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. For a gateway-half pair, include the link name.)
2. Complete the tables: two for each network, one for each
gateway-half pair.
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.

LAN Network Table.
Refer to the LAN network map to fill in the LAN network table (table
3-2). The first column lists the names of all the nodes on NET1. Each
node is assigned an IP address that is unique within the network. Only
the node portion of the IP address is listed since the IP network address
is noted at the top of the table. In the third column of table 3-2, node
B is shown as a proxy server. The fourth column lists node B as a
gateway node. In the Implementation Priority column, the nodes are
ranked in the recommended order of configuration.

LAN Internet Routing Table.
The purpose of the LAN internet routing table (table 3-3) is to list all
possible networks that can be reached from each gateway node on a LAN,
such as NET1 in the example.
As shown on the internetwork map, NET1 includes a gateway node, node B.
In the IP Node Address column of the LAN internet routing table, the node
portion of the gateway node's IP address is listed. The LAN internet
routing table shows that NET1 nodes using node B as a gateway can reach
NET2 in one hop, NET5 in two hops, and NET3 in three hops. Node B is
also designated as a default gateway.

Token Ring Network Worksheets
You may use the worksheets found in the LAN section for token ring. It
is important to note that token ring does not use a proxy server.
FDDI Network Worksheets
You may use the worksheets found in the LAN section for FDDI as well. It
is important to note that FDDI does not use a proxy server.
Point-to-Point Network Worksheets
One set of point-to-point network worksheets should be used for each
point-to-point network in your internetwork. These network worksheets
consist of a map of the point-to-point network and two tables. One table
contains information about each node on the network and one table
contains network-specific internet routing information.
Point-to-Point Network Map.
NET2 is the point-to-point network in the sample internetwork. Figure
3-3 is a drawing of the network map for NET2. 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. This information is
derived from the internetwork map.
The internetwork map shows that nodes B and G are gateway nodes and also
shows the networks that the gateway nodes can reach. The remaining NET2
nodes and their names are added to the network map. Node G is a central
administrative node.

Point-to-Point Network Table.
Refer to the point-to-point network map to fill in the point-to-point
network table (table 3-4). We have completed the first column by listing
the names of all the nodes on NET2. Each node is assigned an IP address
that is unique within the network. Only the node portions of the IP
addresses are listed because we have listed the IP network address at the
top of the table. In the third column of table 3-4, note that node G is
a central administrative node. In the fourth column, nodes B and G are
indicated as gateway nodes. For the Implementation Priority column, the
nodes are ranked in the recommended order of configuration.

Point-to-Point Internet Routing Table.
The purpose of the point-to-point internet routing table (table 3-5) is
to list all possible networks that can be reached from each gateway node
on a point-to-point network, which is NET2 in the example. (Note that
there may be more than one route to a network.)
As shown on the internetwork map, NET2 includes two gateway nodes, B and
G. In the IP Node Address column of the point-to-point internet routing
table, the node portion of each gateway node's IP address is listed. The
point-to-point internet routing table indicates that NET2 nodes using
node B as a gateway can reach NET1 in one hop, NET4 in two hops, and so
on.
For Node G, the same type of information is listed.

X.25 Network Worksheets
One set of X.25 network worksheets should be used for each X.25 network
in your internetwork. The X.25 worksheets consist of a map of the X.25
network and two tables. One table contains information about each node
on the X.25 network. The other table contains network-specific internet
routing information.
X.25 Network Map.
Figure 3-4 is a drawing of the network map for NET3. The network map is
a detailed drawing of the same network shown in the internetwork map
(figure 3-1). The network name, the IP address, and the network type are
shown on the network map. This information is derived from the
internetwork map.
In the example, node B of NET1 and nodes H and I of NET5 are also part of
the X.25 network. The remaining NET3 nodes and their names are added to
the network map. The network map also shows node H as a central
administrative node.

Figure 3-4. X.25 Network Map
X.25 Network Table.
Refer to the X.25 network map to fill in the X.25 network table. We
complete the first column by listing the names of all the nodes on NET3.
Each node is assigned an IP address that is unique within the network.
Only the node portions of the IP addresses are listed since the IP
network address is listed at the top of the table. In the third column
of the table, node H is indicated as a central administrative node. The
X.25 (subnet) address for each node is listed in the fifth column of the
network table. The X.25 address is a decimal number (up to 15 digits)
identifying a node's location on the X.25 subnet for connections using
switched virtual circuits (SVCs). Usually this address is inserted in
CALL packets to set up connections using SVCs. If the network you will
access is a public packet switching network (PSN), these addresses (where
appropriate) are recorded on the network subscription form.

X.25 Internet Routing Table.
The purpose of the X.25 internet routing table is to list the other
networks in the internetwork that can be reached from the X.25 network,
which is NET3 in the example. (Note that there may be more than one
route to a network.)
As shown in the internetwork map (figure 3-4), NET3 includes two gateway
nodes, B and H. In the X.25 internet routing table note that NET3 nodes
using Node H can reach NET5 in one hop, NET2 in two hops, and so on. In
the IP Node Address column, the node portion of the node's IP address is
listed.

Gateway Half Pair Worksheets
One set of gateway half pair worksheets should be used for each gateway
half pair in your internetwork. The gateway half pair worksheets consist
of a map of the two gateway half nodes and their connecting link, and one
table that contains information about the gateway half network
interfaces. In the sample internetwork shown in figure 3-1, nodes G and
H form a gateway half pair. Use the discussion of the sample gateway
half pair worksheets as a guide for filling out your own gateway half
pair worksheets.
Gateway Half Map.
The sample internetwork contains one gateway half pair, as shown in the
internetwork map, which is made up of nodes G and H and their connecting
link. Figure 3-5 is a drawing of the gateway half pair showing the two
nodes and the networks to which they belong. In addition, the map shows
the link name, LINKRL1.
