Access Protocols

A BNG, or Broadband Network Gateway, is a network device that connects customer premises equipment to the service provider’s broadband network, managing user authentication, traffic routing, and quality of service (QoS) for internet services.

The BNG Blaster is equipped with versatile support for various access protocols, allowing the creation of seubscriber sessions, each of which can comprise multiple protocols. For instance, in the case of dual-stack IPoE sessions, these are formed by a combination of DHCPv4, DHCPv6, as well as ARP/ND protocols. Every session is defined by an access interface function and identified by a globally unique session-id, with the numbering starting at 1 and increasing sequentially for each new session established. Furthermore, you have the flexibility to group multiple sessions together using the optional session-group-id, which enables the application of commands commands to an entire group of sessions simultaneously.

{
    "access": [
        {
            "interface": "eth1",
            "type": "pppoe",
            "session-group-id": 1,
            "username": "even@rtbrick.com",
            "outer-vlan-min": 1000,
            "outer-vlan-max": 1998,
            "outer-vlan-step": 2,
            "inner-vlan": 7
        },
        {
            "interface": "eth1",
            "type": "pppoe",
            "session-group-id": 2,
            "username": "odd@rtbrick.com",
            "outer-vlan-min": 1001,
            "outer-vlan-max": 1999,
            "outer-vlan-step": 2,
            "inner-vlan": 7
        },
    ]
}

It is also possible to assign multiple access interface sections to a single session group.
