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:
IP
MPLS
PPPoE
Transparent bridging
Figure 44 on page 445 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:
S-VLAN oversubscription is not supported on bridged Ethernet interfaces.
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.
For more information, see:
"Configuring VLAN and S-VLAN Subinterfaces" on page 167 for introductory information
about VLANs and S-VLANs.
