IPoE

The BNG Blaster is able to emulate IP over Ethernet (IPoE) subscribers with static and dynamic address assignment supporting 1:1 and N:1 VLAN mode.

Static Addresses

Static addresses means that the IP address and gateway is assigned statically as shown in the example below.

{
    "interfaces": {
        "access": [
        {
            "interface": "eth1",
            "type": "ipoe",
            "vlan-mode": "1:1",
            "outer-vlan-min": 128,
            "outer-vlan-max": 4000,
            "address": "200.0.0.1",
            "address-iter": "0.0.0.4",
            "gateway": "200.0.0.2",
            "gateway-iter": "0.0.0.4",
        }
    ]
    }
}

DHCPv4/v6

The most common case for IPoE is using DHCPv4/v6 as shown below.

{
    "interfaces": {
        "access": [
        {
            "interface": "eth1",
            "type": "ipoe",
            "outer-vlan": 7,
            "vlan-mode": "N:1"
        }
    ]
    },
    "dhcp": {
        "enable": true,
    },
    "dhcpv6": {
        "enable": true
    },
    "access-line": {
        "agent-remote-id": "DEU.RTBRICK.{session-global}",
        "agent-circuit-id": "0.0.0.0/0.0.0.0 eth 0:{session-global}"
    }
}

IPoE

{ "ipoe": {} }

Attribute	Description	Default
ipv4	Enable/disable IPv4	true (enabled)
arp-timeout	Initial ARP resolve timeout/retry interval in seconds	1
arp-interval	Periodic ARP interval in seconds (0 means disabled)	300
ipv6	Enable/disable IPv6	true (enabled)

DHCP

{ "dhcp": {} }

Attribute	Description	Default
enable	This option allows to enable or disable DHCP	false
broadcast	DHCP broadcast flag	false
timeout	DHCP timeout in seconds	5
retry	DHCP retry	10
release-interval	DHCP release interval	1
release-retry	DHCP release retry	3
tos	IPv4 TOS for all DHCP control traffic	0
vlan-priority	VLAN PBIT for all DHCP control traffic	0

DHCPv6

{ "dhcpv6": {} }

Attribute	Description	Default
enable	This option allows to enable or disable DHCPv6	true
rapid-commit	DHCPv6 rapid commit (2 way handshake)	true
timeout	DHCPv6 timeout in seconds	5
retry	DHCPv6 retry	10

IPoE Commands

The command session-info session-id <id> provides detailed information for IPoE sessions.

$ sudo bngblaster-cli run.sock session-info session-id 1 | jq .
