Asegúrate de revisar las funciones compatibles y no compatibles en las redes de VPC con el perfil de red RDMA. Si intentas configurar
funciones no compatibles, Google Cloud devuelve un error.
Crea una red con el perfil de red de RDMA
Para crear una VPC con el perfil de red de RDMA, haz lo
siguiente.
Consola
En la consola de Google Cloud , ve a la página Redes de VPC.
En el campo Nombre, ingresa un nombre para la red.
Selecciona Configurar el perfil de red y haz lo siguiente:
En el campo Zona, selecciona la zona del perfil de red que
deseas usar.
La red de VPC que creas está restringida a
esta zona, lo que significa que solo puedes crear recursos en la
red en esta zona.
Selecciona el perfil de red de RDMA para la zona que seleccionaste anteriormente, como europe-west1-b-vpc-roce.
Para ver el conjunto de funciones compatibles con el perfil de red que
seleccionaste, haz clic en Obtener vista previa de las funciones del perfil de la red.
En la sección Subred nueva, especifica los siguientes parámetros de configuración para una subred:
En el campo Nombre, ingresa un nombre para la subred.
En el campo Región, selecciona la región en la que deseas crear la
subred. Esta región debe corresponder a la zona del perfil de
red que configuraste. Por ejemplo, si configuraste el
perfil de red para europe-west1-b, debes crear la subred
en europe-west1.
Si seleccionas un rango que no es una dirección RFC 1918, confirma que el rango no entre en conflicto con una configuración existente. Para obtener
más información, consulta Rangos de subredes IPv4.
Haz clic en Listo.
Para agregar más subredes, haz clic en Agregar subred y repite los pasos anteriores.
También puedes agregar más subredes a la red después de haberla
creado.
NETWORK_PROFILE: es el nombre específico de la zona del
perfil de red, como europe-west1-b-vpc-roce.
El perfil de red de RDMA no está disponible en todas las zonas. Para ver las
instancias específicas de la zona del perfil de red que están disponibles,
sigue las instrucciones para
enumerar los perfiles de red.
NETWORK: es el nombre de la red de VPC
que contiene la subred nueva.
PRIMARY_RANGE: es el rango IPv4 principal para la subred
nueva, en notación CIDR. Para obtener más información, consulta Rangos de subredes
IPv4.
REGION: es la región Google Cloud en la que se crea la
subred nueva. Debe corresponder a la zona del perfil de
red que configuraste. Por ejemplo, si configuraste el
perfil de red europe-west1-b-vpc-roce, debes crear la
subred en europe-west1.

If you attempt to\nconfigure unsupported features, Google Cloud returns an error.\n\nCreate a network with the RDMA network profile\n----------------------------------------------\n\nTo create a VPC network with the RDMA network profile, do the\nfollowing. \n\n### Console\n\n1. In the Google Cloud console, go to the **VPC networks** page.\n\n\n [Go to VPC networks](https://console.cloud.google.com/networking/networks/list)\n\n \u003cbr /\u003e\n\n2. Click **Create VPC network**.\n\n3. In the **Name** field, enter a name for the network.\n\n4. In the **Maximum transmission unit (MTU)** field, select `8896`.\n\n5. Select **Configure network profile** and do the following:\n\n 1. In the **Zone** field, select the zone of the network profile that you want to use. The VPC network that you create is constrained to this zone, which means that you can only create resources in the network in this zone.\n 2. Select the RDMA network profile for the zone that you selected previously, such as `europe-west1-b-vpc-roce`.\n 3. To view the set of supported features for the network profile that you selected, click **Preview network profile features**.\n6. In the **New subnet** section, specify the following configuration\n parameters for a subnet:\n\n 1. In the **Name** field, enter a name for the subnet.\n 2. In the **Region** field, select the region in which to create the subnet. This region must correspond to the zone of the network profile that you configured. For example, if you configured the network profile for `europe-west1-b`, then you must create the subnet in `europe-west1`.\n 3. Enter an **IPv4 range** . This range is the [primary IPv4\n range](/vpc/docs/vpc#vpc_networks_and_subnets) for the subnet.\n\n If you select a range that is not an RFC 1918 address, confirm that\n the range doesn't conflict with an existing configuration. For more\n information, see [IPv4 subnet\n ranges](/vpc/docs/subnets#ipv4-ranges).\n 4. Click **Done**.\n\n7. To add more subnets, click **Add subnet** and repeat the previous steps.\n You can also [add more subnets](/vpc/docs/create-modify-vpc-networks#add-subnets) to the network after you\n have created the network.\n\n8. Click **Create**.\n\n### gcloud\n\n1. To create the network, use the [`gcloud compute networks create` command](/sdk/gcloud/reference/compute/networks/create)\n and specify the `--network-profile` flag.\n\n ```\n gcloud compute networks create NETWORK \\\n --subnet-mode=custom \\\n --network-profile=NETWORK_PROFILE\n ```\n\n Replace the following:\n - \u003cvar translate=\"no\"\u003eNETWORK\u003c/var\u003e: a name for the VPC network\n - \u003cvar translate=\"no\"\u003eNETWORK_PROFILE\u003c/var\u003e: the zone-specific name of the\n network profile, such as `europe-west1-b-vpc-roce`\n\n The RDMA network profile isn't available in all zones.
