The following configuration shows that the VLAN-bundled logical interface is the interface
over which VPN traffic travels to the CE router and handles traffic for a CCC to which the
VPN connects.

NOTE: Because the VLAN-bundled logical interface supports single-tag
frames, Ethernet is the Layer 2 protocol used to encapsulate incoming traffic.
Although the connection spans multiple VLANs, the VLANs are bundled and
therefore can be encapsulated as a single VLAN.
However, with Ethernet encapsulation, the circuit signal processing does not
check that the VLAN ID list is the same at both ends of the CCC connection.

The following configuration shows that the single-tag logical interface ge-1/0/5.0 bundles
a list of VLAN IDs, and the logical interface ge-1/1/1.0 supports IPv4 traffic using IP address
10.30.1.1/30 and can participate in an MPLS path.
