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 .
Examples
# Permit IPv6 addresses with a mask length between 32 bits and 64 bits.
<Sysname> system-view
[Sysname] ip ipv6-prefix abc permit :: 0 greater-equal 32 less-equal 64
# Deny IPv6 addresses with the prefix being 3FFE:D00::/32, and prefix length being greater than or
equal to 32 bits.
<Sysname> system-view
[Sysname] ip ipv6-prefix abc deny 3FFE:D00:: 32 less-equal 128
reset ip ipv6-prefix
Syntax
reset ip ipv6-prefix [ ipv6-prefix-name ]
View
User view
Default level
2: System level
Parameters
ipv6-prefix-name: IPv6 prefix list name, a string of 1 to 19 characters.
Description
Use reset ip ipv6-prefix to clear the statistics of the specified IPv6 prefix list. If no name is specified, the
statistics of all IPv6 prefix lists will be cleared.
Examples
# Clear the statistics of IPv6 prefix list abc.
<Sysname> reset ip ipv6-prefix abc
