# VPC Peering Connections

VPC peering connection is a network connection between two VPCs. Through this connection, the instances in different VPCs can communicate with each other as if they are in the same network.

# Precautions

  1. EMQX Cloud only supports creating peering connection at the same region.
  2. EMQX Cloud does not accept CIDR in the range of 10.11.1.0/24 ~ 10.64.255.0/24.
  3. Peering connections are bound to resources. Please create peering connections before creating resources.

  2. Fill in the vpc information. (You could get the information from VPC Peering section of the deployment console)

    vpc_info

    vpc_info

  3. When the connection status is Inactive, go back to the deployment console to accept the peering request. Fill in the vpc information of the confluent cloud cluster and click Confirm. When the vpc status turns to running, you successfully create the vpc peering connection.
