Hi,

I’m looking for information how to implement vRouter hardware offload with ConnectX-5 EN especially with OpenContrail? I find on [http://www.mellanox.com/related-docs/prod\_adapter\_cards/PB\_ConnectX-5\_EN\_Card.pdf](http://www.mellanox.com/related-docs/prod_adapter_cards/PB_ConnectX-5_EN_Card.pdf) _[http://www.mellanox.com/related-docs/prod\_adapter\_cards/PB\_ConnectX-5\_EN\_Card.pdf](http://www.mellanox.com/related-docs/prod_adapter_cards/PB_ConnectX-5_EN_Card.pdf)_ that offload is supported.

Best regards,

Hi,

For now, there’s no integrated solution with Contrail.

Look at our solution of ASAP^2 for OVS offload

Getting started with Mellanox ASAP^2 _[https://community.mellanox.com/s/article/getting-started-with-mellanox-asap-2](https://community.mellanox.com/s/article/getting-started-with-mellanox-asap-2)_

If you need further help, please open a case.

Regards

Marc

Hi Marc,

Do you mean that product brief has over promising mistake? Contrail cannot use OVS.

Hi Marc,

What is the best way to run Contrail vRouter on HCI environment where kernel will use same bonded ConnectX-5 EN ports with vRouter. I want to achieve maximum possible offload of ConnectX-5? SR-IOV, DPDK, SR-IOV + DPDK or else? If related to SR-IOV, should I use it with PF or VF?

Best regards,
