Multiprotocol Interconnect over Frame Relay

1. Status of this Memo

This RFC specifies an IAB standards track protocol for the Internet

community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "IAB Official Protocol

Standards" for the standardization state and status of this protocol. Distribution of this memo is unlimited.

2. Abstract

This memo describes an encapsulation method for carrying network

interconnect traffic over a Frame Relay backbone. It covers aspects of both Bridging and Routing. Systems with the ability to transfer

both this encapsulation method, and others must have a priori

knowledge of which virtual circuits will carry which encapsulation

method and this encapsulation must only be used over virtual circuits that have been explicitly configured for its use.
