1. Frame Relay Parsing

1. It belongs to the connected two-layer network technology

DLCI (Data Link Connection Identification) identifies PVC between router and Frame Relay switch, valid locally

PVC (permanent virtual circuit)

LMI (Local Management Interface) A signaling standard between routers and frame relay switches that manages connections between devices and maintains their connection status.

5. MAP IP and DLCI mapping table

PVC (LMI) status

PVC (LMI) status Local to peer Active Normal Inactive Normal Abnormal

Delete Abnormal Unknown
