RARE user and assistance email list

[Xavier Jeannin <>]

Hello Csaba,

It is Tomasz that is making performance test to validate L2 PPN use 
case. The idea here was to demonstrate the interest of performance 
validation test for a potential user of new architecture like 
FreeRtr/RARE with P4 forwarding chipset.
He already completed several performance tests.
I let Tomasz answer for the configuration of the Poznan switch.

On my side for L2 PPN use case, I was on other projects that I had to 
complete first, I will start the work during the autumns on another switch.

Regards
Xavier
