The previous book in this series, The Packet Guide to Core Network Protocols, covered
the IPv4 protocols, masking, and devices that are part of every network. Now it’s time
to take on the routing and switching for the network. There are an astonishing number
of table-based decisions that have to be made in order to get a single packet across a
network, let alone across a series of networks. Not limited to routers, switches, and
access points, these decisions are made at each and every device, including hosts. As
networks are constructed and devices configured to forward packets and frames, network
administrators must make critical decisions affecting performance, security, and
optimization.
When moving to advanced ideas, the net admin should know how and why networking
tables are constructed, and in what cases manual changes will be beneficial. This chapter
provides details about the routing and switching operations, as well as design elements.
This chapter assumes that the reader understands the basic operation of routers
and switches, as well as the standard suite of protocols including Ethernet, Internet
Protocol (IP), Address Resolution Protocol (ARP), and the Internet Control Message
Protocol (ICMP).
