Chapter 5. IBM System Networking RackSwitch implementation 203
The solution for using the same layout for both IP protocols is to have pairs of IPv4 and IPv6
interfaces mapped to the same VLAN.
Figure 5-10 shows the reference architecture diagram used for OSPF implementation. The
two servers are Layer 2 connected to the core network. AGG-1, AGG-2, ACC-1, and ACC-2
are interconnected with point-to-point Layer 3 links. No VLAN spans
the network.

Note: The following guidelines and limitations apply when configuring IPv4 and IPv6
interfaces:
򐂰 You cannot configure an IPv4 address on an IPv6 interface. Each interface can be
configured with only one address type, either IPv4 or IPv6, but not both.
򐂰 Each IPv6 interface can belong to only one VLAN.
򐂰 Each VLAN can support only one IPv6 interface.
򐂰 Each VLAN can support multiple IPv4 interfaces.
