Configuring basic IPv6 connectivity on a Layer 3 switch 5

•Configuring a global or site-local address with a manually configured or automatically computed interface ID for an interface.

•Automatically or manually configuring a link-local address for an interface.

•Configuring IPv6 anycast addresses

Configuring a global or site-local IPv6 address on an interface

Configuring a global or site-local IPv6 address on an interface does the following:

•Automatically configures an interface ID (a link-local address), if specified.

•Enables IPv6 on that interface.

Additionally, the configured interface automatically joins the following required multicast groups for that link:

•Solicited-node multicast group 2001:DB8:0:0:0:1:FF00::/104 for each unicast address assigned to the interface.

•Solicited-node for subnet anycast address for each unicast assigned address

•Solicited-node for anycast address 2001:DB8:0:0:0:1:FF00::0000

•All-nodes link-local multicast group 2001:DB8::1

•All-routers link-local multicast group 2001:DB8::2

The neighbor discovery feature sends messages to these multicast groups. For more information, refer to “IPv6 neighbor discovery configuration” on page 129.

Configuring a global or site-local IPv6 address with a manually configured interface ID

To configure a global or site-local IPv6 address, including a manually configured interface ID, for an interface, enter commands such as the following.

Brocade(config)#interface ethernet 1/2/1 Brocade(config-if-e1000-3/1)#ipv6 address 2001:DB8:12D:1300:240:D0FF: FE48:4672:/64

These commands configure the global prefix 2001:DB8:12d:1300::/64 and the interface ID ::240:D0FF:FE48:4672, and enable IPv6 on Ethernet interface 1/2/1.

Syntax: ipv6 address <ipv6-prefix>/<prefix-length>

You must specify the <ipv6-prefix>parameter in hexadecimal using 16-bit values between colons as documented in RFC 2373.

You must specify the <prefix-length>parameter as a decimal value. A slash mark (/) must follow the <ipv6-prefix>parameter and precede the <prefix-length>parameter.

To configure a /122 address on a VE enter commands similar to the following.

Brocade(config-vlan-11)#interface ve11

Brocade(config-vif-11)#ipv6	add 2001:DB8::1/122
Brocade(config-vif-11)#show	ipv6	interface
