IPv6 Network Topology Scenario

The tasks throughout this chapter explain how to plan for IPv6 services on a typical enterprise network. The following figure shows the network that is referred to throughout the chapter. Your proposed IPv6 network might include some or all of the network links that are illustrated in this figure.

Figure 4-1 IPv6 Network Topology Scenario

image:The figure shows an IPv6 network. The next text describes the figure's contents.

The enterprise network scenario consists of five subnets with existing IPv4 addresses. The links of the network correspond directly to the administrative subnets. The four internal networks are shown with RFC 1918-style private IPv4 addresses, which is a common solution for the lack of IPv4 addresses. The addressing scheme of these internal networks follows:

The external, public network 172.16.85 functions as the corporation's DMZ. This network contains web servers, anonymous FTP servers, and other resources that the enterprise offers to the outside world. Router 2 runs a firewall and separates public network 172.16.85 from the internal backbone. On the other end of the DMZ, Router 1 runs a firewall and serves as the enterprise's boundary server.

In Figure 4-1, the public DMZ has the RFC 1918 private address 172.16.85. In the real world, the public DMZ must have a registered IPv4 address. Most IPv4 sites use a combination of public addresses and RFC 1918 private addresses. However, when you introduce IPv6, the concept of public addresses and private addresses changes. Because IPv6 has a much larger address space, you use public IPv6 addresses on both private networks and public networks.
