65535. An item with a smaller index number is matched first. If you do not specify this option, the
index number starts from 10 and increments by 10 for each of the consecutive IPv6 prefix list items.
: Specifies the deny mode. If a route matches the item, the route is denied without being

compared with the next item. If a route does not match the item, the route is compared with the next
item.
permit : Specifies the permit mode. If a route matches the item, it passes the IPv6 prefix list. If a
route does not match the item, the route is compared with the next item.

Usage guidelines
An IPv6 prefix list is used to filter IPv6 addresses. An IPv6 prefix list can have multiple items, and
each of them specifies a range of IPv6 prefixes. The relation between the items is logical OR. A route
passing an item passes the IPv6 prefix list. A route passing no item does not pass the IPv6 prefix list.
If the
ipv6-address prefix-length
matches.
To match all routes, configure :: 0
Examples
# Permit IPv6 addresses with a mask length between 32 bits and 64 bits.
<Sysname> system-view
[Sysname] ipv6 prefix-list abc permit :: 0 greater-equal 32 less-equal 64
# Deny IPv6 addresses with a prefix 3FFE:D00::/32 and a prefix length greater than or equal to 32
bits.
<Sysname> system-view
[Sysname] ipv6 prefix-list abc deny 3FFE:D00:: 32 less-equal 128
