Logical Assessment

To perform the logical assessment, determine the following:

• The protocols that are being routed

• The IP address assignment scheme

• The Novell IPX address assignment

• The AppleTalk address assignment

• Whether any access list is used to filter addresses or broadcasts

• The Layer 3 architecture

Figure 1-3 provides an example of a logical assessment. Here, the IP address subnet information is documented. The figure shows five Ethernet segments with 24-bit subnet masks that can support up to 254 nodes each. This figure also shows four point-to-point links with 30bit masks. With this mask, two IP addresses are used for each router on the link.
