The RIB is a table of • Destination network • Port to forward traffic through • Next hop information Figure 3-9 illustrates a network and corresponding routing tables. Figure 3-9 A Network and Routing Tables From router C’s perspective, there…

Note This section describes what the Spanning Tree Protocol accomplishes and why it is important. The operation of SPT is outside the scope of this book. A single switch might be useful in some situations, but to build a large network, you are going to need more than one. How do hosts communicate when there…
If A, B, D, and E are running IPv6, the Neighbor Discovery (ND) protocol is used to map physical interface addresses. One major difference between IPv4 and IPv6 is that IPv6 hosts do not assume every other host on the segment is using the same prefix. Figure 3-5 illustrates. Figure 3-5 IPv6 Neighbor Discovery Because…
on a Single Wire – Ciscco Certifed Support Technici Once all the hosts connected to a single segment have physical and interface addresses, they can begin to communicate. Figure 3-4 will be used to explain the process. Figure 3-4 Host-to-Host Communication In the figure, each of these hosts has two addresses: a physical address and…
