Parameters
prefix-list-name: Specifies a name for the IPv6 prefix list, a case-sensitive string of 1 to 63 characters.
index-number: Specifies an index number for an IPv6 prefix list item, in the range of 1 to 65535. An item
with a smaller number is matched first.
deny: Specifies the deny mode. If a route matches the item, the route is denied without matching against
the next item. If not, the route matches against the next item (suppose the IPv6 prefix list has multiple
items).
permit: Specifies the permit mode. If a route matches the item, it passes the IPv6 prefix list. If not, it
matches against the next item (suppose the IPv6 prefix list has multiple items).
ipv6-address prefix-length: Specifies an IPv6 prefix and prefix length. The value range for the
prefix-length argument is 0 to 128. When specified as :: 0, the argument matches the default route.
greater-equal min-prefix-length: Greater than or equal to the minimum prefix length.
less-equal max-prefix-length: Less than or equal to the maximum prefix length.
The length relation is mask-length <= min-mask-length <= max-mask-length <= 128.
• If only the min-prefix-length is specified, the prefix length range is [ min-prefix-length, 128 ].
• If only the max-prefix-length is specified, the prefix length range is [ prefix-length,
max-prefix-length ].
• If both the min-prefix-length and max-prefix-length are specified, the prefix length range is
[ min-prefix-length, max-prefix-length ].
Usage guidelines
An IPv6 prefix list can have multiple items, and each of them specifies a range of IPv6 prefixes. The
relation between items is logical OR. If a route passes an item, it passes the IPv6 prefix list.
If ipv6-address prefix-length is specified as :: 0, only the default route matches.
To match all routes, configure :: 0 less-equal 128 .
Examples
# Permit IPv6 addresses with a mask length between 32 bits and 64 bits.
<Sysname> system-view
[Sysname] ipv6 prefix-list abc permit :: 0 greater-equal 32 less-equal 64
# Deny IPv6 addresses with a prefix 3FFE:D00::/32 and a prefix length greater than or equal to 32 bits.
<Sysname> system-view
[Sysname] ipv6 prefix-list abc deny 3FFE:D00:: 32 less-equal 128
