Configuring VRF Name

Enable VRF name in the configuration of address pool. When “vrf-name” in the IP pool is configured with “@” character, the first part before “@” is treated as “VRF” name which is sent to UPF and the second part after “@” is sent as context name in N4 Association Update message.

When “vrf-name” in the IP pool is configured without “@” character, the entire name is sent as context name (existing behaviour) in N4 Association Update message.

The SMF sends the VRF name in N4 Session Establishment request if it is configured with “@” in the pool in “UE IP VRF” IE.

Use the following configuration to configure the VRF name:

configure 
   ipam  
      address-pool pool_name  
         vrf-name vrf_name 
         end 

NOTES:

  • ipam : Enters the IPAM configuration mode.

  • address-pool pool_name : Configures the address pool configuration. pool_name must be the name of the address pool.

  • vrf-name vrf_name : Specifies the name of the VRF for the pool.
