(This book discusses how to configure Cisco routers for bridging, DLSw+, and desktop protocols. The book is organized into three parts. Some of the top ones start with the basic transparent bridging configuration, and on the basis of completing the transparent bridging based on Frame Relay, X.25 and DDR, the source route bridging on Token Ring and the transparent bridging on Ethernet are completed; the second is complete. The concept and completion of DLSw+ are introduced; third, the concept and configuration of desktop protocols such as NovellIPX, AppleTalk, BanyanVINES, DECnet and ISOCLNS are commented in detail. This book has introduced a lot of technical details in an easy-to-understand way through various examples, and readers do not need to have the knowledge of profound IBM network or desktop protocols. This book is suitable for candidates preparing for the CCIE certification exam, or network experts who need to configure Cisco routers to support multi-protocol networks.)
