The MRA config guides already

The MRA config guides already covers such scenario, have you reviewed them?

Dear Jaime,

Sushant Sharma — Mon, 23 May 2016 06:40:49 GMT

Dear Jaime,

There is no such guide for this type of configuration.

please check below what i have done

1) Solution 1 : I tried to add both cucm cluster in expressway

2) Solution 2 : i made ILS communcation between these two cluster but still its not working .

Can you confirm the CUCM

Can you confirm the CUCM versions?

I have this working with one cluster in version 9.12 and another cluster in version 10.

Under Advanced Features....ClusterView you will need to enable TFTP and UDS Sync. See attached Image.

Also I have _cisco-uds dns fields for all servers in both clusters.

Dear Edip,

Dear Edip,

Thanks for information

I have checked both the boxes TFTP and UDS in both cluster

But still no chance

cucm version : 10.5 X side

cucm version : 11.1 Y side

Can you please explain your scenario how u did this deployment might be i am missing some configuration

I have added both cucm and IMP cluster inside the expressway core

Does internal registration

Does internal registration works with only one SRV record and ILS between clusters??

If not, you need to fix that in first place.

Your scenario in the guides would be:

Multiple Clustered Network Elements
In this scenario there are multiple clusters of each network element.

The difference is you don't have another EXP-C/EXP-E cluster for redundancy.

Dear Jamie,

Why i need to configure ILS between my cluseter

Because expressway support multiple deployment so we can directly add our cucm and Cups cluster inside the deployment .

I have only issue now below the comment from deployment guide

"You cannot associate one domain with more than one deployment. Similarly, each Unified Communications node may only be associated with one deployment."

Because MRA uses the SRVs to

Jaime Valencia — Mon, 30 May 2016 14:48:12 GMT

Because MRA uses the SRVs to register the devices, and even if the SRVs are pointing to both clusters, chances are you might direct them to the "wrong cluster", ILS will then do the lookup, and direct them to the right cluster.
