Configuring a Stacked VLAN Dynamic Profile

• Configure the dynamic profile.

  See Configuring a Basic Dynamic Profile.

1. Ensure that the VLAN dynamic profile uses the $junos-interface-ifd-name variable for the dynamic interface and the $junos-interface-unit variable for the interface unit.
2. (Optional) To support dynamic demux interfaces, enable them using the demux-source statement.
   1. For IPv4 demux interfaces, specify inet as the source type.
      [edit dynamic-profiles VLAN-PROF1 interfaces "$junos-interface-ifd-name" unit "$junos-interface-unit"]user@host# set demux-source inet
   2. For IPv6 demux interfaces, specify inet6 as the source type.
      [edit dynamic-profiles VLAN-PROF1 interfaces "$junos-interface-ifd-name" unit "$junos-interface-unit"]user@host# set demux-source inet6
3. (Optional) To configure the router to respond to any ARP request, specify the proxy-arp statement.
   [edit dynamic-profiles VLAN-PROF1 interfaces "$junos-interface-ifd-name" unit "$junos-interface-unit"]user@host# set proxy-arp
4. Specify the outer VLAN ID variable.
   [edit dynamic-profiles STACKED-VLAN-PROF1 interfaces "$junos-interface-ifd-name" unit "$junos-interface-unit"]user@host# set vlan-tags outer $junos-stacked-vlan-id

   The variable is dynamically replaced with an outer VLAN ID within the VLAN range specified at the [interfaces] hierarchy level.

5. Specify the inner VLAN ID variable.
   [edit dynamic-profiles STACKED-VLAN-PROF1 interfaces "$junos-interface-ifd-name" unit "$junos-interface-unit"]user@host# set vlan-tags inner $junos-vlan-id

   The variable is dynamically replaced with an inner VLAN ID within the VLAN range specified at the [interfaces] hierarchy level.

6. Define the unit family type.
   1. For IPv4 interfaces, specify the inet family type.
      [edit dynamic-profiles VLAN-PROF1 interfaces "$junos-interface-ifd-name" unit "$junos-interface-unit"]user@host# set family inet
   2. For IPv6 interfaces, specify the inet6 family type.
      [edit dynamic-profiles VLAN-PROF1 interfaces "$junos-interface-ifd-name" unit "$junos-interface-unit"]user@host# set family inet6
7. (Optional) Enable IP and MAC address validation for dynamic demux interfaces in a dynamic profile.
   [edit dynamic-profiles VLAN-PROF1 interfaces "$junos-interface-ifd-name" unit "$junos-interface-unit" family inet]user@host# set mac-validate loose
8. Specify the unnumbered address and preferred source address.
   [edit dynamic-profiles VLAN-PROF1 interfaces "$junos-interface-ifd-name" unit "$junos-interface-unit" family inet]user@host# set unnumbered-address lo.0 preferred-source-address 192.0.16.1
