FILTER
ip ospf database-filter
Overview
This command turns on the LSA database-filter for a particular VLAN interface.
The
no
variant of this command turns off the LSA database-filter.
Syntax
ip ospf [<
ip-address
>] database-filter all out
no ip ospf [<
ip-address
>] database-filter
Default
By default, all outgoing LSAs are flooded to the interface.
Mode
Interface Configuration for a VLAN interface.
Usage
OSPF floods new LSAs over all interfaces in an area, except the interface on which
the LSA arrives. This redundancy ensures robust flooding. However, too much
redundancy can waste bandwidth and might lead to excessive link and CPU usage
in certain topologies, resulting in destabilizing the network. To avoid this, use the
ip ospf database-filter
command to block flooding of LSAs over specified
interfaces.
Example
awplus#

awplus(config)#

ip ospf database-filter all out
Parameter
Description
<
ip-address
>
The IPv4 address of the interface, in dotted decimal notation.
