• Access Gateway Function (MX204, MX240, MX480, MX960, and MX10003)—Starting in Junos OS Release 22.3R1, we introduce the Access Gateway Function (AGF). AGF provides wireline traffic convergence by interworking wireline connected devices with the 5G Core (5GC). AGF is the access point for existing fixed network residential gateway (FN-RG) and is an integral part of the Junos Multi-Access User Plane solution. AGF supports the following capabilities:

  • DHCP relay and DHCPv6 stateful relay service for relay client negotiations to a DHCP server in the 5GC

  • PPPoE access to the 5GC

  • N1 proxy signaling for user equipment (UE) registration and Protocol Data Unit (PDU) session establishment procedures for FN-RG authentication, address assignment, and authorization

  • N2 signaling with the Access and Mobility Management Function (AMF)

  • N3 signaling to both an external and colocated user plane function (UPF) that supports per subscriber IP and IPv6 data connectivity to a data network

  • UE-level QoS that originate from the 5GC authorization

  • Colocation of AGF, broadband network gateway (BNG), and UPF services on a single MX Series router

  You can configure AGF services in the [edit services agf] hierarchy.

  [See AGF User Guide.]

• SCTP support (MX204, MX240, MX480, MX960, and MX10003)—In Junos OS Release 22.3R1, you can configure SCTP to connect the Access Gateway Function (AGF) with the Access and Mobility Management functions (AMFs). SCTP is a reliable connection-oriented protocol that you use for transporting message streams.

  • Multistream protocol

  • User data fragmentation

  • Chunk bundling

  • Packet validation

  • Multihome support

  AGF creates an SCTP association to communicate with the AMFs. You can configure the SCTP association in the [edit services agf amf] hierarchy.

  Use the show system connections | find sctp command to check the SCTP endpoints and associations.

  Use the show system statistics sctp command to query the SCTP system-wide statistics.

  [See AGF User Guide, show system statistics, and show system connections.]

• Support for Multi-Access User Plane (MX10004)—Starting in Junos OS Release 22.3R1, LC2101 and LC480 line cards support Junos Multi-Access User Plane functions.
