Considerazioni su MTU

L'unità massima di trasmissione (MTU) è la dimensione in byte del pacchetto più grande supportato da un protocollo del livello di rete, che include sia le intestazioni sia il payload del pacchetto IP.

I pacchetti di rete inviati tramite un tunnel VPN vengono criptati e poi incapsulati in un pacchetto esterno in modo da poter essere instradati. I tunnel Cloud VPN utilizzano IPsec ed ESP per la crittografia e l'incapsulamento. Poiché il pacchetto interno incapsulato deve rientrare nell'MTU del pacchetto esterno, il suo payload massimo del pacchetto IP deve essere inferiore.

La VPN ad alta disponibilità su Cloud Interconnect non supporta i frame jumbo per i collegamenti VLAN criptati.

Incapsulamento ed elaborazione dei pacchetti

Per trasmettere correttamente i pacchetti utilizzando i tunnel Cloud VPN, devi attivare la pre-frammentazione sul gateway VPN del tuo peer in modo che i pacchetti inviati vengano frammentati prima di essere criptati e incapsulati.

Quando un tunnel Cloud VPN elabora i pacchetti destinati alla rete peer:

  • Cloud VPN utilizza il capping MSS per garantire che i pacchetti TCP rientrino nell'MTU del payload prima dell'incapsulamento IPsec.

  • Per altri protocolli, Cloud VPN elabora i pacchetti prima dell'incapsulamento IPsec come segue:

    • Se il bit DF del pacchetto è impostato e il gateway Cloud VPN determina che è necessaria la frammentazione, invia al mittente un messaggio ICMP Fragmentation Needed (IPv4) o ICMPv6 Packet Too Big. L'invio di messaggi ICMP o ICMPv6 richiede la configurazione di regole firewall di autorizzazione in entrata applicabili al mittente della VM Compute Engine: una regola per consentire l'ingresso ICMP e, per le VM dual-stack, un'altra regola per consentire l'ingresso ICMPv6.
    • Se il bit DF del pacchetto non è impostato e il gateway Cloud VPN e il pacchetto superano l'MTU del payload, il gateway Cloud VPN tenta di inviare il pacchetto. Il pacchetto potrebbe essere ignorato da un hop successivo dopo il tunnel Cloud VPN se è troppo grande per l'hop successivo.

Per informazioni generali su come i protocolli gestiscono le MTU non corrispondenti, consulta MTU non corrispondenti, limitazione MSS, rilevamento MTU del percorso nella documentazione relativa alle MTU della VPC.

MTU del gateway e MTU del payload

Cloud VPN distingue l'MTU del gateway Cloud VPN dall'MTU del payload Cloud VPN. L'MTU del gateway Cloud VPN è:

  • 1460 byte per i tunnel Cloud VPN
  • 1440 byte per la VPN ad alta disponibilità su Cloud Interconnect

Configura il gateway VPN peer in modo che utilizzi un MTU corrispondente all'MTU del gateway Cloud VPN corrispondente.

L'MTU del payload per un tunnel Cloud VPN dipende dai cifrari configurati per l'utilizzo del tunnel e dal fatto che il gateway utilizzi interfacce IPv4 o IPv6. Per ulteriori informazioni, consulta Valori MTU del payload di Cloud VPN.

MTU nei gateway VPN ad alta disponibilità con interfacce IPv6

L'MTU del gateway è lo stesso sia nei gateway VPN ad alta disponibilità con interfacce IPv6 sia nei gateway VPN ad alta disponibilità con interfacce IPv4. Tuttavia, poiché gli intestazioni IPv6 sono più grandi di quelle IPv4, l'MTU del payload di un gateway con interfacce IPv6 è sempre inferiore di 20 byte rispetto all'MTU del payload di un gateway VPN ad alta disponibilità con indirizzo IPv4 identico.

Ad esempio, un gateway VPN ad alta disponibilità con interfacce IPv4 che utilizzano metodi di crittografia non AEAD ha un MTU del gateway di 1460 byte e un MTU del payload di 1406 byte. Un gateway VPN ad alta disponibilità con interfacce IPv6 che utilizzano crittografia non AEAD ha un'MTU del gateway di 1440 byte e un'MTU del payload di 1386 byte.

Per ulteriori informazioni, consulta Unità massima di trasmissione.
