Which of these statements regarding multi-homing in EVPN is FALSE?

  • A Type 1 Ethernet Auto-Discovery (A-D) EVPN route is used to support EVPN multi-homing.
  • B Type 4 Ethernet Segment (ES) EVPN route is used for designated forwarder (DF) election for an ES.
  • C The ES identifier (ESI) uniquely identifies an ES and it is locally significant for a particular leaf.
  • D The Ethernet Segment (ES) identifies a set of links that connects a host to one or more leafs.
Explanation

An Ethernet Segment Identifier (ESI) identifies a multihomed Ethernet Segment and is intended to be unique across the EVPN network. Network-wide ESI uniqueness enables Ethernet Segment auto-discovery and Designated Forwarder election, so an ESI is not locally significant to a particular leaf.
