IP Router Configuration Command Reference
212 Router Configuration Guide
Description This command configures IPv6 for a router interface.
The no form of the command disables IPv6 on the interface.
Default not enabled
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.
Default none
Parameters ipv6-address/prefix-length — Specify the IPv6 address on the interface.
Values
eui-64 — When the eui-64 keyword is specified, a complete IPv6 address from the supplied
prefix and 64-bit interface identifier is formed. The 64-bit interface identifier is derived from
MAC address on Ethernet interfaces. For interfaces without a MAC address, for example
POS interfaces, the Base MAC address of the chassis should be used.
dad-disable
Syntax [no] dad-disable
Context config>router>interface>ipv6
Description This command disables duplicate address detection (DAD) on a per-interface basis. This prevents the
router from performing a DAD check on the interface. All IPv6 addresses of an interface with DAD
disabled, immediately enter a preferred state, without checking for uniqueness on the interface. This is
useful for interfaces which enter a looped state during troubleshooting and operationally disable
themselves when the loop is detected, requiring manual intervention to clear the DAD violation.
The no form of the command turns off dad-disable on the interface.
Default not enabled
ipv6-address/prefix: 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 1 to 128
