Hello All,

In EVPN MH with Single-Active scenario, could you help us to clarify the below 
query?

                     --------------

Let's say CE1 is connected to PE1 and PE2 (single-active case)
and PE1 is the DF for VLAN 10 and has the active link,
but CE1 sends unknown unicast traffic on the link to PE2 (standby link),
wouldn't the traffic be dropped because its non-DF ?

or

How does CE ensure traffic is always forwarded on the active link
(as standby link will drop the traffic) ?

Thanks & Regards
Jaikumar S
