Query: Excellent multi-protocol book

These authors know how to write technical literature that did not confuse me!Our company uses IPX and Appletalk for various departments although we are moving with haste to an all IP shop. I found this book to help me with building a multiprotocol network and to better understand the details of IP routing. The book covered IP routing in depth and covered enough of IPX and Appletalk to help me optimize my network. I found the example network with the full IOS configuration files quite useful.
