1.0 Classical IP over ATM (CLIP)
1.1 Introduction
Classical IP over ATM was defined by the IETF in January 1994. The specification RFC 1577 for transmitting IP datagrams and ATM Address Resolution Protocol (ATMARP) requests over ATM Adaptation Layer 5 (AAL5) [RFC 1577]. The term

1.0 Introduction
With the CLIP, (as mentioned before), inter-LIS communications have to go through routers. This is not an optimal solution when both nodes communicate with each other are attached to the same ATM network. A mechanism is needed for an end system to resolve the IP address of another end system in a foreign LIS into the corresponding ATM address. The NBMA (Non Broadcast, Multi Access) NHRP protocol, developed by the IETF, overcomes this limitation and provides this mechanism.
