Configure double VLAN tags (802.1ad) on Linux machine
by beziabdelkarim from LinuxQuestions.org on (#4VAJQ)
Hello,
I'm trying to configure a linux machine as a bridge between 2 different networks.
The machine has 2 real network interfaces eth0 and eth1.
The first network interface (eth0.10) receives packets tagged using VLAN ID 10
After routing, I need to add an extra VLAN header (802.1ad) for outgoing packets from second network interface. (VLAN id 30) ==> eth1.30
So outgoing traffic will have S-tag added i.e. : 2x VLAN headers (VLAN 10 and VLAN 30)
Is it any easy way / example to follow in order to make this setup?
Linux networking configuration commands would be helpful
Thanks in advance
