Do routers at different ends of a PVC circuit identify that PVC with the same DLCI?

Understanding DLCI in Frame Relay Networks

Yes, routers at different ends of a PVC circuit will identify that PVC with the same DLCI. But what exactly is DLCI?

DLCI (Data Link Connection Identifier) is a number that identifies a specific PVC (Permanent Virtual Circuit) in Frame Relay networks. It serves as a label used by routers to ensure that data is delivered to the correct PVC.

When a PVC is established, both ends of the connection agree on a DLCI value for that specific PVC. This agreed-upon DLCI value is then used by both ends of the connection to identify the PVC and direct data traffic to the intended destination. Therefore, regardless of the physical locations of the routers, they will utilize the same DLCI to reference a particular PVC.

The DLCI acts as a unique identifier that enables routers to differentiate between different PVCs within a Frame Relay network. This ensures accurate communication between routers situated at opposite ends of the circuit.

DLCI (Data Link Connection Identifier) is a number that identifies a specific PVC (Permanent Virtual Circuit) in Frame Relay networks. It is utilized by routers to ensure that data is transmitted to the correct PVC. When a PVC is established, both ends of the connection agree on a DLCI value for that PVC, which is then employed by both ends to recognize the PVC and guarantee that data is directed accurately to its intended destination. The DLCI functions as a unique identifier that allows routers to differentiate between various PVCs in a Frame Relay network, facilitating proper communication between routers positioned at different ends of the circuit.
