About this class

Cisco routers are a central component of many complex internetworks. Therefore, it is critical that networking professionals have detailed knowledge of advanced configuration options in order to achieve scalable router deployment and optimise network performance.

In this course, you gain the knowledge and skills required to master the advanced features of Cisco router configuration.

Who will the lesson benefit?

This course is valuable for network managers, engineers, technicians, designers and consultants who are involved in designing and implementing internetworks with Cisco routers. Knowledge of router configuration at the level of Course 466, " Cisco Networking Introduction ", is assumed.

What delegates will learn

• Optimise Cisco router configuration for large and complex IP internetworks
• Manage IP information flows with Cisco routers
• Deploy scalable routing protocols: EIGRP, OSPF and BGP
• Minimise core routing tables with route summarisation
• Map between private and public addresses with Network Address Translation (NAT)
• Strengthen network security with Cisco access lists
