ipv6-prefix/prefix-length: Specifies a prefix and the prefix length. The value range for the prefix-length
argument is from 1 to 128.
Usage guidelines
You cannot execute the ipv6 prefix command to modify an existing static prefix.
When a DHCPv6 client obtains an IPv6 prefix from a DHCP server, the IPv6 prefix is dynamically
generated. You cannot modify or remove the dynamically generated prefix.
The prefix IDs of a static IPv6 prefix and a dynamical IPv6 prefix cannot be the same.
Examples
# Create static IPv6 prefix 2001:0410::/32 with prefix ID 1.
<Sysname> system-view
[Sysname] ipv6 prefix 1 2001:0410::/32
