How do I configure my router as a Frame Relay switch?
Enable Frame Relay switching on the router using the command frame-relay switching in the global configuration mode. Go to the interface configuration mode of the Frame Relay interface where you want to configure Frame Relay switching.
What is a Frame Relay switch?
Frame Relay switches create virtual circuits to connect remote LANs to a WAN. The Frame Relay network exists between a LAN border device, usually a router, and the carrier switch.
What is the purpose of a Frame Relay switch?
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).
What is Frame Relay encapsulation?
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. Each data link layer needs such a field to define the type of Layer 3 packet carried by the data link frame.
How do I enable Frame Relay?
The configuration is pretty simple here and we are just enabling Frame Relay encapsulation using the encapsulation frame-relay command.
- R1> enable. R1# configure terminal.
- R2> enable. R2# configure terminal.
- R3> enable. R3# configure terminal.
- R1#show frame-relay map.
- R1#show frame-relay lmi.
- R1#debug frame-relay lmi.
What is the command to make a router as a relay?
To rectify this, we can configure R1 to act as a DHCP relay agent and forward the request to the configured DHCP server. This is done by issuing the ip helper-address DHCP_SERVER_IP_ADDRESS command on its Gi0/0 interface. This command instructs the router to do the following: watch for DHCP messages on the interface.
Which network is cheaper than Frame Relay?
Explanation: Frame Relays uses carriers such as SONET (for fiber-optic connections) to physically transmit data frames over a Frame Relay network. SONET is cheaper and provides better network reliability than other carriers.
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.
How do you check a Frame Relay?
1. Use the show interfaces serial command to check the state of the interface. 2. If the output shows that the interface is up but the line protocol is down, use the show frame-relay lmi exec command to see which LMI type is configured on the Frame Relay interface.
What is Relay ip address?
A DHCP relay agent is a host or router that forwards DHCP packets between clients and servers. It allows local hosts to acquire dynamic IP addresses from the remote DHCP Server. Relay agent receives DHCP messages and generates a new DHCP message to send out on another interface.
What is Relay Agent?
DHCP relay agent is any TCP/IP host which is used to forward request and replies between DHCP server and client when the server is present on the different network. Relay agents receive DHCP messages and then generate a new DHCP message to send out on another INTERFACE.
How to configure Frame Relay For Your Network?

How to change default encapsulation method to Frame Relay?
Next command is used to change default encapsulation method to Frame Relay. Fifth command is used to enable the interface. These five commands are explained in previous example. Okay Let’s understand remaining commands. As we can see in figure R1 is connected with three sites from single serial interface.
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.
When to use IETF form of Frame Relay?
Use the IETF form of Frame Relay encapsulation if your device or access server is connected to another vendor’s equipment across a Frame Relay network. IETF encapsulation is supported either at the interface level or on a per-VC basis. Shut down the interface prior to changing encapsulation types.
