    Are you planning on taking the CCNA Routing and Switching exam?

    Are you planning on taking the CCNA Routing and Switching exam? If you are, then this book is for you! Author Scott Empson, has done an outstanding job of writing a 3rd edition of a book which closely aligns with industry’s need for networking talent, as you enter into the era of the Internet of Everything.




    Author Empson, begins with an overview of how to subnet. Then, the author provides an overview of VLSM by showing examples of how to use VLSM to make your IP plan more efficient. He continues by showing you how to use route summarization to make your routing updates more efficient. Then, the author shows you how to connect to Cisco devices. He then shows you how to navigate through Cisco IOS Software. Next, the author shows you how to configure commands to a single router. The author continues by showing you how to configure static routes in your internetwork. Then, he shows you how to configure and verify EIGRP. Next, the author shows you how to configure and verify single-area and multi-area OSPF. He also shows you how to configure commands for Catalyst 2960 switches. The author continues by showing you how to configure VLANs. Then, he shows you how to configure a VLAN trunk link The author then, shows you how to verify STP. Next, he shows you how to configure HSRP. The author continues by showing you how to transition to IPv6. Then, he shows you how to configure OSPF and EIGRP to work with IPv6. Next, the author shows you how to use boot commands for Cisco IOS Software. The author continues by showing you how to configure the register. Then, he shows you how to customize and verify CDP. Next, the author shows you how to use the commands for Telnet and SSH to remotely connect other devices. The author continues by showing you how to use the commands for both ping and extended ping. Then, he shows you how to configure SNMP. Next, the author shows you how to use the various show commands to view the routing table. The author then, discusses the differences between licensing pre- and post-Cisco IOS Version 15. He also shows you how to configure and verify NAT and PAT. The author continues by showing you how to configure and verify DHCP on a Cisco IOS router. Then, he shows you how to configure PPP. Next, the author shows you how to configure basic Frame Relay, Frame Relay and subinterfaces. He also shows you how to configure and verify GRE tunnels. The author continues by showing you how to configure a DSL connection using PPPoE. Finally, he shows you how to configure standard ACLs.




    This most excellent book makes use of RFC 1918 addressing throughout. In fact, this great book follows what the author thinks is a logical approach to configuring a small to mid-size network
