High Availability of Node Manager

The SMF supports IPAM redundancy and load balancing for each UPF. The IPAM running in the Node Manager microservice has two IPAM instances that are associated to each UPF. When one IPAM instance is inactive, the other IPAM instance manages the address allocation requests for the UPF.

For more information on node manager redundancy, see the IPAM Redundancy Support Per UPF section in the IP Address Management chapter.
