Configuring Dynamic VLAN Subscriber Interfaces Based on Agent Circuit Identifier Information

To configure a dynamic VLAN subscriber interface based on ACI information:

• In the dynamic profile for the PPPoE or IP demux subscriber interface, associate the dynamic ACI interface set with the dynamic VLAN subscriber interface name (pp0 or demux0) and logical unit number.

  [edit dynamic-profiles profile-name]
  user@host# set interfaces interface-set $junos-interface-set-name interface interface-name unit $junos-interface-unit
  

  For example, the following statement in a dynamic profile named aci-vlan-pppoe-profile associates the dynamic ACI interface set with the dynamic pp0 (PPPoE) logical subscriber interface. You must use the predefined dynamic variable $junos-interface-set-name to represent the name of the dynamic ACI interface set, and $junos-interface-unit to represent the logical unit number of the subscriber interface.

  content_copy zoom_out_map

  [edit dynamic-profiles aci-vlan-pppoe-profile]
  user@host# set interfaces interface-set $junos-interface-set-name interface pp0 unit $junos-interface-unit
  

  Similarly, the following statement in a dynamic profile named aci-vlan-demux-profile associates the dynamic ACI interface set (represented by $junos-interface-set-name) with the demux0 (IP demux) logical subscriber interface.

  content_copy zoom_out_map

  [edit dynamic-profiles aci-vlan-demux-profile]
  user@host# set interfaces interface-set $junos-interface-set-name interface demux0 unit $junos-interface-unit
  

The following examples show the dynamic configurations that use each of these statements. The following sample configuration shows a dynamic profile named aci-vlan-pppoe-profile for an ACI-based dynamic PPPoE (pp0) subscriber interface for use by PPPoE subscribers.

[edit dynamic-profiles aci-vlan-pppoe-profile]
interfaces {
    interface-set "$junos-interface-set-name" {
        interface pp0 {
            unit "$junos-interface-unit";
        }
    }
    pp0 {
        unit "$junos-interface-unit" {
            ppp-options {
                chap;
                pap;
            }
            pppoe-options {
                underlying-interface "$junos-underlying-interface";
                server;
            }
            no-keepalives;
            family inet {
                unnumbered-address lo0.0;
            }
        }
    }
}

The following sample configuration shows a dynamic profile named aci-vlan-demux-profile for an ACI-based dynamic IP demux(demux0) subscriber interface for use by DHCP subscribers.

[edit dynamic-profiles aci-vlan-demux-profile]
interfaces {
    interface-set "$junos-interface-set-name" {
        interface demux0 {
            unit "$junos-interface-unit";
        }
    }
    demux0 {
        unit "$junos-interface-unit" {
            demux-options {
                underlying-interface "$junos-underlying-interface";
            }
            family inet {
                demux-source {
                    $junos-subscriber-ip-address;
                }
                unnumbered-address lo0.0 preferred-source-address  198.51.100.202;
            }
        }
    }
}
