Questions around MRA and SME cluster

[Nick Halbert-Lillyman]

Does anyone have any experience or insight around using a single cluster of Expressway-C/E to service multiple CUCM clusters behing CUCM SME edition?

Reading through the MRA deployment guide, it does mention deploying MRA to multiple CUCM clusters, but it doesn't mention an SME cluster specifically.  I'm trying to figure out if I should point the Expressway-C to each CUCM/IM&P publisher node, or to just point to the SME publisher and let ILS service do the rest?

You need to add all the CUCM clusters as the neighbor zone needs to be between each server and EXP-C for MRA to work.

What you'd do, is point the SRVs to the SME cluster so it can re-direct the registration request to the right cluster, and then use the neighbor zone to proxy the signaling.

Awesome thanks Jamie, does that apply to both UDS and Cuplogin SRV records?

You don't need cuplogin SRV anymore, it works just fine with UDS SRV only.
