Frame Relay allows us to connect multiple VCs with single physical access link. hardeep says. Frame relay is a WAN technology. Tags: cisco, frame relay. The former is often used to connect two Cisco routers while the latter is used to connect a Cisco router to a non-Cisco router. Frame-relay uses data-link connection identifiers (DLCIs) to build up logical circuits. The switches are interconnected in a complex mesh topology. Frame Relay, le remplaçant de X.25, demande moins de temps de traitement que X.25 car il ne fournit pas de corrections d’erreurs. This set of Data communication and Networking Multiple Choice Questions and Answers (MCQs) focuses on “Frame Relay ”. It operates at the data link layer providing a connection-oriented network. Frame-relay requires a frame-relay switch that “switches” one DLCI to another, creating a virtual circuit. The Frame relay originally designed for transport across Integrated Services Digital Network (ISDN) infrastructure, it may be used today in the context of many other network interfaces. A Frame Relay network is made up of a large number of Frame Relay switches dispersed all over the coverage area of a Frame Relay service provider. We can use Fiber Optics, Frame Relay lines, ADSL, SDSL and Ípsilon, contracted Andorra Telecom and Wi-Fi connections, even in a single network utiltizar several types of lines at the same time. This tutorial explains how to configure Frame Relay step by step. Frame relay switching table consists of four fields viz. Frame Relay – WAN Connection. Read the ...

You can test with your Cisco router when typing the command Router(config-if)# The encapsulation frame-relay command is mandatory on the main serial interface before configuring frame-relay sub interfaces. IN_port, IN_DLCI, OUT_port and OUT_DLCI. Frame Relay DLCIs have local significance, which means that the values themselves are not unique in the Frame Relay WAN. The figure-6 depicts Operation of FRAD (Frame Relay Assembler and Disassembler). Inverse-ARP is enabled by default on Cisco routers. Here we are going to show you, how to configure Frame relay in Cisco routers using Cisco Packet Tracker. Cisco supports two Frame Relay encapsulation types: the Cisco encapsulation and the IETF Frame Relay encapsulation, which is in conformance with RFC 1490 and RFC 2427. Haaaaaa! Frame-relay provides the dedicated connection called the PVC which is used to form logical end-to-end links mapped over a physical network. Normally you don’t really have to think about the frame-relay switch since this is something that the service provider will configure. Frame Relay DLCI (data link connection identifiers) explained. The following figure to shows how to make the frame-relay connections. It is a specialized device which is designed to provide connection between LAN and Frame Relay WAN (Wide Area Network). Pour celà on va devoir lui indiquer son rôle de switch frame-relay, mais également définir les routes frame-relay. ATM et Frame Relay, par exemple, sont deux exemples de protocoles orientés connexion non fiable. Once you have created the frame-relay connections, close the Cloud0 properties dialog box. Bursty, high speed Frame Relay connections, can access the entire network trunk bandwidth for very short intervals, and then release it for other applications. The identifiers have local meaning only, that means that their values are unique per router, but not necessarily in the other routers. In first example of this tutorial, we connected six VCs with single physical link ( serial interface). Au sein du nuage Frame Relay, la connexion entre deux sites se fait par l'intermédiaire de circuits virtuels qui peuvent être établis en dur par le fournisseur, dans ce cas, ils sont permanents et on parle de Permanent Virtual Circuit (PVC). It is the customer equipment that terminates the Frame Relay connection. Features of Frame relay: This feature is not available right now. Frame Relay virtual circuits are identified by data-link connection identifiers (DLCIs). I have a 1720 router with 2 56k csudsu wic cards and have a 2507 router with 16 port hub, I need to know if I can setup frame relay from the 56k wic cards to my 2507 router and if possible the steps needed to make it work.
