202 Implementing IBM System Networking 10Gb Ethernet Switches
For our reference architecture, we use static IPv6 configuration. For a static IPv4 and
IPv6 configuration example, see Figure 5-9.

This section describes OSPF dynamic routing protocol implementation in switches using the
reference architecture in Chapter 3, “Reference architectures” on page 107. It does not
provide a complex configuration, as you would expect in an enterprise or service provider
production network. It shows basic configuration steps only, as a starting point for enabling
OSPF-based dynamic routing in the network for both IPv4 and IPv6 protocols, using IBM
System Networking RackSwitches switches running IBM Networking OS.
Not all the features of OSPF protocol implemented in IBM Networking OS are covered in this
section. For more detailed configuration options and commands, see 5.5, “More information”
on page 238.
Our goal is to have a basic dynamic routing mechanism that runs on IPv4 and IPv6 at the
same time, using the same infrastructure, without a significant configuration effort. For
OSPFv3, you need IPv6 addresses, but restrictions apply when configuring IPv4 and IPv6
interfaces in IBM Networking OS.
Important: This method is the only method for configuring IP addresses and IP
routes on Linux. This configuration is also a temporary configuration that is
discarded at reboot. For a permanent IP configuration in Linux, see the appropriate
Red Hat Linux documentation.
