Creating AWS Elasticache Redis ReadReplica in EC2 instance

Question

I am trying to create a Redis Slave which will use Elasticache Redis as the master.

here are the steps I am following,

1 - Launch an EC2 instance in the same VPC and subnet as elasticache

2 - Install redis on it and bind it to its private IP. I am able to connect to Elasticache from here.

3 - Now, Run `SLAVEOF ELASTICACHE_IP ELASTICACHE_PORT` on the EC2 redis

So, Now all the keys which are present in Elasticache, should be available in the EC2 Redis also.

But it is not happening. Any reason why is it not happening? Am I making any mistake? OR does elasticache even allows this kind of stuff?
