Abstract

A method of providing a path between bridges of a first network segment. The first network segment is configured using a Spanning Tree Protocol (‘STP’). The method includes providing a second network segment interconnecting first and second bridges of said first network segment. The second network segment is operable to transmit frames adherent to a High-availability Seamless Redundancy (‘HSR’) network control protocol and to discard the STP control data frames. The method also includes modifying at a first Redundancy Box (‘RedBox’) STP control data frames to form modified data frames adherent to the HSR protocol. The method also includes modifying at a second RedBox, the modified data frames to re-form the STP control data frames.
