Bridged Ethernet interfaces on E-series routers support the configuration of virtual local area networks (VLANs) and stacked virtual local area networks (S-VLANs). A VLAN permits multiplexing multiple higher-level protocols over a single physical port. An S-VLAN provides a two-level VLAN tag structure, which extends the VLAN ID space to more than 16 million VLAN tags.
Specifically, you can statically configure the following higher-level protocols over a VLAN or an S-VLAN subinterface that is stacked above a bridged Ethernet interface:
Figure 37 illustrates the interface stacking supported on E-series routers for VLANs over bridged Ethernet.

VLANs and S-VLANs configured over bridged Ethernet interfaces provide the same basic capabilities as VLANs and S-VLANs configured over Ethernet interfaces, with the following exception:
After you configure the bridged Ethernet interface, you configure the VLANs, S-VLANs, and the supported higher-level protocols in the same way that you configure them over Ethernet interfaces.
