Hello Alexandre,
That's very helpful numbers.
I'll check when I can get my hand on a test machine.

Hello Nicolas,
We are using BIRD as route reflector in addition to Juno’s VRR (need some
feature like ORR)
The version that we use is 2.0.7 hosted on hypervisor and the VM has:
- RAM: 24G
- CPU: 8vCPU (Xeon CPU)
We have around 30 IPv4 sessions and 30 IPv6 sessions (per instance of Bird)
The memory used is 2G
The number of routes is +9M IPv6 and +1.6M IPv6
Feature used:
- Multiple table
- OSPF
- AF v4/v6 unicast
- BGP add-path
Computation and convergence are quite ok.
From my experience, we never had issue on convergence since 2 years, what we
are missing is add-path with the number of route and ORR.
Best

Hello!
I wonder if this would fit for BIRD router box, with some room for future
growth in the DFZ.
- CPU: Xeon gold 3,2GHz 8cores/16threads
- RAM: 32 or 64gb
How would BIRD behave with such HW specs ? is it overkill ?
The memory is probably overkill for RR in single-table setup, you'll fit in 4G
with a large margin.
CPU is OK. With no or minimal filters, also the convergence time isn't going to
be more than several minutes on this scale.
With the multithreaded version (now 3.0-alpha0), you're gonna get convergence
times in tens of seconds, probably.

Thanks for the feedback ! that's helpful.
I'll try to get one machine to make my test on then.
I assume also that 3.0-alpha is not suitable for production yet :) but I'll try
both anyway.
Thanks and best regards!
