CEN automatically realizes the multi-node adaptive routing forwarding and distribution. The adaptive routing process improves the network performance.

View CEN routes on the CEN console

You can view routes of networks in other regions learned by the CEN instance. For example, a CEN instance has attached a VPC in China North 1 (Qingdao) and another VPC in China North 2 (Beijing). You can follow these steps to view routes learned from the VPC in China North 1.

To view the learned routes, complete these steps:

  1. Log on to the CEN console.
  2. Click the ID of the target CEN instance.
  3. Click Routes and select the region to query.

    Descriptions of fields in a route entry are as follows:

    Field Description
    Region The region of the routes to query.
    CIDR Block The learned CIDR block.
    Destination Region The region of the learned CIDR block.
    Destination Network ID The network to which the destination CIDR block belongs.
