Install IPv6-Capable Routers
Install IPv6-Capable Routers
This process depends on the hardware vendor you have chosen. You must define
what address prefixes the router will advertise and the interfaces over which to
advertise them.
Configure NonStop Server IPv6 Hosts
1. Decide if you want to run in INET6 mode. You might use this mode if you are
running IPv6 in a network that is restricted to IPv6. See Configure the Basic
Subsystem for INET6 Mode on page 5-7.
2. Decide if you want to run in DUAL mode. This mode lets you communicate with the
broader network because this mode functions with the IPv4-prevalent network.
Section 1, Quick Start shows you how to configure the subsystem for DUAL mode.
3. Decide if you want this system to update the DNS database automatically; if so,
you must also provide a fully-qualified domain name for the IPv6 host. In addition,
you must configure the ND6HOSTD process. See Configure the ND6HOSTD
Process for Address Resolution on page 6-19.
4. Decide if you need a configured IPv4 tunnel for communications with other IPv6
nodes or networks. If so, you need to run in DUAL mode (see Section 1, Quick
Start) and you need the remote node's IPv4 address (the remote end of the tunnel)
as well as your own node's IPv4 address (local end of the tunnel). See Configure
the Subsystem for DUAL-Mode, Address Autoconfiguration and Configured
Tunneling on page 1-18.
5. Decide if you want to configure static routes. You might want to configure static
routes if you want a configured tunnel to a router and the router is not advertising.
See Add Routes on page 5-6 for information about adding static routes.
6. Decide if you need to isolate applications to specific IP addresses. For information
about limiting which IP addresses an application listens on in the NonStop
TCP/IPv6 architecture, see Logical-Network Partitioning (LNP) on page 2-7.
7. Decide if you want to use NonStop TCP/IPv6 to create high-capacity networking
applications. For information about using this feature in addition to all of Section 3,
Maximize the Benefit of the NonStop TCP/IPv6 Architecture to understand how to
scale your applications, see Round-Robin Filtering on page 2-6.
Develop an IPv6 Implementation Plan
This subsection provides three scenarios of ways to gradually implement IPv6 in your
environment. The scenarios, in order of increasing complexity are:

Note. Also, configure the DNS server to allow dynamic updates.
