如果MX480和交换机汇聚端口相连使用如下模板

set interfaces xe-1/2/0 vlan-taggingset interfaces xe-1/2/0 encapsulation flexible-ethernet-services

.

set interfaces xe-1/2/0 vlan-tagging

set interfaces xe-1/2/0 encapsulation flexible-ethernet-services

set interfaces xe-1/2/0 unit 200 encapsulation vlan-bridge

set interfaces xe-1/2/0 unit 200 vlan-id 200

set interfaces xe-1/3/0 vlan-tagging

set interfaces xe-1/3/0 encapsulation flexible-ethernet-services

set interfaces xe-1/3/0 unit 200 encapsulation vlan-bridge

set interfaces xe-1/3/0 unit 200 vlan-id 200

set interfaces irb unit 0 family inet address 10.66.1.33/30

set bridge-domains vlan200 domain-type bridge

set bridge-domains vlan200 interface xe-1/2/0.200

set bridge-domains vlan200 interface xe-1/3/0.200
