Bhe, sperando che questo thread possa essere utile, voglio proporvi, delle topologie che includono un cloud frame relay.

in molti esercizi infatti, si ha bisogno di creare un cloud, ma forse i nuovi studenti non sanno che è sufficiente un router per fare da switch frame-relay e permettervi di effettuare i laboratori con molta facilità..

iniziamo con la prima e più classica topologia...

qui ho usato un cisco 2610 con 2 WIC 2-T (quindi 4 smart serial in totale) come switch frame-relay.

la topologia consite in un router che è l'hub, ovvero quello della sede principale, che si connette a 3 router diversi ognuno con un proprio PVC, in quelle che possiamo immaginare essere sedi remote (i branch routers)

ecco un immagine della topologia, poi la configurazione del router all'interno del cloud.

spero che la prima topologia possa essere utile

quest'altra topologia invece, si presenta in maniera diversa...

abbiamo due routers, WAN1 e WAN2 che dovrebbero appartenere alla sede principale, principalmente uno dovrebbe essere il back up dell'altro. Questa topologia è quella che ho incontrato studiando il terzo capitolo (su EIGRP) dell'esame ROUTE per la CCNP (642-902)

ecco la topologia, e poi la configurazione del router nel cloud. come prima un 2600 con 4 seriali
