May 20, 2026BBRv3 Support
Hello, Community!
According to
https://my.f5.com/manage/s/article/K50411377 BBR is supported on F5 boxes since TMOS 14.1.0
According to
https://github.com/google/bbr BBR version 3 should be used currently
Does someone know which BBR version F5 devices use?

Hi Vladimir_Akhmarov ,
The short answer is TMOS currently uses BBRv1 since this is based off Linux Kernel TCP stack. TMOS BBR implementation does not cover ECN/Loss rates which are part of the BBR v2/v3 descriptions. However BIG-IP CNF does support BBrv2 article here CNF BBRv2.
