Unsupported VPC Peering Configurations
This page presents the VPC peering configurations that are not supported on the OUTSCALE Cloud.
Peering with Overlapping CIDR blocks
It is not possible to create a peering connection between VPCs that have overlapping CIDR blocks. This impossibility also applies to VPCs that have multiple CIDR blocks as long as any of these CIDR blocks overlap.
Peering with a Third Element
Peering with a Third VPC
Peered VPCs cannot communicate with other VPCs they are not directly peered with. That is, if VPC B and VPC C are each peered with VPC A, they cannot use it as a transit point to access each other.
Peering with a VPN Connection or DirectLink Connection
A VPC that has a VPN connection or a DirectLink connection cannot extend it to a peered VPC. That is, if VPC A is peered with VPC B and also has a VPN connection or a DirectLink connection, that connection is not extended to VPC B.
Peering with an Internet Gateway
A VPC that has an Internet gateway cannot extend it to a peered VPC. That is, if VPC A has an Internet gateway and VPC B does not, the connection between VPC A and VPC B is not extended to the Internet.
