ipv6 prefix-list (IPv6 Prefix List)
Use this command to create an IPv6 prefix list or an entry in an existing prefix list.
Use the no variant of this command to delete a whole prefix list or a prefix list entry.
Syntax ipv6 prefix-list <list-name> [seq <1-429496725>]
{deny|permit}
{any|<ipv6-prefix>}
[ge <0-128>] [le <0-128>]
ipv6 prefix-list <list-name> description <text>
no ipv6 prefix-list <list-name> [seq <1-429496725>]
no ipv6 prefix-list <list-name> [description <text>]
Mode
Global Configuration
Usage When the device processes a prefix list, it starts to match prefixes from the top of the prefix
list, and stops whenever a permit or deny occurs. To promote efficiency, use the seq parameter
and place common permits or denials towards the top of the list. If you do not use the seq
parameter, the sequence values are generated in a sequence of 5.
The parameters ge and le specify the range of the prefix lengths to be matched. The
parameters ge and le are only used if an ip-prefix is stated. When setting these parameters, set
the le value to be less than 128, and the ge value to be less than or equal to the le value and
greater than the ip-prefix mask length.
Prefix lists implicitly exclude prefixes that are not explicitly permitted in the prefix list. This
means if a prefix that is being checked against the prefix list reaches the end of the prefix list
without matching a permit or deny, this prefix will be denied.
Parameter Description
<list-name> Specifies the name of a prefix list.
seq <1-429496725> Sequence number of the prefix list entry.
deny Specifies that the prefixes are excluded from the list.
permit Specifies that the prefixes are included in the list.
<ipv6-prefix> Specifies the IPv6 prefix and prefix length in hexadecimal in
the format X:X::X:X/M.
any Any prefix match. Same as ::0/0 le 128.
ge <0-128> Specifies the minimum prefix length to be matched.
le <0-128> Specifies the maximum prefix length to be matched.
description Prefix list specific description.
<text> Up to 80 characters of text description of the prefix list.
