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.

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

It's a different switch chip for the CRS326-24S+2Q+RM (98DX8332) than for the other CRS326-24g-2S+RM (98DX3236)
Even on their webpage the PDF for the 98dx83xx series says that it suports NVRGE, VXLAN-GPE, GENEVE, SPB, and 802.1BR port extender. https://www.marvell.com/content/dam/mar ... 016-12.pdf

I might be missing something but doesn't that mean that the CRS326-24S+2Q+RM would support VXLAN with the 7.0beta5 release as well?

Having VxLAN support in HW on the CRS326-24S+2Q+RM would be just amazing.

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.

+1,000 (CRS326-24S+2Q+RM) If these really do VxLAN and we get EVPN so we can make them VTEP's
Instead of +1. We get to do it for the number of units we would potentially buy right?
While I'm putting together a wish list could we get a...
CCR1288-1G-8Q+RM
1U rackmount, 1x Gigabit Ethernet, 8xQSFP+ cages, LCD, 288 cores x 1GHz CPU, 64GB RAM, up to 480 million packets per second, 320Gbps throughput, RouterOS L7
???

Having VxLAN support in HW on the CRS326-24S+2Q+RM would be just amazing.

Low cost Municipal Fiber Open Network here we come!

i understand that we only have VXLAN itself... is it correct to assume it's working in flood and learn? is EVPN already supported?

Hey, dont forget us with current MT routers like the RB450Gx4 with the AR8327 switch chip. Can Router Os7 please have hw offload in vlan bridges extra pretty please.

I used the VxLAN lab from IPANetEngineer's example configuration post. VxLAN destroys my 951ui2hnd's 100% CPU at around 60Mb to 75Mb TCP.
Same lab with HAPAC2 is better I average 220Mb but it's not balancing across the CPU's. With my computer plugged into R1 when I'm downloading it uses 100% of one of the CPU's and almost nothing of the other three. On upload it is using 100% of the CPU on R3(To Internet) and almost nothing on the other CPU's.
Am I missing something or is there something I should be able to tweak?

I think it's just too early on to really expect much more than a software path on this. I would really like to see more down the pipe for sure, like some hardware decapsulation for switches and proper evpn support but it's a very cool toy to play with right now.

It is a cool toy to play with right now. Of course I want the hardware path in the future. I don't even mind the software only side for now...
I was just wondering if anyone had got it to work across more than one CPU?

CRS317 do.

Is there any prove that CRS317 do VxLAN in Hardware on the SwitchChips ASIC?

Because the documentation of ROS 6 and 7 do not tell anything about that. There is VxLAN flagged to be done on CPU only.

https://help.mikrotik.com/docs/display/ ... ng-Monitor

The detailed programming manuals for these ASICs are intended to be available only to those who have signed NDAs. Either someone is talking out of school, or they've gotten a copy of the reference books another way and are reporting what they've found.

The thing is, it doesn't matter which is the case. Even if the claim up-thread is correct, all he's claiming is that the chip at the core of the CRS317 can do VXLAN in hardware. This does not tell you that RouterOS currently programs the chip to do what you're asking, or if it does, that the programmed functionality meets your requirements.

You're free to ask MikroTik to support this feature, and they will decide what resources to put into it. The existence of ASIC-level support guarantees you nothing about how they will respond, how soon, or how well.

It’s not actually buried deep in reference material, it’s in the bullet point features on Marvell’s website for the chipset.

Yes, I was indeed ignoring the possibility that the public marketing slicks — the things they dare to call "datasheets" — had useful information on them. It's rare, but it does happen.

VXLAN on Tik is useless for professional use, as it doesn't support EVPN. Hardware/CPU or not.

DarkNate ... seems that Mikrotik is a guilty pleasure for you .... you hate it but you cannot live without it. If you are so disgusted you can just not read, not comment and leave the forum.

Please change your attitude ... please do look on the bright side of administrator life.

It looks like mikrotik is moving towards EVPN, it just has a number of components.

My only criticism here is that for most, it's not super useful without hardware accelleration.

Seeing the new CRS504-4XQ-IN that will be really cool.
Swtich-Chip: MARVELL® Prestera® 98DX4310 Multi-Layer Ethernet Switch

Also this switch supports

• Layer-2 Wire-Speed Switching engine with large MAC table
• Layer-3 Wire-Speed Routing engine with large LPM table
• CAPWAP overlay support
• Virtualization – IEEE 802.1Qbg EVB, 802.1BR Port Extender
• Virtual overlay networking – NVGRE, VXLAN-GPE, GENEVE, SPB, TRILL, GRE
• NFV Service Function Chaining – Network Service Header (NSH)
• SW compatibility to 98DX42xx, 98DX83xx, 98DX84xx, 98DX85xx

I hope we will see that HW-Offloading Implementation supported by ROS in the next new versions.

has there been any news on this from the devs?

would really love to see HW offloading support available on CRS326 for vxlan

So as there is no VxLAN with Hardware Offload available for CRS317, because of leak of software side support...

What is the correct way with CRS317 to tunnel sfpplus10 on SW#1 (CRS317) to sfpplus10 on SW#2 (CRS317) on Layer3 with wirespeed?
