Background / Scenario
Summary routes reduce the number of
entries in routing tables and make the routing table lookup process more efficient.
This process also reduces the memory requirements for the router. A single
static route can be used to represent a few routes or thousands of routes.
In this lab, you will determine the
summary routes for different subnets of a network. You will then determine the
summary route for the entire network. Summary routes will be determined for
both IPv4 and IPv6 addresses. Because IPv6 uses hexadecimal (hex) values, you
will be required to convert hex to binary.
Required Resources
·
1 PC (Windows 7, Vista, or XP
with Internet access)
·
Optional: calculator for
converting hex and decimal to binary
