Parameters
acl6-number: Number of a basic or advanced IPv6 ACL used to filter redistributed routes before
advertisement, ranging from 2000 to 3999. For ACL information, see Access Control Configuration
Guide.
ipv6-prefix-name: Name of an IPv6 prefix list used to filter the redistributed routes before advertisement,
a case-sensitive string of 1 to 19 characters. For IPv6 prefix list information, see Network Mangement
Configuration Guide.
route-policy-name: Name of a routing policy used to filter the redistributed routes before advertisement,
a case-sensitive string of 1 to 63 characters. For routing policy information, see Network Mangement
Configuration Guide.
protocol: Routing protocol from which the redistributed routes are to be filtered. The routing protocol can
be bgp4+, direct, isisv6, ospfv3, ripng or static. If no protocol is specified, routes redistributed from all
protocols are filtered.
process-id: Process ID of the routing protocol, ranging from 1 to 65535. This argument is available when
the protocol is isisv6, ospfv3 or ripng.
Description
Use ipv6 filter-policy export to configure IPv6 IS-IS to filter redistributed routes before advertisement.
Use undo ipv6 filter-policy export to disable the filtering.
The filtering is disabled by default.
In some cases, only routes satisfying certain conditions will be advertised. You can configure the filtering
conditions using the ipv6 filter-policy command.
You can use the ipv6 filter-policy export command, which filters redistributed routes only when they are
advertised to other routers, in combination with the ipv6 import-route command.
• If no protocol is specified, routes redistributed from all protocols are filtered before advertisement.
• If a protocol is specified, only routes redistributed from the protocol are filtered before
advertisement.
If you want to reference an advanced ACL (with a number from 3000 to 3999) in the command or in the
routing policy, 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).
Related commands: ipv6 filter-policy import.
