Views
OSPF view
Default command level
2: System level
Parameters
acl-number: Specifies an ACL by its number in the range of 2000 to 3999 to filter redistributed routes.
ip-prefix-name: Specifies an IP prefix list by its name, a string of up to 19 characters, to filter redistributed
routes.
protocol: Specifies a protocol from which to filter redistributed routes. The protocol can be direct, static,
rip, ospf, isis, or bgp. If no protocol is specified, all redistributed routes are filtered.
process-id: Specifies a process by its ID in the range of 1 to 65535. This argument is available only when
the protocol is rip, ospf, or isis.
Usage guidelines
You can use this command to filter redistributed routes as needed.
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 the rule [ rule-id ] { deny | permit } ip
source sour-addr sour-wildcard command.
• To deny/permit a route with the specified destination and mask, use the rule [ rule-id ] { deny |
permit } ip source sour-addr sour-wildcard destination dest-addr dest-wildcard command.
The source keyword specifies the destination address of a route and the destination keyword specifies the
subnet mask of the route. (The subnet mask must be valid; otherwise, the configuration is ineffective.)

[Sysname] ospf 100
[Sysname-ospf-100] filter-policy 2000 export
# Configure ACL 3000 to permit only route 113.0.0.0/16 to pass, and reference ACL 3000 to filter
redistributed routes.
