Re: [vpp-dev] how to punt a specific TCP flow into linux kernel?

[Vijay Katamreddy (vkatamre)]

Hi

One of the way I see as follows:

With the recent changes I rolled up, all the TCP Packets not handled in VPP’s 
TCP stack would be punted via IP4/6_punt path.
In the punt path, you could configure such that ip4/6_punt traffic to a 
specific Next hop/Interface.

Thanks
Vijay

Hi Lin, 

You can punt all tcp traffic without state in the stack with "set punt tcp”. 
You’ll also have to enable the session layer for that to work with “session 
enable”. Finally, the simplest way to get the traffic into linux is to add to 
vpp’s startup.conf tuntap { enable }.

Hope this helps, 
Florin
