Both default gateways (IPv4 and IPv6) are reachable, as shown in Figure 5-6.

– Configure Linux hosts.
For the Embedded switch reference architecture (see Chapter 6, “IBM Virtual Fabric
10Gb Switch Module implementation” on page 239), we used a blade server that runs
the Red Hat Enterprise Linux operating system connected internally to the two 10GbE
Virtual Fabric Switches in the Blade Center chassis.
The blade server is installed in slot 14 and has internal ports 1:14 and 2:14 in the
embedded switch.
Both 10 GbE interfaces of the server are configured in active-backup bonding. The IP
configuration is applied on the bond1 interface, aggregating the two 10 Gb interfaces,
numbered eth2 and eth3 in the operating system.
For the embedded switch architecture, VLAN30 is used for carrying both IPv4 and IPv6
traffic. There is no need for additional configuration from the IPv4 section. The switch
configuration is the same as for Top-of-Rack, and is shown in Example 5-46.
