What value in the address field of frame relay header identifies the destination of the frame?
DLCI
What value in the address field of a Frame Relay header identifies the destination of the frame?
DLCI
Which two features are identified with Frame Relay connections?
Dlci pvc
When configuring a Frame Relay connection what is the purpose of Inverse ARP?
to create a mapping of DLCI to Layer 3 addresses that belong to remote peers
Why would you want to map an ip address to a dlci?
When the router wants to send traffic to an IP address across a Frame Relay link, it needs to tell the frame switch which PVC the traffic should traverse. A frame switch drops any traffic it receives that has no DLCI in the header, because it has no way of determining how to route the data.
What is frame relay in IEEE 802.11?
Frame Relay is a WAN (Wide Area Network) encapsulation protocol. It is considered a Multi-Access-Non-Broadcast medium. Each router has a DLCI number that will uniquely identify a specific route, however that DLCI is locally significant only. Data from your router will be sent into the Frame-Relay cloud, there the frames are switched (OSI layer 2). The path traveled is only there when it is needed. Your Service Provider might be switching towards MPLS though.
What is created between two DTEs in a frame relay network?
Virtual Circuit is Created. Each circuit is known by its DLCI. i.e. Data Link Connection Identifier.
What is the full form of dlc?
To set the source Data-Link Connection Identifier (DLCI) for use when the Local Management Interface (LMI) is not supported, use the frame-relay local-dlci command in interface configuration mode. To remove the DLCI number, use the noform of this command.

What can X25 do the Frame Relay cannot do?
There are various differences between X.25 and Frame Relay. The most significant are: 1. Call Control X.25 connection establishment and release (call control) use in-band signaling within the same virtual channel used for user data transmission causing additional overhead. Frame Relay call control uses separate virtual channels identified by reserved DLCI using the LMI (Local Management Interface) protocol. 2. Routing vs. Switching X.25 performs packet switching on OSI layer 3 (network layer); Frame Relay performs packet switching on OSI layer 2 (data-link). Frame Relay does not use any layer 3 protocol. 3. Flow Control Frame Relay (FR) doesn't perform flow control between frame handlers (FR routers). X.25 routers have to acknowledge each frame; in case of frame errors frames have to be retransmitted and acknowledged. Frame Relay relies on flow control performed by higher layer protocols.Source: http://www.synapse.de/ban/HTML/P_LAYER2/Eng/P_lay264.html
What frame-relay command shows encapsulation type?
show frame-relay map
How does frame relay work?
Frame Relay is a packet-switching technology. It works by sending information in packets, which are called frames, through a shared frame-relay network.
