MPLS L2VPN Business traffic is blocked

CE1 —— PE1 —— PE2 —— CE2

Because CE has multiple service VLANs, the customer does not want all service VLANs to be created on PE. The customer configures qinq on the AC port but it does not take effect.

1. After acknowledging, the device does not support the deployment method of MPLS L2VPN + QinQ.

2.  According to customer needs, it can be achieved by matching s-vid 1-4094. However, this requires that the traffic coming from CE carries the VLAN tag.

3.  In addition, need to use s-vid to match all vlans to allow traffic from all CEs, xconnect-group needs to use Ethernet mode. The specific configuration is as follows:

service-instance 200
  encapsulation s-vid 1 to 4094
#
#
xconnect-group Test
connection ldp
  ac interface GigabitEthernet1/0/11 service-instance 200 access-mode ethernet
  peer 172.xx.xx.2 pw-id 200
#  

Use s-vid to match all vlans to allow traffic from all CEs, and xconnect-group needs to use Ethernet mode.
