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

Usage guidelines
The default gateway sends an ICMPv6 redirect message to the source of an IPv6 packet to inform
the source of a better first hop.
Sending ICMPv6 redirect messages enables hosts that hold few routes to establish routing tables
and find the best route. Because this function adds host route into the routing tables, host
performance degrades when there are too many host routes. As a result, sending ICMPv6 redirect
messages is disabled by default.
