vxlan performance?

Sat Feb 15, 2020 1:09 am

Will vxlan have a fast-path option for hardware accelleration? I'm seeing some overhead in a VM with bandwidth test over vxlan right now. I know it's early, but this is a very interesting subject matter for me.

The Marvell PresteraDX chips in the CRS3xx series switches can do VXLAN in hardware, so offload is technically possible. It's up to MT to actually implement it in RouterOS.

yeah, CRS3xx and Routeros7 with vxlan is a game changer... The prospect of this really puts some other hardware purchases in jeopardy.

Agreed. If we see EVPN added to BGP to support VxLAN in the future, MikroTik will see a massive increase in sales from people who need inexpensive devices to act as a VTEP.

Evan just vxlan and Bridges is awesome if the crs3xxx line can bridge the vxlan to a port in hardware, but full EVPN kit would be stellar.

There is nothing in this price range by a mile.

Not all CRS3xx hardware has VXLAN support in the ASIC.

CRS309 and CRS317 do.

CRS326 and CRS354 do not.

Interesting. So the 98DX82xx ASICs do VXLAN, but the 98DX32xx & 98DX83xx don't? I can't find that anywhere, and on the main PresteraDX page Marvell seems to claim VXLAN support for the entire PresteraDX family. Where did you find that it's not that simple?

Hardware Office VXLAN on CRS326-24S+2Q+RM would be amazing.
