Configuring NNI ISP-Facing Interfaces for the Layer 2 Wholesale Solution

You must configure separate, ISP-facing interfaces on each NNI ISP-facing router that connect to individual retailer ISP access routers in the Layer 2 Wholesale solution.

Note:

On the network-to-network (NNI) or egress interfaces of provider edge (PE) routers, you cannot configure the inner-range vid1—vid2 option with the vlan-tags statement for ISP-facing interfaces.

To configure an NNI ISP-facing interface:

  1. Access the physical interface that you want to use to access the retailer ISP network.
  2. Specify the encapsulation type for the VLAN interfaces.
  3. Specify the interface unit that you want ISP clients to use.
  4. Repeat these steps for any other NNI ISP-facing interfaces that you want to use. In this example, you must also configure interface ge-2/2/0.0.
