III.2.1.2BGP Example 1

Roberto Bifulco — Sat, 10/18/2008 - 22:11

Nel seguito è riportato un esempio di funzionamento di BGP:

Frame21

R1 impara una nuova rotta, tramite il protocollo di IGP, all'interno del suo AS, la comunica dunque agli AS confinanti che a loro volta propagano la rotta.

Supponiamo che cada il link fra AS10 ed AS20, quando AS20 non riceve più il messaggio di KEEPALIVE, provvede a cancellare tutte le rotte che passano per AS10, di conseguenza aggiorna anche la rotta precedentemente inviata ad AS30, inviando un nuovo messaggio di UPDATE:

Frame22
