Event ID 20181 — RRAS Routing Interfaces

  • Article

Applies To: Windows Server 2008

The server running Routing and Remote Access uses a routing interface to forward unicast IP and multicast IP packets. There are two types of routing interfaces: LAN interfaces and demand-dial interfaces. A LAN interface is a physical interface that typically represents a local area connection that uses local area networking technology such as Ethernet or token ring. A demand-dial interface is a logical interface that represents a point-to-point connection. The point-to-point connection is based on either a physical connection, such as two routers connected over an analog phone line that uses modems, or a logical connection, such as two routers connected over a virtual private network (VPN) connection that uses the Internet.
