L2BSA Configuration

This document assumes a working base configuration explaining the L2BSA specific additions only.

AAA Profile Configuration

Each L2BSA service refers to a mandatory AAA configuration profile as explained in detail in the Subscriber Management Configuration Guide. The following example shows the minimum configuration with authentication and accounting disabled.

supervisor@leaf1: cfg> show config access aaa-profile aaa-l2bsa-default
{
    "rtbrick-config:aaa-profile": [
      {
        "profile-name": "aaa-l2bsa-default",
        "authentication": {
          "order": "NONE"
        },
        "accounting": {
          "order": "NONE"
        }
      }
    ]
  }

Intermediate Agent Configuration

The intermediate agent function must be enabled for each physical interface used by L2BSA services.

supervisor@leaf1: cfg> set access l2bsa intermediate-agent interface ifp-0/1/23
  <cr>
  pppoe-enable          Enable/disable the L2BSA intermediate agent for PPPoE Discovery
  dhcpv4-enable         Enable/disable the L2BSA intermediate agent for DHCPv4
  dhcpv6-enable         Enable/disable the L2BSA intermediate agent for DHCPv6
  vlan-mode             L2BSA intermediate agent VLAN mode
  inner-vlan-min        Inner VLAN min
  inner-vlan-max        Inner VLAN max
Attribute Description

pppoe-enable

This option allows enabling/disabling the intermediate agent function for PPPoE discovery packets.

Default: true (enabled)

dhcpv4-enable

This option allows enabling/disabling the intermediate agent function for DHCPv4 packets.

Default: true (enabled)

dhcpv6-enable

This option allows enabling/disabling the intermediate agent function for DHCPv6 packets.

Default: true (enabled)

vlan-mode

This option enables the intermediate agent function for single, double or single and double-tagged packets.

Default: SINGLE_DOUBLE Values: SINGLE, DOUBLE, SINGLE_DOUBLE

inner-vlan-min/max

This option is applicable for double-tagged packets only and allows limiting the intermediate agent function to a given inner VLAN range.

Default: all

The following common example enables the intermediate agent for all packets (PPPoE, DHCPv4 and DHCPv6) for all single-tagged packets and double-tagged packets with inner VLAN between 1 and 3000.

supervisor@leaf1: cfg> show config access l2bsa intermediate-agent
{
    "rtbrick-config:intermediate-agent": {
      "interface": [
        {
          "interface-name": "ifp-0/1/23",
          "inner-vlan-min": 1,
          "inner-vlan-max": 3000,
        }
      ]
    }
  }
