I tried this and we got closer but it is replacing both inner and outer
tags now:
12:48:27.320821 00:22:07:4d:7b:0d > ff:ff:ff:ff:ff:ff, ethertype 802.1Q
(0x8100), length 350: vlan 424, p 0, ethertype 802.1Q, vlan 424, p 0,
ethertype IPv4, 0.0.0.0.68 > 255.255.255.255.67: BOOTP/DHCP, Request
from 00:22:07:4d:7b:0d, length 300
That should have been outer 424 inner 201.
The config:
baldur at formervangen-edge1# show interfaces xe-0/1/7
flexible-vlan-tagging;
native-vlan-id 424;
encapsulation flexible-ethernet-services;
unit 424 {
encapsulation vlan-vpls;
vlan-id 424;
input-vlan-map pop;
output-vlan-map push;
}

mac-statistics;
mesh-group 1 {

neighbor 10.9.124.0;
