Geo Switchover

The SMF achieves geo switchover by transparently migrating service IP address to mated peer K8s cluster, rack collocated, or geo-located. During the NF start-up, all the K8s cluster Namespaces register with the next-hop BGP router to advertise its service IP address and local IP address along with the priority and route modifier values.

Each logical NF exposes separate NF instance toward NRF or DNS, separate configuration, and separate LCM for a Namespace.
