access circuit (FR, ATM, PPP) with routed PDU IPv4 encapsulation and a host attached to an
Ethernet interface. Both hosts appear to be on the same LAN segment. This feature enables service
interworking between different link layer technologies. A typical use of this application is in a
Layer 2 VPN when upgrading a hub site to Ethernet while keeping the spoke sites with their
existing Frame Relay or ATM IPv4 routed encapsulation.
The ATM SAP carries the IPv4 packet using RFC 2684, Multiprotocol Encapsulation over ATM
Adaptation Layer 5
makes use of RFC 2427, Multiprotocol Interconnect over Frame Relay, routed PDU encapsulation
