This topic describes how to test the network connectivity between two network instances attached to a CEN instance.

Prerequisites

A cross-region connection bandwidth is configured for the network instances if the two network instances belong to different regions. For more information, see Step 4: Set a cross-region connection bandwidth.

Background information

The following table describes two ECS examples that are deployed in China (Hangzhou) and China (Shanghai) respectively.
Configuration ECS 1 ECS 2
Private IP address: 192.168.1.41 192.168.136.60
Region China (Shanghai) China (Hangzhou)

Procedure

  1. Log on to ECS 2.
  2. Use ping command to ping the private IP address of ECS 1 to check whether the connection between ECS 1 and ECS 2 is successful.
