Thanks Csaba.

If I understand correctly, this will provide the point2point layer2, but I
won't be able to configure a management IP, right?
Anyway it seems fine for now.

Thanks for the update.

Assunto: Re: [RARE-users] Request to add BRIDGE to GEANT_TESTBED

hi,

tried to add the full bridging feature, which did not fit to the asic with
the below error message:

running /home/mc36/bf-sde-9.12.0/install/bin/bf-p4c -I. -I../p4src/
-Xp4c="--disable-parse-depth-limit" -DDUAL_PIPE optimizer1296.p4...
optimizer1296.tofino/pipe/optimizer1296.bfa:5550: error: tofino supports up
to 12 stages, using 14
optimizer1296.tofino/pipe/optimizer1296.bfa:0: error: Due to errors, no
binary will be generated failed command assembler returning false for 512 and
1024 on profile-geant-testbed
*** unable to find a working first value ***

but to provide just a point2point layer2, we have an other thing, which does
not involve bridging, but local cross-connect of two (sub)interfaces:
https://github.com/rare-freertr/freeRtr/blob/master/cfg/p4lang-rout215.tst#L58
and the good news is that adding this to the testbed profile compiled fine:

*** working profile generated successfully ***

i'l commit soon this to the bitbucket... then alex's automatism will pick it
up and do the final optimizations for both tofino1 and tofino2, then we'll
get a pull request with the new numbers... after accepting that, alex's
caches will start prebuilding with the new binaries...
it should not take more than a day... i'll keep you posted...

br,
cs
