When considering the nature of Ethernet VPN (EVPN), it plays a vital role in providing advanced features for Ethernet services over a wide area network (WAN). Focusing on the merits of the chosen statement, it's established that EVPN facilitates efficient route exchange among Providers (PEs), allowing them to discover their peers. This process also supports the election of a Designated Forwarder (DF), a crucial aspect for load balancing and redundancy within the network.

The exchange of EVPN routes is instrumental in establishing and maintaining a loop-free topology, ensuring that traffic paths are optimal and resilient. The selection of a DF ensures that only one device forwards traffic for the same broadcast domain, which minimizes unnecessary congestion and enhances performance.

The other statements, while referencing different attributes of EVPN, do not encapsulate the primary functions of the technology as effectively. For instance, while it is true that EVPN can convey VLAN membership and MAC reachability, these features are part of a broader set of functionalities that EVPN offers without being as central as the discovery process among PEs and the DF election. Thus, focusing on peer discovery and DF election accurately highlights the critical operational dynamics of EVPN in a typical deployment scenario.
