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
encapsulationstatement at the[edit interfacesso-fpc/pic/port] hierarchy level and selectframe-relay-cccas the encapsulation type. To enable Frame Relay CCC at the logical interface level, include theencapsulation frame-relay-cccstatement at the [edit interfacesso-fpc/pic/portunitunit-number] hierarchy level.To configure Cisco HDLC CCC interface encapsulation, include the
encapsulationstatement at the[edit interfaces so-fpc/pic/port]hierarchy level and selectcisco-hdlc-cccas the encapsulation type.To configure PPP CCC interface encapsulation, include the
encapsulationstatement at the[edit interfacesso-fpc/pic/port] hierarchy level and selectppp-cccas the encapsulation type.[edit] interfaces { so-0/0/0 { encapsulation (frame-relay-ccc | cisco-hdlc-ccc | ppp-ccc); unit 0 { encapsulation frame-relay-ccc; } } }
