filter-policy export (OSPFv3 view) Syntax filter-policy { acl6-number | ipv6-prefix ipv6-prefix-name } export [ bgp4+ | direct | ospfv3 process-id | ripng process-id | static ] View undo filter-policy export [ bgp4+ | direct | ospfv3 process-id | ripng process-id | static ] OSPFv3 view Default level 2: System level Parameters acl6-number: Specifies the ACL6 number, ranging from 2000 to 3999. ipv6-prefix ipv6-prefix-name: Specifies the name of an IPv6 prefix list, a string of up to 19 characters. bgp4+: Filters IPv6 BGP routes. direct: Filters direct routes. ospfv3 process-id: Specifies to filter the routes of an OSPFv3 process, which is in the range of 1 to 65535. ripng process-id: Specifies to filter the routes of a RIPng process, which is in the range of 1 to 65535. static: Specifies to filter static routes. Description Use filter-policy export to filter redistributed routes. Use undo filter-policy export to remove the configuration. By default, IPv6 OSPFv3 does not filter redistributed routes. If no protocol is specified, all redistributed routes will be filtered. If you want to reference an advanced ACL (with a number from 3000 to 3999) in the command, the ACL should be configured with the rule [ rule-id ] { deny | permit } ipv6 source sour sour-prefix command to deny/permit a route with the specified destination, or with the rule [ rule-id ] { deny | permit } ipv6 source sour sour-prefix destination dest dest-prefix command to deny/permit a route with the specified destination and 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 valid; otherwise, the configuration is ineffective). 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, use of the filter-policy export command does not take effect. Examples # Filter all redistributed routes using IPv6 ACL 2001. system-view [Sysname] acl ipv6 number 2001 [Sysname-acl6-basic-2001] rule permit source 2002:1:: 64 [Sysname-acl6-basic-2001] quit [Sysname] ospfv3 252

Default level
2: System level
Parameters
acl6-number
: Specifies the ACL6 number, ranging from 2000 to 3999.
ipv6-prefix
ipv6-prefix-name
: Specifies the name of an IPv6 prefix list, a string of up to 19 characters.
bgp4+
: Filters IPv6 BGP routes.
direct
: Filters direct routes.
ospfv3
process-id
: Specifies to filter the routes of an OSPFv3 process, which is in the range of 1 to
65535.
ripng
process-id
: Specifies to filter the routes of a RIPng process, which is in the range of 1 to 65535.
static
: Specifies to filter static routes.
Description
Use
filter-policy export
to filter redistributed routes.
Use
undo filter-policy export
to remove the configuration.
By default, IPv6 OSPFv3 does not filter redistributed routes.
If no protocol is specified, all redistributed routes will be filtered.
If you want to reference an advanced ACL (with a number from 3000 to 3999) in the command, the ACL
should be configured with the
rule
[
rule-id
] {
deny
|
permit
}
ipv6 source
sour sour-prefix
command to
deny/permit a route with the specified destination, or with the
rule
[
rule-id
] {
deny
|
permit
}
ipv6 source
sour sour-prefix
destination
dest dest-prefix
command to deny/permit a route with the specified
destination and 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 valid; otherwise, the configuration
is ineffective).
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, use of the
filter-policy export
command does not take effect.
Examples
# Filter all redistributed routes using IPv6 ACL 2001.
<Sysname> system-view
[Sysname] acl ipv6 number 2001
[Sysname-acl6-basic-2001] rule permit source 2002:1:: 64
[Sysname-acl6-basic-2001] quit
[Sysname] ospfv3
