IPv6 Network Topology Scenario

Typically, IPv6 is used in a mixed network topology that also uses IPv4, such as shown in the following figure. This figure is used as reference in the description of IPv6 configuration tasks in the subsequent sections.

Figure 2-1 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 2-1, 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.

The Oracle Solaris dual protocol stack supports concurrent IPv4 and IPv6 operations. You can successfully run IPv4–related operations during and after deployment of IPv6 on your network. When you deploy IPv6 on an operating network that is already using IPv4, ensure that you do not disrupt ongoing operations.

The following sections describe areas that you need to consider when preparing to implement IPv6.
