Apigee hybrid Cassandra port - CS ring secure ports

Per listed doc Secure ports usage | Apigee | Google Cloud

Q: Do port 7199 is also required when having Cassandra ring between public cloud runtime (Cassandra) runtime and on premise (Cassandra) Apigee hybrid runtime in different regions ?

Note: Per link (Advanced Apigee Hybrid Cassandra Operations (googlecloudcommunity.com)) it indicated only 7000 and 7001 is enough and does not indicate anything for 7199 for Cassandra ring between two regions

I would stick to the official doc requirements ie 7199, 7001
