To connect to a resource in an external network (an on-premises network or
another Virtual Private Cloud (VPC) network), the external network and
Cloud Data Fusion instance must be connected through the same
VPC network.
To connect an external network to the Cloud Data Fusion VPC
network using Cloud VPN tunnels with border gateway protocol (BGP) routing or
VLAN attachments, do the following:
Ensure the BGP sessions on the Cloud Router managing your
Cloud VPN tunnels or VLAN attachments have received specific
prefixes (destinations) from your external network. 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.
Identify the peering 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:
