I am using two google managed services i.e Google Cloud SQL and Google Cloud Data Fusion. The cloud data fusion private IP instance is deployed inside a google managed VPC(Let's call it A) which is peered with my custom VPC(Lets Call it B).
Now my Cloud SQL Postgres is also installed in google managed VPC(Lets call it C).
A <-> B (peered) B <-> C (peered)
Since A and C are google managed VPCs, I am not able to peer them. What should I do to make C accessible to A?
