How Do You Configure Q-in-Q on Junos?

To configure Q-in-Q on Junos, first you need to create and configure all necessary customer Virtual Local Area Networks (VLANs) on the neighboring switches. Then, you need to map your customer VLANs (C-VLANs) to the service provider VLANs (S-VLANs). You can do this by using all-in-one bundling to map all packets from all C-VLAN interfaces to an S-VLAN, by using many-to-many bundling to map a subset of the C-VLANs to a subset of the S-VLANs, or by using a specific interface mapping to assign an S-VLAN to an C-VLAN interface.

To use all-in-one bundling, you need to configure the S-VLAN and its interface. Then, you need to configure all-in-one bundling on the C-VLAN.

To use many-to-many bundling, you need to configure all S-VLANs and assign each to an interface. Then, you need to configure many-to-many bundling on every C-VLAN.

To map a specific interface, configure the S-VLAN and its interface. Then, configure a specific interface mapping on the C-VLAN. You can also optionally translate the VLAN ID on the interface.
