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 1 to 65535, for uniquely specifying an IPv6 prefix list item.
An item with a smaller
index-number
will be matched first.
permit
: Specifies the matching mode for the IPv6 prefix list item as permit, that is, if a route matches
the item, it passes the IPv6 prefix list without needing to match against the next item; if not, it will match
against the next item (suppose the IPv6 prefix list has multiple items configured).
deny
: Specifies the matching mode for the IPv6 prefix list item as deny, that is, if a route matches the
item, the route neither passes the filter nor matches against the next item; if not, the route will match
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 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 the
ip
ipv6-prefix
command to configure an IPv6 prefix list or an item of it.
Use the
undo
ip
ipv6-prefix
command 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, namely, 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.
