What is DTE and DCE in Frame Relay?

A Frame Relay network provides data communications between user devices such as routers and hosts. The user devices are also called data terminal equipment (DTE). The devices that provide access to the Frame Relay network for DTEs are called data circuit-terminating equipment (DCE).

What is Frame Relay in Cisco?

In frame relay, the routers connected to remote networks are usually the DTE devices while the frame relay switch is usually the DCE device. The frame relay switches move data frames from the host networks across the WAN network to the remote DTE devices.

What is encapsulation Frame Relay?

Frame Relay is a data link protocol and the customer router encapsulates each Layer 3 packet inside a Frame Relay frame comprising a header and trailer before it is sent out the access link.

What is Frame Relay configuration?

Frame Relay is a Layer 2 WAN protocol that cand be configured on physical serial links. In addition to physical interfaces, you can also configure two types of logical interfaces for Frame Relay – point-to-point and multipoint.

What is the traffic shaping over Frame Relay feature?

The traffic shaping over Frame Relay feature applies to Frame Relay permanent virtual circuits (PVCs) and switched virtual circuits (SVCs).

How do I perform a Cisco frame relay switch?

You perform switching by configuring your Cisco router or access server into a Frame Relay network. There are two parts to a Frame Relay network: Frame Relay data terminal equipment (DTE) – the router or access server. Frame Relay data circuit-terminating equipment (DCE) switch.

What is Frame Relay?

Industry-standard, switched data link layer protocol that handles multiple virtual circuits using HDLC encapsulation between connected devices. Frame Relay is more efficient than X.25, the protocol for which it generally is considered a replacement. Recently viewed documents for this product will appear here.

How do I back up Frame Relay circuits using ISDN?

You may want to back up Frame Relay circuits using ISDN. There are several ways to do this. The first, and probably the best, is to use floating static routes that route traffic to a Basic Rate Interface (BRI) IP address and use an appropriate routing metric.
