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
