İlk önce aşağıdaki komutla apt reposunu güncelleyin.
apt update
Ardından “bridge-utils” paketini sisteme kurun.
apt install bridge-utils
Daha sonra “/etc/network/interfaces” dosyasını aşağıdaki gibi yapılandırabilirsiniz. Tabi siz kullanacağınız şekilde yapılandırabilirsiniz. Ben aşağıdaki örnekte hem bonding, hem b, hem bridge vlan, hem bridge vxlan, hem de mtu size olarak jumbo frame **kullandım. Ayrıca **nfs ve iscsi yide ayrı vlan‘larla yapılandırdım. Siz ortamınızda gerekli olan yapılandırmaya göre şekillendirebilirsiniz.
