<p>What is the best way to enable BBR on default for my clusters?
In this <a href="https://cloud.google.com/kubernetes-engine/docs/how-to/node-system-config" rel="nofollow noreferrer">link</a>, I didn't see an option for controlling the congestion control.</p>

<p>Google BBR can only be enabled in Linux operating systems. By default the Linux servers uses Reno and CUBIC but the latest version kernels also includes the google BBR algorithms and can be enabled manually.</p>
<p>To enable it on CentOS 8 add below lines in /etc/sysctl.conf and issue command sysctl -p</p>
<p>net.core.default_qdisc = fq
net.ipv4.tcp_congestion_control = bbr</p>
<p>For more Linux distributions you can refer to this <a href="https://supporthost.in/how-to-install-google-bbr/" rel="nofollow noreferrer">link</a>.</p>
