I've worked on some experiments with AWS EC2. According to the doc you provided
and from my own experience, EC2Multiregionsnitich should be the right setting
as you have 2 different datacenters.
In cassandra.yaml: change seeds to public address list, change listen and rpc
address to private address, change broadcast address to public address, use
Ec2MultiRegionSnitch.
Hope it works!

Subject: Snitch for AWS EC2 nondefaultVPC
From: arunsandu...@gmail.com
To: user@cassandra.apache.org
Hi all,
All our nodes are launched in AWS EC2 VPC (private). We have 2 datacenters(1
us-east , 1- asiapacific) and all communication is through private IP's and
don't have any public IPs. What is the recommended snitch to be used? We
currently have GossipingPropertyFileSnitch.
1. If Ec2MultiRegionSnitch, then what would be the broadcast_address?
2. If not Ec2MultiRegionSnitch, which snitch better fits this environment?
Ref:
As per the document Ec2MultiRegionSnitch,set the listen_address to the private
IP address of the node, and the broadcast_address to the public IP
address of the node.
