The following figure to shows how to make the frame-relay connections. 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. Frame-relay uses data-link connection identifiers (DLCIs) to build up logical circuits. The DLCI number defines a single virtual connection through the WAN and are the Frame Relay equivalent to a hardware address. RT-FR agira comme switch frame-relay, c’est-à-dire que son rôle sera de relayer ce qui vient de RT1 vers RT2 et inversément. Basically we divided a serial interface in six sub-interfaces and assigned one VC with each sub interface. FRF. The identifiers have local meaning only, that means that their values are unique per router, but not necessarily in the other routers. 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). Frame relay is a packet-switching protocol for connecting devices on a Wide Area Network (WAN). the Frame-Relay switch via LMI, using Inverse-ARP. FRF.11 defines the formats, and FRF.12 subdivides large frames in order to interleave real-time voice with data on slow connections. Frame relay switching table consists of four fields viz. ATM et Frame Relay, par exemple, sont deux exemples de protocoles orientés connexion non fiable. In the previous note, "Why Frame Relay? Haaaaaa! The encapsulation frame-relay command is mandatory on the main serial interface before configuring frame-relay sub interfaces. It operates at the data link layer providing a connection-oriented network.

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. Please try again later. Users have been complaining that their Frame Relay connection to the corporate site is very slow. This article will explain frame relay configuration in Cisco Packet Tracer. Frame Relay allows us to connect multiple VCs with single physical access link. 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. Tags: cisco, frame relay. Overview. The figure-6 depicts Operation of FRAD (Frame Relay Assembler and Disassembler). For example, there is only one DLCI of 23 representing for the connection from HeadQuarter to Branch 1 and only one DLCI of 51 from HeadQuarter to Branch 2. … 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 former is often used to connect two Cisco routers while the latter is used to connect a Cisco router to a non-Cisco router. The network administrator suspects that the link is overloaded. 10. In first example of this tutorial, we connected six VCs with single physical link ( serial interface). Frame Relay Advantages and Disadvantges IN_port, IN_DLCI, OUT_port and OUT_DLCI. 2) DCE (Data Circuit-Terminating Equipment) The DCE device is the network equipment owned by the provider of the leased line. Frame-Relay connection. This tutorial explains how to configure Frame Relay step by step. Le fameux Frame-Relay ! Frame Relay (frame relay) is a packet switching technology that fragmented into transmission units called frames and sent in high-speed bursts through a digital network. Ils peuvent aussi être établis uniquement sur demande et on parle de Switched Virtual Circuit (SVC). Features of Frame relay: 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. ", we had a long journey trying to understand the subtleties of Frame Relay technology as well as its configuration.For any troubleshooting attempt to be successful, you need to have a good understanding of the technology, so you may want to spend some time reading the first note about Frame Relay, if you haven’t done so yet. Frame Relay Virtual Connection . Frame Relay – WAN Connection. Frame-relay provides the dedicated connection called the PVC which is used to form logical end-to-end links mapped over a physical network. Serial 0 B. R1-R3 C. Serial 2 D. R3-R1. It is a specialized device which is designed to provide connection between LAN and Frame Relay WAN (Wide Area Network). Read the ... How to Configure a Cisco router as a Frame Relay Switch Configure Inter-VLAN routing on Cisco Router How to connect GNS3 to the Internet How to Configure PPP in Cisco Routers Answers for CCNP TSHOOT Demo Exam. 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. The data link layer Frame Relay Virtual Connection object is bound by its Containing Termination Points attribute to a data link layer Frame Relay Interface object. encapsulation frame-relay (Inverse-ARP marche encore ici) Spokane interface Serial0 ip address 172.16.1.1 255.255.255.0 encapsulation frame-relay frame-relay map ip 172.16.1.3 102 frame-relay map ip 172.16.1.2 102 Spokomo interface Serial0 ip address 172.16.1.3 255.255.255.0 encapsulation frame-relay frame-relay map ip 172.16.1.1 211 Nous pouvons utiliser les lignes Fibre Optique, Frame Relay , ADSL, SDSL et Ípsilon, contracté a Andorra Telecom, et Wi-Fi, même dans un seul réseau de différents types de lignes en même temps. It is the customer equipment that terminates the Frame Relay connection. Frame-relay consider to be cost effective solution and most ISPs across the globe provide frame relay services. Inverse-ARP is enabled by default on Cisco routers. Rédigé par Noël NICOLAS le 18 décembre 2017 Temps de lecture : 5 minutes. 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. You can connect LANs with backbones Over T1/E1 lines using frame-relay. It is accessed primarily by a Virtual Cross Connection and data link layer VC Encapsulation, but is not bound to them by any of its attributes. Thus, if the Frame-Relay switch is configured correctly, the frame-relay interface-dlci command could theoretically be removed, and the frame-relay connection will still work. Advantages. A. Frame relay is a WAN technology. Frame-relay requires a frame-relay switch that “switches” one DLCI to another, creating a virtual circuit. 1 The address field of a frame is 01101000 00001111.
