Configuring a Layer 2 VPN Routing Instance on a VLAN-Bundled Logical Interface

To configure a VLAN-bundled logical interface, specify the list of VLAN IDs by including the vlan-id-list statement or the vlan-tags statement on a provider edge (PE) router:

interfaces {
    ethernet-interface-name {
        vlan-tagging; # Support single- or dual-tag logical interfaces 
        flexible-vlan-tagging; # Support mixed tagging
        encapsulation (extended-vlan-ccc | flexible-ethernet-services);
        unit logical-unit-number {
            vlan-id-list [vlan-id vlan-id–vlan-id]; # For single-tag
            vlan-tags outer <tpid.>vlan-id inner-list [vlan-id vlan-id–vlan-id]; # For dual-tag
        }
        . . .
    }
}

You can include the statements at the following hierarchy levels:

• [edit]

• [edit logical-systems logical-system-name]

To configure a Layer 2 VPN routing instance on a PE router, include the instance-type statement and specify the value l2vpn. To specify an interface connected to the router, include the interface statement and specify the VLAN-bundled logical interface:

instance-type l2vpn;
interface logical-interface-name;

You can include the statements at the following hierarchy levels:

• [edit routing-instances routing-instance-name]

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

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 OS VPNs Library for Routing Devices.

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.
