Description

Define the role of the routing instance in a Layer 2 Wholesale network.

Options

access—Defines the connectivity role of the routing instance in a Layer 2 Wholesale network as an access routing instance. When defined for this role, the same process occurs as in a Layer 3 Wholesale network—when the first packet is received from a given client, authentication for the client initiates with an external entity (for example, RADIUS). If authentication is successful, a logical interface is created with the appropriate outer and inner VLAN tags for that client.

nni—Defines the connectivity role of the routing instance in a Layer 2 Wholesale network as a network to network interface (NNI) routing instance. When defined for this role, only outer VLAN tags are learned. In addition, when the NNI routing instance receives a response from the ISP, the packets are forwarded to the appropriate client, provided the packet has the same two tags that were verified during authentication.

Note:

If you connect an access node or MSAN device to a router participating in the Layer 2 Wholesale network in an NNI role, you must create a new routing instance of type l2backhaul-vpn with an instance role of type access for that connection.

Required Privilege Level

routing—To view this statement in the configuration.

routing-control—To add this statement to the configuration.

Release Information

Statement introduced in Junos OS Release 11.2.
