Configuring a VLAN Dynamic Profile for Creating Single-Tag VLANs Using Standard TPID Values

You can configure a VLAN dynamic profile to create single-tag VLANs that accept only standard TPID values (a TPID value of 0x8100) by using the vlan-id statement and the $junos-vlan-id variable.

Note: This procedure configures a dynamic profile that accepts only TPID values of 0x8100. To configure a VLAN dynamic profile for creating VLANs using any TPID values, see Configuring a VLAN Dynamic Profile for Creating Single-Tag VLANs Using Any TPID Values.

• 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 "$junos-interface-unit"]user@host# set proxy-arp
4. Specify that you want to use dynamic VLAN IDs in the dynamic profile.
   [edit dynamic-profiles VLAN-PROF1 interfaces "$junos-interface-ifd-name" unit "$junos-interface-unit"]user@host# set vlan-id $junos-vlan-id

   When the dynamic profile is instantiated, the variable is dynamically replaced with a VLAN ID within the VLAN range specified at the [interfaces] hierarchy level.

5. 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
6. (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
7. 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
