ipv6 prefix prefix-number ipv6-prefix/prefix-length
undo ipv6 prefix prefix-number

Parameters
prefix-number: Specifies a prefix ID in the range of 1 to 1024.
ipv6-prefix/prefix-length: Specifies a prefix and its length. The value range for the prefix-length argument is 1 to 128.
Usage guidelines
You can not use the ipv6 prefix command to modify an existing static prefix.
Dynamic IPv6 prefixes obtained from DHCPv6 servers cannot be manually removed or modified.
A static IPv6 prefix can have the same prefix ID with a dynamic IPv6 prefix, but the static one takes precedence over the dynamic one.
Examples
# Create static IPv6 prefix 2001:0410::/32 with prefix ID 1
<Sysname> system-view [Sysname] ipv6 prefix 1 2001:0410::/32
