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.
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 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.
This feature is in grayscale release in Nanjing and Tianjin. If you need to use it, please submit a ticket for consultation.
