Allow federated DCs to communicate with Connect but keep separate configs

Hello,
I’m trying to set several consul datacenter that are able to communicate with one another but would also keep their own configuration (I’ve to implement a mix of single & multi tenant architecture) .
Since I use terraform with templates, I’ll try to prefix every service with its DC name so they don’t overlap but is there a more idiomatic way to achieve this ?
Best,

Hello,
Prefixing services actually works (I still have to dive deeper in acl management in order to enforce the segregation, though)

Can someone confirm that what I observe is actually the expected behavior : the configuration of a service in 2 distinct datacenters is globally shared when they’re wan joined ?
Best,
Matthieu
