Parameter description

**Table 2** Parameter description
Name	Type	Mandatory	Description
client_network_ranges	Array of strings	Yes	CIDR block where the client is located NOTE: Cross-CIDR access is required only when the CIDR blocks of the client and the replica set instance are different. For example, if the client CIDR block is 192.168.0.0/16 and the replica set instance's CIDR block is 172.16.0.0/24, add the CIDR block 192.168.0.0/16 so that the client can access the replica set instance. This function is available only for replica sets. For example, if the source network segment is 192.168.0.0/xx, the value of xx must range from 8 to 32. To ensure the ECS and the DB instance can communicate with each other, configure the connection by referring to VPC Peering Connection Overview.
