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.
Views

Predefined user roles

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, or 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.
Using the filter-policy export command filters only routes redistributed by the import-route command. If the import-route command is not configured to redistribute routes from other protocols and other OSPFv3 processes, use of the filter-policy export command does not take effect.
Examples
# Use IPv6 prefix list abc to filter redistributed routes.
<Sysname> system-view [Sysname] ipv6 prefix-list abc permit 2002:1:: 64 [Sysname] ospfv3 [Sysname-ospfv3-1] filter-policy prefix-list abc export
# Configure IPv6 ACL 3000 to permit only route 2001::1/128. Use ACL 3000 to filter redistributed routes.
<Sysname> system-view [Sysname] acl ipv6 number 3000 [Sysname-acl6-adv-3000] rule 10 permit ipv6 source 2001::1 128 destination ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff 128 [Sysname-acl6-adv-3000] rule 100 deny ipv6 [Sysname-acl6-adv-3000] quit [Sysname] ospfv3 [Sysname-ospfv3-1] filter-policy 3000 export
