What are the differences between Routed RFC 1483 PVCs and Bridged RFC 1483 PVCs?

A. In most cases, the differences refer to the LLC Encapsulation SubNetwork Attachment Point (SNAP) PVCs. Routed PVCs have only the 802.2 LLC header (0xFE-FE-03), which the 802.1a SNAP field can possibly follow. Bridged PVCs have the 802.1 header (0xAA-AA-03) and several other fields that include a metropolitan-area network destination address. Refer to Multiple Routed Protocols Over ATM PVCs Using LLC Encapsulation for an example of an RFC 1483 routed configuration. Refer to Basic PVC Configuration Using Bridged RFC 1483 for a Bridged RFC 1483 configuration.
