Hi @Aditya Khandelwal Thanks for reaching out. You will have two namespaces in Disaster Recovery, the idea is that the clients connect to the alias and then the failover is handled in the backend of SB. So, it would not make sense to use traffic manager in this case.
please refer this documentation to understand how the Disaster recovery setup works https://video2.skills-academy.com/en-us/azure/service-bus-messaging/service-bus-geo-dr#basic-concepts-and-terms.
you need to manually failover or you can automate failover either with monitoring systems, or with custom-built monitoring solutions. However, such automation takes extra planning and work as mentioned below

Do let me know if you have any queries.
