In alcuni ambienti, potrebbe essere necessario raggruppare più collegamenti seriali in modo che funzionino come un unico collegamento con larghezza di banda aggregata. Questo documento descrive come configurare i router Cisco 4500 in modo che includano quattro interfacce seriali con un'interfaccia di modello virtuale.
Questa configurazione può essere utilizzata per i router connessi su linee affittate o per i router che dispongono dell'unità CSU/DSU (Channel Service Unit). A seconda delle esigenze, è possibile aggiungere ulteriori funzionalità alla configurazione.
Nessun requisito specifico previsto per questo documento.
Le informazioni fornite in questo documento si basano sulle versioni software e hardware riportate di seguito.
Router Cisco 4500 in un ambiente lab non configurato.
Cisco IOS® versione 12.2(10b) era in esecuzione su entrambi i router.
Le informazioni discusse in questo documento fanno riferimento a dispositivi usati in uno specifico ambiente di emulazione. Su tutti i dispositivi menzionati nel documento la configurazione è stata ripristinata ai valori predefiniti. Se la rete è operativa, valutare attentamente eventuali conseguenze derivanti dall'uso dei comandi.
Questa configurazione può essere utilizzata anche con le seguenti versioni hardware e software.
Due router qualsiasi con quattro interfacce seriali ciascuna.
È possibile utilizzare interfacce seriali WIC-1T e WIC-2T.
Per ulteriori informazioni sulle convenzioni usate, consultare il documento Cisco sulle convenzioni nei suggerimenti tecnici.
In questa sezione vengono presentate le informazioni necessarie per configurare le funzionalità descritte più avanti nel documento.
Nota: per ulteriori informazioni sui comandi menzionati in questo documento, usare lo strumento di ricerca dei comandi (solo utenti registrati).
Questo documento utilizza le impostazioni di rete mostrate nel diagramma sottostante.
Questa configurazione è stata testata con il software Cisco IOS versione 12.2(10b) sui router serie 4500. Gli stessi concetti di configurazione si applicano a una topologia di router simile o ad altre versioni di Cisco IOS.
Questo documento utilizza le configurazioni mostrate di seguito.

Configurare quanto segue per implementare la configurazione precedente:
multilink virtual-template
interface modello-virtuale
PPP multilink in ciascuna delle interfacce seriali in cui deve essere eseguito il bundling.
RIP come protocollo di routing IP
Il loopback 0 dell'interfaccia è configurato in modo da non causare mai errori e il loopback 0 senza numero ip migliora il bundling di più di cinque interfacce seriali con lo stesso indirizzo IP.
Quando tutte le interfacce seriali sono attive e il traffico utente deve essere inviato, Multilink PPP crea un'interfaccia di accesso virtuale e viene eseguita la negoziazione PPP. La configurazione per questa interfaccia di accesso virtuale viene duplicata dal modello virtuale. Il numero di interfacce seriali attive è incluso in questa interfaccia di accesso virtuale e viene creata una larghezza di banda aggregata.
Le informazioni contenute in questa sezione permettono di verificare che la configurazione funzioni correttamente.

Alcuni comandi show sono supportati dallo strumento Output Interpreter (solo utenti registrati); lo strumento permette di visualizzare un'analisi dell'output del comando show.
Nota: prima di usare i comandi di debug, consultare le informazioni importanti sui comandi di debug.
debug ppp negotiation: per vedere se un client sta passando una negoziazione PPP; questo comando viene utilizzato per verificare la presenza di una negoziazione degli indirizzi.
debug ppp authentication: consente di verificare se un client sta passando l'autenticazione. Se si usa una versione del software Cisco IOS precedente alla 11.2, usare il comando debug ppp chap.
debug ppp error: consente di visualizzare gli errori di protocollo e le statistiche sugli errori associate alla negoziazione e al funzionamento della connessione PPP.
debug vtemplate: per visualizzare la copia del modello virtuale per creare un'interfaccia di accesso virtuale.
debug degli eventi di connessione multipla ppp - Per visualizzare il debug degli eventi di connessione multipla PPP. Visualizza informazioni sugli eventi che interessano i gruppi di connessione multipla.
show ppp multilink: consente di visualizzare i membri del fascio di connessione multipla.
