I just created a public DNS zone in GCP, everything works fine except, when I go into network details I see following message "Requests can't be forwarded to peer network because the peer project disabled DNS peering"
What does it mean?

DNS peering is a type of zone in Cloud DNS that allows you to send DNS requests from a specific sub-domain to another Cloud DNS zone configured in another VPC—and it lets you do just that! DNS peering in action.
VPC Network Peering enables you to connect VPC networks so that workloads in different VPC networks can communicate internally. Traffic stays within Google's network and doesn't traverse the public internet. VPC Network Peering is useful in these environments: SaaS (Software-as-a-Service) ecosystems in Google Cloud.
The peering can be interesting when you want to share a VPN or Interconnect endpoint. You perform a peering between the interconnect project and these that want to reuse this connexion. With share VPC, you don't have the transitivity limitation, all the VM can be in the same VPC, even if there are in different project.
It's a known issue and Google is looking into it... however, it might not get fixed since it is "just a aesthetics issue"
