Planning Your Network
Network Worksheets
Network Worksheets
For each network in your internetwork, you are asked to draw a map of
the network and to complete two tables. One table lists node-specific
information, and one table lists network routing information.
You also are asked to complete worksheets for each gateway half pair in
your internetwork. The worksheets for a gateway half pair consist of a
map of the gateway half nodes and their connecting link and a table
containing information about the gateway half network interfaces.
In the sample internetwork shown in Figure 3-1, six sets of network
worksheets need to be completed: one set for each of the six networks
and one set for the gateway half pair.
Take the following steps when filling out a set of network worksheets:
1. Draw your map, showing all nodes and node names. For
Point-to-Point networks, also show all Point-to-Point links and link
names.
2. Complete the two tables: for each network, for a gateway-half pair,
include the link name.
LAN Network Worksheets
One set of LAN network worksheets should be used for each LAN in
your internetwork. The LAN network worksheets consist of a map of
the LAN and two tables. One table contains information about each
node on the LAN and one table contains network-specific internet
routing information.
In this example, we have shown the network map and worksheet for
NET1, one of the LAN networks shown in Figure 3-1. Use the
discussion of the sample LAN network worksheets as a guide for filling
out your own LAN network worksheets.
LAN Network Map
Figure 3-2 is a drawing of the network map for NET1. The network map
is a detailed drawing of the same network shown in the internetwork
map (Figure 3-1). The network name, the IP network address, and the
network type are listed at the top of the network map.
In the example, the internetwork map shows that node B is a gateway
node. It is noted on the NET1 network map and shows the network that
the gateway node can reach. Node B is also a proxy server. The
remaining NET1 nodes and their names are added to the network map.
