HI,


We have a network, simplified in the below diagram.

Our need is to have a QinQ transport on the red line, from a subinterface on NE40, PEVID 2000 trunked out on another subinterface, and terminated on a switch.


QinQ

Switch configuration is OK, using standard dot1Q and QinQ terminated interface


On the NE40 we have configuration similar to this:


Customer terminating interface on NE40:

        interface gigabitinterface 0/3/1

        #

        interface gigabitinterface0/3/1.2000

        description "Customer connection location A"

        encapsulation qinq-termination

        qinq termination l2 symmetry

        qinq termination pe-vid 2000 ce-vid any

        #

 Core interface on NE40:

        interface gigabitinterface 0/3/2

        #

        interface gigabitinterface 0/3/2.2000

        description "core link to switch S6730"

        vlan-type dot1q 2000

        #

 The two subinterface on NE40 are connected using CCC:

        ccc TEST interface gigabitinterface0/3/1.2000 out-interface gigabitinterface0/3/2.2000



Switch configuration:
vlan 2000

interface XGigabitEthernet0/0/1
description "core link towards NE40"
portswitch
 port link-type trunk
 port trunk allow-pass vlan 2000
 
interface XGigabitEthernet0/0/2
description "Customer connection location B"
portswitch
 port link-type dot1q-tunnel
 port default vlan 2000


My problem is the configuration on NE40. Anyone got something similar up and running?

The switch port has to be in trunk mode. Not in access mode. Because the outer VLAN has to be delivered with a tag to the router.

Switchport is QinQ, should be OK

interface XGigabitEthernet0/0/2
description "Customer connection location B"
portswitch
port link-type dot1q-tunnel
port default vlan 2000
