Hi All,

I just did the lab about QinQ which will be applied on our network. below
is the connectivity:

JR-2 (trunk) ----------------(access)EX3200(access)-----------(trunk)JR-3

I've done the following configuration:

*on EX3200*
set vlans VLAN607 vlan-id 607
set vlans VLAN607 dot1q-tunneling customer-vlans 300-310
set vlans VLAN608 vlan-id 608
set vlans VLAN608 dot1q-tunneling customer-vlans 311

set interfaces ge-0/0/7 description JR-3
set interfaces ge-0/0/7 unit 0 family ethernet-switching port-mode *access*
set interfaces ge-0/0/7 unit 0 family ethernet-switching vlan members
VLAN607
set interfaces ge-0/0/7 unit 0 family ethernet-switching vlan members
VLAN608

set interfaces ge-0/0/6 description JR-2
set interfaces ge-0/0/6 unit 0 family ethernet-switching port-mode *access*
set interfaces ge-0/0/6 unit 0 family ethernet-switching vlan members
VLAN607
set interfaces ge-0/0/6 unit 0 family ethernet-switching vlan members
VLAN608

*on JR-2*
samol at JR-2> show configuration vlans | display set

set vlans VLAN303 l3-interface vlan.303
set vlans VLAN304 vlan-id 304
set vlans VLAN304 l3-interface vlan.304
set vlans VLAN311 vlan-id 311
set vlans VLAN311 l3-interface vlan.311

VLAN304
set interfaces fe-0/0/0 unit 0 family ethernet-switching vlan members
VLAN311

set interfaces vlan unit 304 family inet address 172.16.102.1/29
set interfaces vlan unit 311 family inet address 172.16.111.1/29

*on JR-3*
samol at JR-3> show configuration vlans | display set
set vlans VLAN303 vlan-id 303
set vlans VLAN303 l3-interface vlan.303
set vlans VLAN304 vlan-id 304
set vlans VLAN304 l3-interface vlan.304
set vlans VLAN311 vlan-id 311
set vlans VLAN311 l3-interface vlan.311

samol at JR-3> show configuration interfaces fe-0/0/0 | display set
set interfaces fe-0/0/0 unit 0 family ethernet-switching port-mode *trunk*
set interfaces fe-0/0/0 unit 0 family ethernet-switching vlan members
VLAN303
set interfaces fe-0/0/0 unit 0 family ethernet-switching vlan members
VLAN304
set interfaces fe-0/0/0 unit 0 family ethernet-switching vlan members
VLAN311

samol at JR-3> show configuration interfaces vlan | display set
set interfaces vlan unit 303 family inet address 172.16.101.6/29
set interfaces vlan unit 304 family inet address 172.16.102.6/29
set interfaces vlan unit 311 family inet address 172.16.111.6/29

Based on my configuration above, I can describe the result as below:


   1. Frames traffic from JR-2 will be tagged with OUTER VLAN 607 for those
   coming with VLAN 303 and 304
   2. Frames traffic from JR-2 will be tagged with OUTER VLAN 608 for those
   coming with VLAN 311
   3. Frames with the outer vlan tagged will go out to JR-3 by POP'ing OFF
   the OUTER VLAN send out frames with INNER vlan tagged.

I've applied the configuration in the lab and it's working. VLAN 311 won't
be able to ping between JR-2 and JR-3 without use of VLAN 608 as outer vlan
( VLAN 607 does not include VLAN 311 in the range).

So, based on what i did here, I can say EX3200 does support the POP off
outer vlan ?

Regards.
