Configurazione di GRE su IPSec tra un router Cisco IOS e un concentratore VPN 5000 con routing statico
Sommario
Introduzione
In questo documento viene descritto come configurare GRE (Generic Routing Encapsulation) su IPSec tra un Cisco VPN serie 5000 Concentrator e un router Cisco con software Cisco IOS®. La funzione GRE-over-IPSec è stata introdotta nel software VPN 5000 Concentrator 6.0(19).
Nell'esempio, il routing statico viene usato per indirizzare i pacchetti attraverso il tunnel.
Prerequisiti
Requisiti
Nessun requisito specifico previsto per questo documento.
Componenti usati
Le informazioni fornite in questo documento si basano sulle seguenti versioni software e hardware:
-
Cisco IOS Software Release 12.2(3)
-
Cisco VPN 5000 Concentrator software versione 6.0(19)
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.
Convenzioni
Per ulteriori informazioni sulle convenzioni usate, consultare il documento Cisco sulle convenzioni nei suggerimenti tecnici.
Configurazione
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).
Esempio di rete
Per la stesura di questo documento è stata utilizzata la configurazione di rete illustrata in questo diagramma.
Il GRE su IPSec è configurato tra il router 1720-1 con software Cisco IOS e il concentratore VPN 5002. Dietro al router e al VPN Concentrator, sono presenti più reti pubblicizzate tramite Open Shortest Path First (OSPF). OSPF viene eseguito all'interno del tunnel GRE tra il router e il concentratore VPN.
-
Queste reti sono dietro il router 1720-1.
-
10.1.1.0/24
-
10.1.2.0/24
-
10.1.3.0/24
-
-
Queste reti sono alla base di VPN 5002 Concentrator.
-
20.1.1.0/24
-
20.1.2.0/24
-
20.1.3.0/24
-
Configurazioni
In questo documento vengono usate le seguenti configurazioni.
Nota: con il software Cisco IOS versione 12.2(13)T e successive (codici T-train con numerazione superiore, 12.3 e successive), è necessario applicare la mappa crittografica IPSec configurata solo all'interfaccia fisica. Non è più necessario applicare la mappa crittografica sull'interfaccia del tunnel GRE. La disponibilità della mappa crittografica sulle interfacce fisiche e di tunnel quando si usa il software Cisco IOS versione 12.2(13)T e successive dovrebbe comunque funzionare, ma Cisco Systems consiglia di applicare la mappa crittografica solo sull'interfaccia fisica.
