Feature Description

With this feature, SMF enables you to perform the following tasks:

  • Allocate specific set of IP pools for edge UPFs in such a way that the UPFs do not share the same IP pool

  • Fall back to centrally located UPF when the edge UPF is down

This feature introduces new CLI command to tag the IP pools with a name, and associate this name while configuring UPF selection for each DNN. The IP address allocation to UPF is unique per pool if the tag configuration is based on location DNN. The UPFs share the same IP pool if the IPAM tag is configured with the default DNN received from the service.

For more information, refer to the IP Address Management chapter.
