Specifying the Interface to Handle Traffic for a CCC

To configure the VLAN-bundled logical interface as the interface to handle traffic for a circuit connected to the Layer 2 VPN routing instance, include the following statements:

protocols {l2vpn {(control-word | no-control-word);encapsulation-type (ethernet | ethernet-vlan); site site-name {site-identifier identifier;interface logical-interface-name { # VLAN-bundled logical interface. . . interface-options . . .}}}}

You can include the statements at the same hierarchy level at which you include the instance-type l2vpn and interface logical-interface-name statements:

  • [edit routing-instances routing-instance-name]
  • [edit logical-systems logical-system-name routing-instances routing-instance-name]

To enable a Layer 2 VPN routing instance on a PE router, include the l2vpn statement. For more information, see the JUNOS VPNs Configuration Guide.

The encapsulation-type statement specifies the Layer 2 protocol used for traffic from the customer edge (CE) router. If the Layer 2 VPN routing instance is being connected to a single-tag Layer 2 circuit, specify ethernet as the encapsulation type. If the Layer 2 VPN routing instance is being connected to a dual-tag Layer 2 circuit, specify ethernet-vlan as the encapsulation type.

To specify the interface to handle traffic for a circuit connected to the Layer 2 VPN routing instance, include the interface statement and specify the VLAN-bundled logical interface.
