An optimized interface for handling routed and non-routed point-to-point sessions is provided. According to one exemplary aspect, when a PPP session is established for a client, an interface data structure or module is dynamically created for the client corresponding to the PPP session. The interface data structure includes, for example, Layer-2 and Layer-3 information relating to the PPP session. Upon its creation, the interface data structure is linked to the optimized interface. The created interface data structure is then used by the optimized interface to facilitate communications with the client for the duration of the PPP session.
