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@JR-2> 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@JR-2> 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@JR-2> show configuration interfaces vlan | display set set interfaces vlan unit 303 family inet address 172.16.101.1/29 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@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@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@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 ?
