Configuring Layer 2 Circuits

When you configure Layer 2 circuits, you can use Ethernet, SONET/SDH, and ATM2 IQ interfaces on a PE router. The specific steps you must take to configure these interface types for Layer 2 circuits are described as follows:

• Configuring CCC Encapsulation on CE-Facing Ethernet Interfaces
• Configuring CCC Encapsulation on CE-Facing SONET/SDH Interfaces
• Configuring a CCC Encapsulation and a Layer 2 Circuit Mode on CE-Facing ATM2 IQ Interfaces
• Configuring the MPLS Family on Core Interfaces
• Configuring the Layer 2 Circuit Neighbor Address and Virtual Circuit Identifier
• Configuring LDP and an IGP to Transport Layer 2 Circuits
• Option: Applying Traffic Engineering to a Layer 2 Circuit
• Option: Mapping Layer 2 Protocol Control Information into a Layer 2 Circuit
• Option: Configuring APS for Layer 2 Circuits
• Option: Configuring Layer 2 Circuit Trunk Mode on ATM2 IQ Interfaces
• Option: Reserving LSP Bandwidth for a Layer 2 Circuit
• Option: Selecting an MTU for a Layer 2 Circuit
• Option: Configuring Local Interface Switching for a Layer 2 Circuit
• Option: Configuring Layer 2 Circuits Simultaneously over RSVP and LDP LSPs
