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: 18.104.22.168 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?
1) check if 22.214.171.124 and 126.96.36.199 present in inet.3 table2) 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 188.8.131.52 and 184.108.40.206 .
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. Mode220.127.116.11 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 ?
Yes, this configuration should work fine for QinQ
Did you configure loopback 0 under LDP?
Yes, my lo have joined into OSPF and LDP.
Now L2circuit connection is up as follow.
Neighbor: 18.104.22.168 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: 22.214.171.124, 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.
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
