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.
Table 1: Encapsulation Combinations for Layer 2 Wholesale Interfaces
Dynamic Profile | Physical Interface |
|
|---|---|---|
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:
- (Optional) Define the VLAN encapsulation for the dynamic
interfaces.[edit dynamic-profiles Subscriber_Profile_Retail1 interfaces “$junos-interface-ifd-name” unit “$junos-interface-unit”]user@host# set encapsulation encapsulation-type
- Specify the encapsulation type for the physical VLAN interface.[edit interfaces ge-2/3/0]user@host# edit encapsulation encapsulation-type
Note: If you choose not to specify an encapsulation for the logical interface, you must specify extended-vlan-vpls encapsulation for the physical interface.
