I am trying to figure out how to deploy MRA in the following scenario for an ITC that hosts CM services for customers:
Single cluster of Expressway Core and Edge (X8.6.1)
Session Manager Edition (SME) (10.5.2 SU2A)
3 CUCM leaf clusters (10.5.2 SU2A)
Each leaf cluster has IM&P (Latest 10.5.2)
Intercluster peers for IM&P configured
SME setup as ILS hub and all leaf clusters as ILS spoke
SIP / Voice services domain is the same across all clusters
Here are my questions:
1. I know that I have to have each Unified CM cluster in the Expressway Core configuration. Do I have to add SME as well?
2. Would the internal UDS SRV records just point to the SME or would I need UDS records for each CUCM cluster?
a. I know that ILS will advertise the user's home cluster, but unsure if just having UDS records pointing to SME would suffice
I have attached a topology diagram of the setup I am attempting. Any help would be greatly appreciated!
