ipv6 address
Use ipv6 address to configure an IPv6 global unicast address for an interface.
Use undo ipv6 address to remove the IPv6 global unicast address of the interface.
Syntax
ipv6 address { ipv6-address prefix-length | ipv6-address/prefix-length }
undo ipv6 address [ ipv6-address prefix-length | ipv6-address/prefix-length ]
Default
No IPv6 global unicast address is configured for an interface.

Parameters
ipv6-address: Specifies an IPv6 address.
prefix-length: Specifies a prefix length in the range of 1 to 128.
Usage guidelines
Like public IPv4 addresses, IPv6 global unicast addresses are assigned to ISPs. This type of address allows for prefix aggregation to reduce the number of global routing entries.
If you do not specify any parameters, the undo ipv6 address command removes all IPv6 addresses of an interface.
Examples
# Set the IPv6 global unicast address of VLAN-interface 100 to 2001::1 with prefix length 64.
Method 1:
<Sysname> system-view [Sysname] interface vlan-interface 100 [Sysname-Vlan-interface100] ipv6 address 2001::1/64
Method 2:
<Sysname> system-view [Sysname] interface vlan-interface 100 [Sysname-Vlan-interface100] ipv6 address 2001::1 64
