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”
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
