Autosensing LMI protocols in frame relay networks
First Claim
1. A method of configuring a router and a frame relay network switch to use a selected LMI protocol in a frame relay network, said method comprising transmitting substantially simultaneously a plurality of requests, one for each of a set of LMI protocols, from said router to said frame relay network switch;
- receiving at least one said request at said frame relay network switch, configuring said frame relay network switch in response to said request, and transmitting a response thereto;
receiving said response at said router and configuring said router in response thereto.

Abstract
The invention provides a method and system for auto-sensing LMI protocols in frame relay networks. When a router is first coupled to a frame relay network, it automatically configures the local management interface (LMI) to use one of a selected set of possible LMI protocols, by generating a set of protocol requests for a plurality of protocols, and by thereafter simultaneously listening for protocol responses from the configuration server. Multiple valid responses from the configuration server are assigned priority in response to which valid response is last to arrive.
