Parameters
•
ipv6-address—Specifies the IPv6 address assigned to the interface. This
argument must be in the form documented in RFC4293 where the address
is specified in hexadecimal using 16-bit values between colons.
•
prefix-length—The length of the IPv6 prefix. A decimal value that indicates
how many of the high-order contiguous bits of the address comprise the
prefix (the network portion of the address). A slash mark must precede the
decimal value.
Default Configuration
No IP address is defined for the interface.
Command Mode
Interface Configuration
User Guidelines
The ipv6 address command cannot be applied to define an IPv6 address on an
ISATAP interface.
Using the no IPv6 address command without arguments removes all
manually-configured IPv6 addresses from an interface, including link local
manually configured addresses.
Example
The following example defines the IPv6 global address 2001:DB8:2222:7272::72
on vlan 100:
interface vlan 100
ipv6 address 2001:DB8:2222:7272::72/64
exit

Addresses are configured depending on the prefixes received in Router
Advertisement messages.
