamically establish direct tunnels (called shortcuts) between the spokes of a traditional Hub and Spoke architecture. The auto-discovery receiver must be set to enable on the spokes to allow them to receive NHRP messages from the hub and other spokes. NHRP (Next Hop Resolution Protocol) is used for on-demand tunnels, which are established when there is traffic between spokes. Routing is configured by enabling add-nhrp-route, not add-advpn-route.
