Configuring Encapsulation for Layer 2 Wholesale VLAN Interfaces

Each dynamic VLAN interface in a Layer 2 wholesale network must use encapsulation. You can configure encapsulation dynamically for each VLAN interface by using the encapsulation statement at the [edit dynamic-profiles profile-name interface “$junos-interface-ifd-name” unit “$junos-interface-unit”] hierarchy level or configure encapsulation for the physical interfaces at the [edit interfaces interface-name] hierarchy level for each dynamically created VLAN interface to use. However, how you choose to configure (or not configure) encapsulation at the [edit dynamic-profiles profile-name interface “$junos-interface-ifd-name” unit “$junos-interface-unit”] hierarchy level affects how you configure encapsulation at the [edit interfaces interface-name] hierarchy level.

Table 1 provides the valid encapsulation combinations for both dynamic profiles and physical interfaces in the Layer 2 wholesale network.

Usage Notes

vlan-vpls

vlan-vpls

Using the vlan-vpls encapsulation type in both the dynamic profile and when configuring the physical interface limits the VLAN ID value to a number greater than or equal to 512.

vlan-vpls

flexible-ethernet-services

Using the flexible-ethernet-services encapsulation type removes any VLAN ID value limitation.

vlan-vpls

extended-vlan-vpls

The extended-vlan-vpls encapsulation type can support multiple TPIDs. Using this encapsulation type removes any VLAN ID value limitation.

No encapsulation type

extended-vlan-vpls

The extended-vlan-vpls encapsulation type can support multiple TPIDs. Using this encapsulation type removes any VLAN ID value limitation.

To configure encapsulation for Layer 2 wholesale VLAN interfaces:

  1. (Optional) Define the VLAN encapsulation for the dynamic interfaces.
  2. Specify the encapsulation type for the physical VLAN interface.
    Note:

    If you choose not to specify an encapsulation for the logical interface, you must specify extended-vlan-vpls encapsulation for the physical interface.
