OCI Networking: implementing Route Table Propagation Between VCNs in Terraform
Does anyone know how to I've looked through the documentation and I'm still confused about I'm trying to configure I'm currently setting up a network architecture on Oracle Cloud Infrastructure (OCI) using Terraform, and I'm working with issues with route table propagation between two Virtual Cloud Networks (VCNs)..... I have two VCNs, one for production and one for development, and I'm trying to establish communication between them using VCN peering. However, despite the peering being established successfully, instances in the production VCN want to reach instances in the development VCN. Here's a snippet of my Terraform code for the route tables: ```hcl resource "oci_core_route_table" "prod_route_table" { compartment_id = var.compartment_id vcn_id = oci_core_virtual_cloud_network.prod_vcn.id route_rules = [ { destination = oci_core_virtual_cloud_network.dev_vcn.cidr_block destination_type = "CIDR" network_entity_id = oci_core_virtual_cloud_network.dev_vcn.id } ] } resource "oci_core_route_table" "dev_route_table" { compartment_id = var.compartment_id vcn_id = oci_core_virtual_cloud_network.dev_vcn.id route_rules = [ { destination = oci_core_virtual_cloud_network.prod_vcn.cidr_block destination_type = "CIDR" network_entity_id = oci_core_virtual_cloud_network.prod_vcn.id } ] } ``` I have confirmed that the security lists and network security groups allow the necessary ingress and egress rules. However, I still encounter the behavior: "Network unreachable" when trying to ping an instance in the development VCN from production. I've also verified that the VCNs are in the same region and that the peering connection is active. I suspect there might be an scenario with how I'm configuring the route tables or the peering connection. Any insights on how to ensure proper route propagation would be greatly appreciated! I recently upgraded to Hcl stable. Am I approaching this the right way? My development environment is Windows 10. Thanks, I really appreciate it!
