The upper limits for configurable VLAN IDs vary by interface type.
When you configure a TCC encapsulation, some modifications are needed to handle
VPN connections over unlike Layer 2 and Layer 2.5 links and terminate the Layer 2 and
Layer 2.5 protocol locally.
The router performs the following media-specific change:
ATM—Operation, Administration, and Maintenance (OAM) and Interim Local
Management Interface (ILMI) processing is terminated at the router. Cell relay is not
supported. The Junos OS strips all ATM encapsulation data from incoming frames
before forwarding them. For output, the next hop is changed to ATM encapsulation.

Configure PPP encapsulation on a SONET/SDH interface. The second and third
statements allow Intermediate System-to-Intermediate System (IS-IS) and MPLS to
run on the interface.
