Managing IP Networks with Cisco Routers
Routers are the glue that connects the pieces of your
network. Even in the simplest networks, this isn't a simple
task. Routers have evolved into highly specialized
computing platforms, with extremely flexible but complex
capabilities.
Managing IP Networks with Cisco Routers is a practical guide
to setting up and
maintaining a production network. It
discusses issues like how to select routing protocols and
how to configure protocols to handle most common situations.
It also discusses less esoteric but equally important issues
like how to evaluate network equipment and vendors and how
to set up a help desk. Although the book focuses on Cisco
routers, and gives examples using Cisco's IOS, the
principles discussed are common to all IP networks,
regardless of the vendor you choose.
This book is firmly grounded in the realities of day-to-day
network management. It's designed to solve real-world
problems, like: "How do I prevent my router from using
unreliable information from other routers?" "How do I
safeguard my router against attacks?" "How can I make my
network more reliable?" If you're building or maintaining
an IP network, you'll find this book indispensable.
Topics covered include:
Designing an IP network
Evaluating equipment and vendors
Selecting routing protocols
Configuring common interior protocols (RIP, OSPF, EIGRP)
Connecting to external networks and configuring exterior
protocols (BGP)
Ongoing network management: troubleshooting and maintenance
Security and privacy issues
