Introduction

This Part of the CDPD System Specification defines a protocol for the exchange of forwarding and routing information between home and serving Mobile Data Intermediate Systems (MD-ISs), and between home MD-ISs, for the support of Network Layer mobility.

This connectionless protocol operates over Connectionless Network Protocol (CLNP) [ISO-8473], and optionally operates over Internet Protocol (IP) [RFC791].

MNLP is designed to operate in conjunction with the Mobile Network Registration Protocol (MNRP), described in Part 507, and Radio Resource Management Protocol, described in Part 405, for providing Mobility Management services in the CDPD Network.

This protocol provides for the exchange of location and rediretion information between MD-ISs, as well as the forwarding and routing of messages to visiting M-ESs.
