after step of deploy Kubernetes with kubeadm, the note is :

There are two work-arounds:
Add net.bridge.bridge-nf-call-ip6tables = 1 and net.bridge.bridge-nf-call-iptables = 1 to /etc/sysctl.conf
Type sysctl -p to apply the settings from /etc/sysctl.conf
""""Type sysctl net.bridge.bridge-nf-call-ip[6]tables to verify the values are set to 1.""""

The command "sysctl net.bridge.bridge-nf-call-ip[6]tables" is for ip and for ip6.

This command change to sysctl net.bridge.bridge-nf-call-iptables and sysctl net.bridge.bridge-nf-call-ip6tables .
