Re: 2:2 translation from c-vlan to s-vlan and vice versa - EX Swtich !!!

Or try to use explicit manipulation for vlan-tags with input-vlan-map and output-vlan-map:

interface ge-0/0/1
flexible-vlan-tagging
encapsulation flexible-ethernet-services
unit 1020
encapsulation vlan-bridge
vlan-tags outer 10 inner 20
	input-vlan-map
		swap-swap
		vlan-id 100
		inner-vlan-id 200
	output-vlan-map
		swap-swap

unit 1021
encapsulation vlan-bridge
vlan-tags outer 10 inner 21
	input-vlan-map
		swap-swap
		vlan-id 100
		inner-vlan-id 200
	output-vlan-map
		swap-swap

unit 1130
encapsulation vlan-bridge
vlan-tags outer 11 inner 30
	input-vlan-map
		swap-swap
		vlan-id 100
		inner-vlan-id 200
	output-vlan-map
		swap-swap

unit 1130
encapsulation vlan-bridge
vlan-tags outer 11 inner 31
	input-vlan-map
		swap-swap
		vlan-id 100
		inner-vlan-id 200
	output-vlan-map
		swap-swap

interface ge-0/0/2
flexible-vlan-tagging
encapsulation flexible-ethernet-services
unit 100200
encapsulation vlan-bridge
vlan-tags outer 100 inner 200
