hi,
not yet... you can try to achieve this, should not be a big deal to pass
0..23 to pipe0 and 24..32 to the rest to pipe1,
but how the heck would you decide that you have to match against to the pipe1
without doing so? :)
yet an other issue is that crossing the pipe boundary means recirculation,
which is, a looped back port,
that is, you limit the whole box to somewhat 100gbps of performance with such
packets....

Bonjour Fr d ric!

Have you or anyone in the project considered or suggested exploring a "folding
pipeline" architecture in RARE for expanded LPM memory?

I have a (dual pipeline, Ufispace S9180) Tofino, at last! I've been commissioned to
evaluate the platform as a "basic" provider edge / peering router for Packet
Clearing House (pch.net). Table memory is a priority, as you might imagine. With the
FreeRTR control plane being extraordinarily feature complete, and the continuous
testing from the RARE project...I'd like to validate this for recommendation to
production -- but I need more routes!

I am stuck in the US at present but return to CET in two weeks. Perhaps,
schedule permitting, we could catch up? Email always works too, in these busy
times :-)

Best,
