Para se conectar a um recurso em uma rede externa (uma rede local ou
outra rede de nuvem privada virtual (VPC)), a rede externa e
a instância do Cloud Data Fusion precisam estar conectadas pela mesma
rede VPC.
Para conectar uma rede externa à rede VPC do Cloud Data Fusion usando túneis do Cloud VPN com roteamento de protocolo de gateway de borda (BGP) ou anexos de VLAN, faça o seguinte:
Verifique se as sessões do BGP no Cloud Router que gerenciam os
túneis do Cloud VPN ou os anexos da VLAN receberam prefixos
específicos (destinos) da rede externa. Não é possível importar rotas padrão
(destino 0.0.0.0/0) para a rede VPC do Cloud Data Fusion, porque essa rede tem uma
rota padrão local própria. As rotas locais de um destino são sempre usadas, mesmo que o
peering do Cloud Data Fusion esteja configurado para importar rotas personalizadas da
rede VPC.
Identifique as conexões de peering
produzidas pela conexão de serviços particulares. Dependendo do serviço, a
conexão de serviços privados pode criar uma ou mais das seguintes conexões de peering, mas não necessariamente todas elas:

Default routes (destination 0.0.0.0/0) cannot be imported into the Cloud Data Fusion VPC network because that network has its own local default route. Local routes for a destination are always used, even though the Cloud Data Fusion peering is configured to import custom routes from your VPC network.\n- [Identify the peering connections](/vpc/docs/configure-private-services-access#listing-connections) produced by the private services connection. Depending on the service, the private services connection might create one or more of the following peering connections, but not necessarily all of them:\n - `datafusion-googleapis-com`\n - `servicenetworking-googleapis-com`\n- [Update all of the peering connections](/vpc/docs/using-vpc-peering#update-peer-connection) to enable Export custom routes.\n- [Identify the allocated range](/vpc/docs/configure-private-services-access#listing_allocated_ip_address_ranges) used by the private services connection.\n- [Create a Cloud Router custom advertised route](/network-connectivity/docs/router/how-to/advertising-custom-ip) for the allocated range on the Cloud Routers managing BGP sessions for your Cloud VPN tunnels or VLAN attachments.\n\nWhat's next\n-----------\n\n- Learn how to [create a private instance in Cloud Data Fusion](/data-fusion/docs/how-to/create-private-ip)."]]
