unable to ping from one instance to another instance (Different AWS account) through VPC peering**
As a part of learning I have created VPC peering between two different AWS account similar region
1.VPC A (vpc-0101125afe156bXXX) created in my account 1(Ohio) - with EC2 instance test1 (173.15.2.42 )has been launched.
2.VPC B (VPC-09abfe7f4c7c7cX7XX) created other Account child(Ohio)- with EC2 instance test2 (10.50.3.180) has been launched.
- VPC peering(pcx-ola8829c615XXXX) has created between two VPC of different accounts (let say region Ohio)
4.To enable the traffic between two vpc,either VPC IP range has updated in route tables
Now
- ping test from from instance test 2 (10.50.3.180) to EC2-instance test1 (173.15.2.42 ) was successful
*ubuntu@ip-10-50-3-180:~$* ping 173.15.2.42

- **Now I was try to ping from Ec2 Instance test1 (173.15.2.42) to Ec2 instance test2 (10.50.3.180). It was showing nothing on the terminal.
[ec2-user@ip-173-15-2-42 ~]$ ping 10.50.3.180

I am able to ping an instance (test 2) residing in the VPC of master account to instance test 1 residing in child account and vice versa but I'm unable to ping that instance (test1) from an instance ( test2)residing in the master account ?
