  • Flexible Ethernet support (QFX10002, QFX10008, and QFX10016)—Starting in Junos OS Release 21.2R1, you can configure flexible Ethernet services to support a Layer 2 bridging interface while simultaneously supporting other encapsulation options on the same physical interface. You can configure a physical or aggregate Ethernet interface to simultaneously support Layer 2 bridging, Layer 3 IP routing, and VLAN-based CCC connections.


    On QFX10000 line of Switches running Junos OS releases earlier than Release 21.2R1, we do not support configuring vlan-bridge and any other encapsulations on an interface that has flexible-ethernet-services enabled.
