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
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
