address
Syntax address ipv6-address/prefix-length [eui-64]
no address ipv6-address/prefix-length
Context config>router>if>ipv6
Description This command assigns an IPv6 address to the interface.
The following adapter cards support the full IPv6 subnet range for interface IP addresses:
• 6-port Ethernet 10Gbps Adapter card
• 8-port Gigabit Ethernet Adapter card, version 2 and version 3
• 2-port 10GigE (Ethernet) Adapter card (on the v-port)
• 10-port 1GigE/1-port 10GigE X-Adapter card
For these cards, the supported interface IP address prefixes are from /4 to /127, and /128 on system or
loopback interfaces.
For all other cards, modules, and ports (including the v-port on the 2-port 10GigE (Ethernet) module),
the supported interface IP address prefixes are from /4 to /64, and /128 on system or loopback
interfaces.
Default n/a
Parameters ipv6-address/prefix-length — the IPv6 address on the interface
Values ipv6-address x:x:x:x:x:x:x:x (eight 16-bit pieces)
x:x:x:x:x:x:d.d.d.d
x: [0 to FFFF]H
d: [0 to 255]D
prefix-length {4 to 128} | {4 to 64 | 128}
eui-64 — when the eui-64 keyword is specified, a complete IPv6 address from the supplied prefix
and 64-bit interface identifier is formed. If a port has not been assigned to the interface, the
64-bit interface identifier is derived from the system MAC address and does not change after
a port is added. The same behavior applies for the link-local address.
neighbor
Syntax neighbor ipv6-address mac-address
no neighbor ipv6-address
Context config>router>if>ipv6
Description This command configures an IPv6-to-MAC address mapping on the interface. Use this command if a
directly attached IPv6 node does not support ICMPv6 neighbor discovery or a static address must be
used. This command can only be used on Ethernet interfaces. The ipv6-address must be on the subnet
that was configured from the IPv6 address command or a link-local address.
