Connection limitations
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.
The fee for a cross-region peering connection is paid by the requester of the connection.
If the acceptor 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 when the connection is connected.
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.
There is no bandwidth cap for an intra-region peering connection, and a bandwidth cap must be set for a cross-region peering connection.
Resource limitations
