Configuring basic IPv6 connectivity on a Layer 3 switch
• 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 FF02:0:0:0:0:1: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 FF02:0:0:0:0:1:FF00::0000
• All-nodes link-local multicast group FF02::1
• All-routers link-local multicast group FF02::2
The neighbor discovery feature sends messages to these multicast groups. For more information,
refer to “IPv6 neighbor discovery configuration” on page 384.
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 3/1
Brocade(config-if-e1000-3/1)#ipv6 address 2001:200:12D:1300:240:D0FF:
FE48:4672:/64
These commands configure the global prefix 2001:200:12d:1300::/64 and the interface ID
::240:D0FF:FE48:4672, and enable IPv6 on Ethernet interface 3/1.
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)#int ve11
Brocade(config-vif-11)#ipv6 add 2020::1/122
Brocade(config-vif-11)#sh ipv6 int
Routing Protocols : R - RIP O - OSPF
Interface Status Routing Global Unicast Address
VE 11 up/up 2020::1/122
Brocade(config-vif-11)#sh ipv6 route
