示例：堆叠和重写千兆以太网 IQ VLAN 标记
配置 VLAN CCC 隧道，其中以太网帧在接口处进入隧道，在接口ge-4/0/0ge-4/2/0处退出隧道。
以下示例演示如何执行以下任务：
在入口处推送 TPID 和 VLAN ID 对
[edit interfaces]
ge-4/0/0 {
vlan-tagging;
encapsulation vlan-ccc;
gigether-options {
ethernet-switch-profile {
tag-protocol-id 0x9909;
}
}
unit 0 {
encapsulation vlan-ccc;
vlan-id 512;
input-vlan-map {
push;
tag-protocol-id 0x9909;
vlan-id 520;
}
output-vlan-map pop;
}
}
ge-4/2/0 {
vlan-tagging;
encapsulation vlan-ccc;
unit 0 {
encapsulation vlan-ccc;
vlan-id 515;
input-vlan-map {
swap-push;
vlan-id 520;
inner-vlan-id 512;
}
output-vlan-map {
pop-swap;
}
}

堆栈内部和外部 VLAN 标记
