Over deze vertaling

Cisco heeft dit document vertaald via een combinatie van machine- en menselijke technologie om onze gebruikers wereldwijd ondersteuningscontent te bieden in hun eigen taal. Houd er rekening mee dat zelfs de beste machinevertaling niet net zo nauwkeurig is als die van een professionele vertaler. Cisco Systems, Inc. is niet aansprakelijk voor de nauwkeurigheid van deze vertalingen en raadt aan altijd het oorspronkelijke Engelstalige document (link) te raadplegen.

Inleiding

Deze voorbeeldconfiguratie toont een hub en het gesproken ontwerp van IPsec tussen drie routers. Deze configuratie verschilt van andere hub en spuitconfiguraties omdat in dit voorbeeld communicatie tussen de spuitsites mogelijk wordt gemaakt door de hub. Met andere woorden, er is geen directe IPsec-tunnel tussen de twee spaakrouters. Alle pakketten worden over de tunnel naar de hub router verzonden waar het hen uit de IPsec-tunnel die met de andere gesproken router wordt gedeeld, herverdeelt. Deze configuratie is mogelijk als resultaat van de resolutie naar Cisco bug-ID CSCdp09904 (alleen geregistreerde klanten). Deze oplossing is geïntegreerd in Cisco IOS® softwarerelease 12.2(5)en deze release is de minimale vereiste voor deze configuratie.

Om de generieke Routing Encapsulation (GRE)-tunnel via IPSec met OSPF te configureren verwijst u naar het configureren van een GRE-Tunnel via IPSec met OSPF.

Om de basisconfiguratie van Cisco IOS® Firewall te configureren op een GRE-tunnel met netwerkadresomzetting (NAT), raadpleegt u Router-naar-router IPSec (Pre-Shared Keys) configureren op GRE-tunnels met IOS-firewall en NAT.

Voorwaarden

Vereisten

Dit document vereist een basisbegrip van IPsec-protocol. Raadpleeg een Inleiding naar IP Security (IPSec) encryptie om meer te weten te komen over IPsec.

Het doel van dit document is ervoor te zorgen dat tussen deze routers versleuteld:

  • 192.168.1.0/24 (Spoke 2) tot 10.1.1.0/24 (Hub)

  • 172.16.1.0/24 (Spoke 1) t/m 192.168.1.0/24 (Spoke 2)

Gebruikte componenten

Voeg een ander woord toe

Als u een andere SPA-router (sprak3) aan de bestaande hub-router wilt toevoegen naast sprak1 en sprak2, is het enige dat nodig is de creatie van een nieuwe LAN-to-LAN (L2L)-tunnel van het knooppunt tot aan sprak3. Maar aangezien slechts één crypto-kaart per fysieke interface kan worden geconfigureerd, moet u dezelfde crypto-map gebruiken wanneer u deze tunnel toevoegt. Dit is mogelijk wanneer u verschillende lijnnummers gebruikt voor elke externe site.

Opmerking: de crypto-kaart moet mogelijk worden verwijderd en opnieuw op de interface worden toegepast wanneer de nieuwe tunnelingang wordt toegevoegd. Wanneer de crypto kaart wordt verwijderd worden alle actieve tunnels gewist.

Verifiëren

Gebruik dit gedeelte om te bevestigen dat de configuratie correct werkt.

Het Uitvoer Tolk (uitsluitend geregistreerde klanten) (OIT) ondersteunt bepaalde show opdrachten. Gebruik de OIT om een analyse van tonen opdrachtoutput te bekijken.

Om deze configuratie te verifiëren, probeer een uitgebreide ping opdracht uit het Ethernet1 interfaceadres op Spoke 1, bestemd voor het Ethernet1 interfaceadres in Spoke 2 te halen.

  • Ping-gebruikt om de basisnetwerkconnectiviteit te diagnosticeren.

  • toon crypto ipsec sa-toont de instellingen die worden gebruikt door huidige (IPSec) veiligheidsassociaties (SAs).

  • toon crypto isakmp sa - toont alle huidige IKE SAs bij een peer.

  • tonen de crypto motor verbindingen actief—toont het aantal pakketten die over elke IPSec SA worden verzonden.

Uitvoer voorbeeld

Deze output komt van de show crypto motor connecties actieve opdracht die op de Hub router wordt uitgegeven. 

Hub#show crypto engine connections active

ID Interface IP-Address State Algorithm Encrypt Decrypt
5 Ethernet0 10.1.4.1 set HMAC_MD5+DES_56_CB 0 0
6 <none> <none>  set HMAC_MD5+DES_56_CB 0 0
2000 Ethernet0 10.1.4.1 set HMAC_MD5+DES_56_CB 0 10
2001 Ethernet0 10.1.4.1 set HMAC_MD5+DES_56_CB 10 0
2002 Ethernet0 10.1.4.1 set HMAC_MD5+DES_56_CB 0 10
2003 Ethernet0 10.1.4.1 set HMAC_MD5+DES_56_CB 10 0

Uit dit voorbeeld kan je zien dat elke tunnel 10 pakketten versleutelde en decrypteerde, wat bewijst dat het verkeer door de Hub router kwam.

Opmerking: Er worden twee IPsec SA's gemaakt voor elke peer (één in elke richting). In de router hub bijvoorbeeld zijn er vier IPsec SAs gemaakt voor twee peers.
