Parameters
ipv6-prefix-name: IPv6 prefix list name, a string of 1 to 19 characters, for uniquely specifying an IPv6
prefix list.
index-number: Index number, in the range of 1 to 65535, for uniquely specifying an IPv6 prefix list item.
An item with a smaller index-number will be matched first.
deny: Specifies the match mode for the IPv6 prefix list as deny. If a route matches the IPv6 prefix list, the
route neither passes the filter nor matches against the next item; if not, the route matches against the next
item (suppose the IPv6 prefix list has multiple items configured).
permit: Specifies the match mode for the IPv6 prefix list as permit. If a route matches the IPv6 prefix list,
it passes the IPv6 prefix list. If not, it matches against the next item (suppose the IPv6 prefix list has
multiple items configured).
ipv6-address prefix-length: Specifies an IPv6 prefix and prefix length. A prefix-length is in the range of 0
to 128. When specified as :: 0, the arguments match 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 ].
Description
Use ip ipv6-prefix to configure an IPv6 prefix list or an item of it.
Use undo ip ipv6-prefix to remove an IPv6 prefix list or an item.
No IPv6 prefix list is configured by default.
An IPv6 prefix list may have multiple items, and each of them specifies a range of IPv6 prefixes. The
relation between items is logic OR. If a route passes an item of it, the route will pass the IPv6 prefix list.
The IPv6 prefix range is determined by prefix-length and [ min-prefix-length, max-prefix-length ]. If both
mask-length and [ min-mask-length, max-mask-length ] are specified, then the IPv6 addresses must satisfy
both of them.
If ipv6-address prefix-length is specified as :: 0, only the default route matches.
To match all routes, configure :: 0 less-equal 128.
