What do you mean by frame relay?
Frame relay is a protocol that defines how frames are routed through a fast-packet network based on the address field in the frame. Frame relay takes advantage of the reliability of data communications networks to minimize the error checking done by the network nodes.
What does relay in frame relay switching describe?
Frame relay is a packet-switching telecommunications service designed for cost-efficient data transmission for intermittent traffic between local area networks (LANs) and between endpoints in wide area networks (WANs). This approach speeds up data transmission.
What is frame relay discuss its various types?
Frame Relay is that the transmission mode during which information is transferred through electric circuit layer, within the style of packets….Asynchronous Transmission Mode (ATM):
| S.NO | Frame Relay | ATM |
|---|---|---|
| 6. | The throughput of frame relay is moderate. | While it’s throughput is high. |
What is Frame Relay point?
On Frame Relay networks, a single VC is always provisioned for a point-to-point connection. The same VC originates at a local end and then terminates at the remote end. A subnet address is usually assigned to each point-to-point connection. Therefore, only one DLCI can be configured per point-to-point subinterface.
What is Frame Relay discuss how frame relay operates?
Frame Relay sends information in packets called frames through a shared Frame Relay network. Each frame contains all the information necessary to route it to the correct destination. So in effect, each endpoint can communicate with many destinations over one access link to the network.
Why do we use frame relays?
Frame Relay often serves to connect local area networks (LANs) with major backbones, as well as on public wide-area networks (WANs) and also in private network environments with leased lines over T-1 lines. It requires a dedicated connection during the transmission period.
What is Frame Relay discuss how Frame Relay operates?
What are the basic characteristics of Frame Relay?
Some important features of frame relay are :
- Frame relay operates at a high speed (1.544 Mbps to 44.376 Mbps).
- Frame relay operates only in the physical and data link layers.
- It allows the bursty data.
- It has a large frame size of 9000 bytes.
- Frame relay can only detect errors (at the data link layer).
Are there any specific commands for Frame Relay?
This is not related to frame-relay directly but it is required for serial interfaces and easily overlooked. Now we can configure some frame-relay specific commands: There are three frame-relay specific commands that we configured:
Which is the default encapsulation for Frame Relay?
interface serial 0/0/0 :- This command is used to enter in interface mode. In Cisco routers default encapsulation is set to HDLC. We cannot use Frame Relay with default encapsulation. Next command changes this encapsulation.
Do you need a Cisco frame relay switch?
If you are studying frame-relay for (Cisco) exams then you only need to understand how to configure it from the customer’s perspective. If you want to configure frame-relay in your lab then you do require a frame-relay switch. Luckily for us, it’s possible to configure a Cisco router as a frame-relay switch.
What is a multipoint interface in Frame Relay?
Multipoint interfaces are logical Frame Relay sub-interfaces but they can terminate more than one PVCs just like physical serial interfaces. R1 has a multipoint Frame Relay sub-interface connected to subnet 192.168.123.0/24 while a point-to-point subinterface terminates the PVC to R4.
