Viptela FEC?

Hi,

 

I've searched Cisco's SD-WAN page and the internet and can't seem to find a definitive answer.  Does Viptela have error correction?  If so, what kind?  ARQ?  FEC?

it uses Forward error correction (FEC)

We have FEC as well as we are getting packet duplication by this month end 18.4, on the vEdge devices.  On cEdge its going to be available from March: Two modes: FEC Adaptive (enabled based on measured loss) and FEC Always (enabled on all packets)

@prastrip Am I correct in saying that FEC is enabled on vEDGE appliances only at the minute? This is not currently available on ISR devices running IOS XE SD-WAN?
