  15. Create route table DRG1rt in HubVCN1.
  16. Add two route rules to the route table DRG1rt: one to forward traffic targeted for the client subnet of VCN1 to HubLPG1, and a second to forward traffic targeted for the client subnet of VCN2 to HubLPG2.
    Destination Target Type Target Route Type Description
    10.10.1.0/24 LPG HubLPG1 Static Traffic to the client subnet of VCN1

    1. Select the autogenerated DRG route table for VCN attachments.
    2. Select the existing route table DRG1rt.
    3. Select VCN CIDR blocks.
  18. Create a remote peering connection in DRG1, named RPC1.
  19. Add a route rule to HubLPG1rt to forward traffic targeted for the client subnet of VCN3 to DRG1.
    Destination Target Type Target Route Type Description
    10.30.1.0/24 DRG DRG1 Static Traffic to the client subnet of VCN3
  20. Add a route rule to HubLPG2rt to forward traffic targeted for the client subnet of VCN3 to DRG1.
    Destination Target Type Target Route Type Description
