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

When connecting a subscriber access router directly to an ISP access router, you must define any ISP-facing interfaces that connect to the retailer ISP access routers as core-facing interfaces.

To configure a direct 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. Specify the unit family.
  5. Define the interface as core-facing to ensure that the network does not improperly treat the interface as a client interface..
  6. Repeat steps for any other direct ISP-facing interfaces that you want to use..
