Assigning an Inter-Region Bandwidth
Scenarios
By default, a cloud connection provides 10 kbit/s of bandwidth for testing cross-region network connectivity.
To allow you to test network connectivity between regions, Cloud Connect provides 10 kbit/s by default. To test network connectivity, you can ping an ECS in one VPC from an ECS in the other VPC.
Constraints
If network instances are in the same region, they can communicate with each other by default after they are loaded to one cloud connection.
Assigning an Inter-Region Bandwidth
- Go to the Cloud Connections page.
- Click the name of the cloud connection to go to the Basic Information tab.
- Click the Inter-Region Bandwidths tab.
- Click Assign Inter-Region Bandwidth and configure the parameters based on Table 1.
Table 1 Parameters required for assigning an inter-region bandwidth Parameter
Description
Example Value
Regions
Specifies the regions of the network instances that need to communicate with each other.
Select two regions.
CN-Hong Kong
CN North-Ulanqab1
Bandwidth Package
Specifies the purchased bandwidth package that will be bound to the cloud connection.
bandwidthPackge-test
Bandwidth
Specifies the bandwidth you require for communication between regions, in Mbit/s.
The sum of all inter-region bandwidths you assign cannot exceed the total bandwidth of the bandwidth package. Plan the bandwidth in advance.
10
- Click OK.
Now the network instances in the two regions can communicate with each other.
The default security group rules deny all the inbound traffic. Ensure that security group rules in both directions are correctly configured for resources in the regions to ensure normal communication.
