Dit document beschrijft hoe u een Dynamic Virtual Tunnel Interface (DVTI) kunt configureren op Secure Firewall 9.20.
De informatie in dit document is gebaseerd op de volgende softwareversies:
Opmerking: de informatie in dit document is gemaakt van de apparaten in een specifieke laboratoriumomgeving. Alle apparaten die in dit document worden beschreven, hadden een opgeschoonde (standaard)configuratie. Als uw netwerk live is, moet u zorgen dat u de potentiële impact van elke opdracht begrijpt.
Dynamic Virtual Tunnel Interfaces (DVTI’s) kunnen zeer veilige en schaalbare connectiviteit bieden voor Virtual Private Networks (VPN’s) met externe toegang.
DVTI's kunnen worden gebruikt voor zowel hub als spraakconfiguratie. De tunnels bieden een afzonderlijke virtuele toegangsinterface op aanvraag voor elke VPN-sessie.
1. De spoke initieert een IKE uitwisselingsverzoek met de hub voor een verbinding van VPN.
2. De hub authenticeert de spaak.
3. Het Cisco Secure Firewall Management Center wijst een dynamische virtuele sjabloon toe aan de hub.
4. De virtuele sjabloon genereert dynamisch een virtuele toegangsinterface op de hub. Deze interface is uniek voor de VPN-sessie per spaak.
5. De hub creëert een dynamische VTI-tunnel met de spaak die gebruikmaakt van de virtuele toegangsinterface.
6. De hub en spoke-uitwisselingsverkeer via de tunnel die gebruik maakt van dynamische routingprotocollen (BGP/OSPF/EIGRP) of met beveiligde netwerken (Multiple-Security Association VTI).
7. Dynamische VTI’s werken zoals elke andere interface, zodat u QoS, firewallregels, routeringsprotocollen en andere functies kunt toepassen zodra de tunnel actief is.
8. Er wordt één DVTI gemaakt op het HUB-apparaat en meerdere statische tunnelinterfaces voor meerdere externe/spraaksites.
In dit artikel kunnen BGP, OSPF en EIGRP worden getest via DVTI.
Opmerking: Cisco Secure Firewall voegde ondersteuning toe voor DVTI op versie 7.3 en ondersteunt momenteel slechts één DVTI per Cisco bug-id CSCwe13781.

Om OSPF problemen op te lossen, gebruik deze debugs en toon bevelen:
debug ip ospf
debug ip ospf packet
debug ip ospf events
debug ip ospf hello
debug ip ospf adj
show ospf
show ospf neighbor
show ospf interface
Om EIGRP problemen op te lossen, gebruik deze debugs en toon bevelen:
debug ip eigrp
debug ip eigrp neighbor
debug ip eigrp notifications
show eigrp
show eigrp
show eigrp interfaces show eigrp neighbors show eigrp topology
Om BGP problemen op te lossen, gebruik deze debugs en toon opdrachten:.
debug ip bgp all
debug ip bgp updates
debug ip bgp events
show bgp
show bgp summary
show bgp neighbors
Om IKEv2 problemen op te lossen, gebruikt u deze debugs en toont u opdrachten:
debug crypto ikev2 protocol 255
debug crypto ikev2 platform 255
debug crypto ipsec 255
