Expressway MRA multiple Deployment in a single public domain

I need assist to find the best design to implement the following :

  • We have UC Cluster and expressway node working MRA fine here in Egypt and we need to deploy Expressway MRA in Dubai that has UC Cluster
  • Both have the same public domain
  • How can user login to nearest expressway.
  • How can Failover happen ?
  • How can user from Egypt login in case of being in Dubai and no user exists in DB there ?
  • I want the best design to make dubai users use MRA smoothly

Hi Ahmed,

For that, you need to enable Cisco Intercluster Lookup Service. Here is a good post on the configuration steps:
