outbound Inter-Area-Prefix-LSAs in OSPFv3 Area 1.
<Sysname> system-view
[Sysname] ospfv3 1
[Sysname-ospfv3-1] area 1
[Sysname-ospfv3-1-area-0.0.0.1] filter prefix-list my-prefix-list import
[Sysname-ospfv3-1-area-0.0.0.1] filter 2000 export
filter-policy export (OSPFv3 view)
Use filter-policy export to configure OSPFv3 to filter redistributed routes.
Use undo filter-policy export to remove the configuration.
Syntax
filter-policy { acl6-number | prefix-list prefix-list-name } export [ protocol [ process-id ] ]
undo filter-policy export [ protocol [ process-id ] ]
Default
Redistributed routes are not filtered.

Parameters
acl6-number: Specifies an IPv6 ACL by its number in the range of 2000 to 3999 to filter redistributed
routes by destination address.
prefix-list-name: Specifies an IPv6 prefix list by its name, a case-sensitive string of 1 to 63 characters, to
filter redistributed routes by destination address.
protocol: Filters routes redistributed from the specified routing protocol, which can be bgp4+, direct,
isisv6, ospfv3, ripng, and static. If no protocol is specified, this command filters all redistributed routes.
process-id: Specifies a process by its ID in the range of 1 to 65535. This argument is available only when
the protocol is ripng, ospfv3, or isisv6.
Usage guidelines
To reference an advanced ACL (with a number from 3000 to 3999) in the command, configure the ACL
in one of the following ways:
• To deny/permit a route with the specified destination, use rule [ rule-id ] { deny | permit } ipv6
source sour sour-prefix.
• To deny/permit a route with the specified destination and prefix, use rule [ rule-id ] { deny | permit }
ipv6 source sour sour-prefix destination dest dest-prefix.
The source keyword specifies the destination address of a route, and the destination keyword specifies
the prefix of the route. The prefix must be contiguous. Otherwise, the configuration does not take effect.
