Default Root distribution from the closed network

[User1101]

1.
Is it possible to have BGP distribute the default route (0.0.0.0.0/0) from the closed network to the OCI side?

VM ⇒ Cloud Router ⇒ Interconnect ⇒ On Premise Router

2.
If the Internet Gateway is built in the VPC, is it correct to consider not to bat the route (0.0.0.0/0 is batting)?

I mistook the question. I changed the question.

OCI　⇒　Google Cloud
