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.
