Actual exam question for Juniper's JN0-683 exam
Question #: 95
Topic #: 4
Why is a designated forwarder required in a multihomed CE-to-PE VXLAN environment using EVPN signalling?

Suggested Answer: D Vote an answer

The designated forwarder is required to prevent duplicate packets from being received on multihomed hosts: In a multihomed CE-to-PE VXLAN environment using EVPN signaling, a host may be connected to more than one PE. Without a designated forwarder, both PEs could forward the same broadcast, multicast, or unicast traffic to the multihomed host, leading to duplicate packets. The designated forwarder ensures that only one PE forwards traffic to the host, preventing this issue.
