IPv6

Table 1 lists the individual Brocade FastIron switches and the IPv6 features they support. These

features are supported with premium IPv6 devices running the full Layer 3 software image.

Static IPv6 route configuration

NOTE

Static IPv6 route configuration is supported only with the IPv6 Layer 3 license on FSX devices and

the full Layer 3 image on other devices.

You can configure a static IPv6 route to be redistributed into a routing protocol, but you cannot

redistribute routes learned by a routing protocol into the static IPv6 routing table.

NOTE

The maximum IPv6 static routes supported on an ICX 6450 device is 1070.

Before configuring a static IPv6 route, you must enable the forwarding of IPv6 traffic on the Layer 3

switch using the ipv6 unicast-routing command and enable IPv6 on at least one interface by

configuring an IPv6 address or explicitly enabling IPv6 on that interface. For more information on

performing these configuration tasks, refer to “Configuring IPv4 and IPv6 protocol stacks” section

in the FastIron Ethernet Switch Administration Guide.

Configuring a static IPv6 route

To configure a static IPv6 route for a destination network with the prefix 2001:DB8::0/32, a

next-hop gateway with the global address 2001:DB8:0:ee44::1, and an administrative distance of

110, enter the following command.

Brocade(config)#ipv6 route 2001:DB8::0/32 2001:DB8:2343:0:ee44::1 distance 110
