Use Limits

Note the following when you use a peering connection:

  • To enable real communication between both ends of a peering connection, you must configure routing rules in the route tables of both the sending and receiving ends.
  • If the peer does not accept a peering connection request, the request will automatically expire after 7 days.
  • Do not accept peering connection requests from unknown accounts because they may pose risks to your network.
  • The VPC CIDR blocks on both ends of a peering connection cannot overlap. Otherwise, an error will occur.
  • For a cross-region peering connection, the CIDR blocks of multiple peer networks of one VPC cannot overlap. Otherwise, an error will occur.
  • Either end of a peering connection can interrupt the connection. Then, traffic between the two VPCs is disconnected immediately.
