Routing

Hi All

I have a problem about L2circuit with QinQ.

I will connect from one switch of A to another switch of B via L2circuit with QinQ

After referred to this website's example.  Still it always is shown no outgoing label.

Neighbor: 103.198.146.2
       Interface                            Type  St     Time last up # Up t  rans
       ge-4/1/9.1012(vc 10012)   rmt    OL

As follow is my structure diagram.

And as attachment is my configuration. Can anyone give me some suggesstion how to modify it?

Thanks

1) check if 173.198.146.2 and 172.54.131.10 present in inet.3 table
2) check if session between these two MXs in operational state in "show ldp session"

if session in 2nd option not present check your firewall on lo0.0 interface if traffic tcp port 646 is allowed for 173.198.146.2 and 172.54.131.10 .

Hi 

Many thanks for reminder.

Yes, ldp session is not connecting ready . After modifed my firewall filter, it's up

Router A> show ldp session
Address State Connection Hold time Adv. Mode
173.198.146.2 Connecting Opening 0 DU

For QinQ, did I set up correctly ? I mean if customer have switches at two side for connecting to my routerA/B 

Can use vlan-id 1012 for outer vlan ?

Best regards,

Yes, this configuration should work fine for QinQ

Did you configure loopback 0 under LDP?

Hi Kingsman

Yes, my lo have joined into OSPF and LDP.

Now L2circuit connection is up as follow.

Neighbor: 173.198.146.2
Interface Type St Time last up # Up trans
ge-4/1/9.1012(vc 10012) rmt Up Jun 27 12:31:14 2018 1
Remote PE: 173.198.146.2, Negotiated control-word: Yes (Null)
Incoming label: 302176, Outgoing label: 302464
Negotiated PW status TLV: Yes
local PW status code: 0x00000000, Neighbor PW status code: 0x00000000
Local interface: ge-4/1/9.1012, Status: Up, Encapsulation: ETHERNET
Flow Label Transmit: No, Flow Label Receive: No

But i just confuse how to make sure QinQ working and verify it.

I hope to set vlan 1012 for cross MPLS backbone. Then will be swapped to origin vlans.

from your current configuration, you the poping the vlan on incoming traffic and sending it out over l2circuit and pushing it again while sending it put to remote CE.

root@mx480# run show interfaces ge-4/1/1.1012 extensive
Logical interface ge-4/1/1.1012 (Index 370) (SNMP ifIndex 535) (Generation 179)
Flags: Up SNMP-Traps 0x4000 VLAN-Tag [ 0x8100.1012 ] In(pop) Out(push 0x8100.1012) Encapsulation: VLAN-CCC
Traffic statistics:
Input bytes : 0

if this is what you want then you are good. 

Hi All

BTW, how to set up the port of switch connectiing to my router ?

If customer's vlan id is 1234, my router will pop 1234 and push 1012 for cross L2vpn, right ?

thanks for your reply

Hi,

Please refer to the below document
