QinQ on the QFX5100 is driving me fucking insane.

Alright kids, old uncle scream and stomp is trying to configure QinQ on two QFX5110's. For the life of me, and for all the "wisdom" of the Juniper documentation, it won't allow me to configure.

Problems: 1st solution!! (see config below) throws a commit error:

[edit interfaces ge-0/0/12]

unit 300

interface needs to be in a bridge-domain or evpn to support

family bridge

error: configuration check-out failed

Config:

set interfaces ge-0/0/12 flexible-vlan-tagging

set interfaces ge-0/0/12 native-vlan-id 300

set interfaces ge-0/0/12 mtu 9192

set interfaces ge-0/0/12 encapsulation extended-vlan-bridge

set interfaces ge-0/0/12 unit 300 vlan-id-list 1-4094

set interfaces ge-0/0/12 unit 300 input-vlan-map push

set interfaces ge-0/0/12 unit 300 output-vlan-map pop

2nd solution!! No dot1qtunneling option for vlans Config:

set vlans v300 dot1q-tunneling

set vlans v300 layer2-protocol-tunneling all

How in the fuck are you supposed to do this?
