Configuring CCC Encapsulation on CE-Facing SONET/SDH Interfaces

On SONET/SDH interfaces in a PE router, you can use Frame Relay CCC, Cisco HDLC CCC, or PPP CCC encapsulation for Layer 2 circuits:

To configure Frame Relay CCC interface encapsulation, include the encapsulation statement at the [edit interfaces so-fpc/pic/port] hierarchy level and select frame-relay-ccc as the encapsulation type. To enable Frame Relay CCC at the logical interface level, include the encapsulation frame-relay-ccc statement at the [edit interfaces so-fpc/pic/port unit unit-number] hierarchy level.
To configure Cisco HDLC CCC interface encapsulation, include the encapsulation statement at the [edit interfaces so-fpc/pic/port] hierarchy level and select cisco-hdlc-ccc as the encapsulation type.
To configure PPP CCC interface encapsulation, include the encapsulation statement at the [edit interfaces so-fpc/pic/port] hierarchy level and select ppp-ccc as the encapsulation type. [edit] interfaces { so-0/0/0 { encapsulation (frame-relay-ccc | cisco-hdlc-ccc | ppp-ccc); unit 0 { encapsulation frame-relay-ccc; } } }
