L2 and L3 EVPN Multi-homing

A host connects to multiple PEs by means of multi-homing.

Which of the following is NOT a function of the EVPN route-type 4 route?

  • A Allows the other PEs to discover which PEs are connected to the same Ethernet segment.
  • B Triggers the election of a designated forwarder.
  • C Identifies the type of algorithm to be used in the election process.
  • D Identifies the redundancy mode of the Ethernet segment.
Explanation

An EVPN Ethernet Segment route (route type 4) provides multihomed-PE discovery and participates in designated-forwarder election; its DF Election Extended Community can signal the desired election algorithm. All-Active versus Single-Active redundancy mode is instead signaled by the Single-Active flag in the ESI Label Extended Community carried with an Ethernet Auto-Discovery per Ethernet Segment route (route type 1).
